IP foresight
by Finger in the Infodike 19 Mar '95

19 Mar '95

Just to put a little perspective on this whole debate about forseeing your IP address needs, I was cleaning out my desk and found a copy of a message sent on June 5, 1984 to me (then haas(a)utah-20.arpa) thanking me for getting the X.25 connection to Japan working. The whole Internet has evolved in the 11 years since. I'm a fairly serious amateur student of technology history, and I'm not aware of any other technology that has grown at comparable speed. I think it would be nice if we gave the folks at the InterNIC a break, and recognize that they are attempting to deal with a situation which is basically impossible. The only thing which I can see offering any real hope is IPng, with RFC 1597 as a plausible stopgap - at least I hope it's plausible since I'm recommending it to clients, most of whom are paranoid about security and want a firewall anyway. -- Walt -------

Re: Internic address allocation policy
by Phil Dykstra 18 Mar '95

18 Mar '95

Speaking as a national network with millions of dollars invested (AAI), I tried for three months to get a Class B assigned. The total number of hosts didn't justify it, even though it was nationwide with many geographic sites that we wanted to subnet, and even though we are doing research in ATM SVC signalling, ATM multicast, NHRP, etc. So we got a CIDR block of Class C's, and as expected, many of our systems are turning out not to handle the required subnet masks without hacks. While this has all been a pain I wished to avoid, we do really need to get this CIDR stuff to work everywhere, and we really are running out of address space. So while I agree that address space struggles with the InterNIC aren't pleasant (or quick), I think they are doing what needs to be done to conserve a scarce, dwindling resource. - Phil

decreasing traffic

We are about six weeks away from the retirement of the NSFNET backbone service. In looking at the traffic statistics for the various access points to the NSFNET service, most ENSSes have seen a reduction in traffic into the backbone, but there is still a significant amount of traffic which still traverses the NSFNET. Merit has posted a histogram on nic.merit.edu:/nsfnet/statistics/ top10.transition.ps which shows the number of packets into the nodes of the backbone in the last 6 months (Sept'94 to Feb'95). The 10 nodes which are shown on this graph are the top 10 originators of traffic into the backbone in February 1995. If you are attached to one of the nodes highlighted on our graph, please be aware that these attachments to the NSFNET Backbone Service will be retired as of April 30, 1995. More detailed information about the packets and bytes on the NSFNET Backbone Service can be found on nic.merit.edu:/nsfnet/statistics/*. --Elise

========================================================== The "Expanded Listings" section of this NWG report has been retired since it is sorted by countries and network organization addresses. The replacement configuration generation system is based on the Internet Routing Registry (briefly called the "Global Routing Registry"). See the file ftp.ra.net:pub/radb/OVERVIEW for more information. The remainder of this report will also be retired shortly. ========================================================== The following Midlevel/Regional peering sessions have also been added: AS 1239 - SprintLink - ENSS 147 Peer: 192.41.177.241 - Sprint - (192.41.177.241) AS 3561 - MCI-RESTON - ENSS 147 Peer: 192.41.177.181 - MCI - cpe2.washington.mci.net Peer: 198.32.130.227 - MCI - cpe3.chicago.mci.net AS690 CIDR Squeezings Report: 11180 Nets, 183 ASs, 3118 Aggregates ------------------------------------------------------------------- 11180 (83%) of the ever-announced more-specific routes within aggregates have been withdrawn. 1305 of those were withdrawn within the last week. 170 the week before that. 410 the week before that. 183 ASs have registered aggregates in the PRDB. 164 of those are announcing aggregates. 87 have withdrawn at least one more specific route. 3118 Aggregates are configured. 2102 of these were Top-Level Aggregates (not nested in another aggregate). 1612 of these are being announced to AS690. 1019 of those have at least one subnet configured (the other 593 may be saving the Internet future subnet announcements). 874 have stopped announcing at least one configured more specific route. 840 have stopped announcing half of their configured more specific routes. 801 have stopped announcing most (80%) of their more specific routes. See home.merit.edu:pub/nsfnet/cidr/cidr_savings for more detail. ----------------------------------------------------------- ========================================================== The configuration reports which reflect today's update will be available for anonymous ftp on nic.merit.edu by 08:00 EST : configuration reports -- nic.merit.edu:nsfnet/announced.networks: as-as.now as-gw.now ans_core.now country.now net-comp.now nets.doc nets.non-classful nets.tag.now nets.unl.now NSS routing software configuration files -- nic.merit.edu:nsfnet/backbone.configuration: gated.nss<NSS number>.t3p Information is also avaiable through the PRDB whois server. Type "whois -h prdb.merit.edu help" for details. -------------------------------------------------------------------------- PRDB CHANGES: (Updated January 19, 1994) As of 1/19/95, ACKs and NAKs will no loger be required (or even read) in the processing of NACRs. In early 1995, as part of the transition to the new Internet Routing Registry (IRR), the Policy Routing Database (PRDB) will be retired. Many of the functions of the PRDB (including generation of router configurations for NSFNET) will be produced based on data from the Global Routing Registry. This change to the NSFNET Backbone service will involve the following changes: - The method for submitting new nets to be routed over AS690 will change. Instead of submitting a NACR to nsfnet-admin(a)merit.edu, you will need to submit a "route template" to auto-dbm(a)ra.net . - Additions and entries to the new registry will be made by the Home AS which creates the route for each net, rather than being submitted by a AS690 peer AS. - Most of the PRDB reports (listed above) will no longer be produced. Equivalent information for most of these reports is available from the global Routing Registry. These are major changes to the system. These changes are being made in order to migrate NSFNET customers and the global user community to a global Internet Routing Registry system, which will be more capable of supporting user needs after the termination of the NSFNET Backbone services in April 1995. For more information, set your web browser to http://www.ra.net/rrinfo.html , or use anonymous ftp to obtain the files "OVERVIEW" and from the directory "ftp.ra.net:pub/radb". Merit would like to minimize the number of problems that this transition may cause you. In order to help us help you through the transition, please send your concerns, your needs, and suggestions on how we can make this happen smoothly to merit-ie(a)merit.edu. The archived discussion list "db-disc(a)merit.edu" also exists for discussion of PRDB and RADB issues. Send a message to "db-disc-request(a)merit.edu" to subscribe. --Dale Johnson (dsj(a)merit.edu) -------------------------------------------------------------------------- Please send all requests for configuration changes to nsfnet-admin(a)merit.edu using the NSFNET configuration forms. The forms are available on-line from the nic.merit.edu machine. Use ftp and the anonymous login to get on the machine. Do a "cd nsfnet/announced.networks" and get the files template.net, template.net.README, template.gate, and template.as. *** Note: As of March 1, 1994, NSFNET AUP NACRs must use the template.net *** (NACR) version 7.1, or the NACR will be returned unprocessed. ******************************* --Stephen McNutt Merit/NSFNET smm(a)merit.edu --Steven J.

15 Mar '95

February 1995 INTERNET MONTHLY REPORTS ------------------------ The purpose of these reports is to communicate to the Internet Research Group the accomplishments, milestones reached, or problems discovered by the participating organizations. This report is for Internet information purposes only, and is not to be quoted in other publications without permission from the submitter. Each organization is expected to submit a 1/2 page report on the first business day of the month describing the previous month's activities. These reports should be submitted via network mail to: Ann Cooper (IMR(a)ISI.EDU) Requests to be added or deleted from the Internet Monthly report list should be sent to "imr-request(a)isi.edu". Details on obtaining the current IMR, or back issues, via FTP or EMAIL may be obtained by sending an EMAIL message to "rfc-info(a)ISI.EDU" with the message body "help: ways_to_get_imrs". For example: To: rfc-info(a)ISI.EDU Subject: getting imrs help: ways_to_get_imrs Cooper [Page 1] Internet Monthly Report February 1995 TABLE OF CONTENTS INTERNET ARCHITECTURE BOARD INTERNET RESEARCH REPORTS . . . . . . . . . . . . . . . . page 3 RESOURCE DISCOVERY AND DIRECTORY SERVICE . . .. . . . page 3 INTERNET ENGINEERING REPORTS . . . . . . . . . . . . . . page 4 Internet Projects ANSNET/NSFNET BACKBONE ENGINEERING . . . . . . . . . . . page 9 DANTE . . . . . . . . . . . . . . . . . . . . . . . . . . page 9 INTERNIC. . . . . . . . . . . . . . . . . . . . . . . . . page 11 ISI . . . . . . . . . . . . . . . . . . . . . . . . . . . page 13 MERIT/NSFNET ENGINEERING. . . . . . . . . . . . . . . . . page 24 MIDNET. . . . . . . . . . . . . . . . . . . . . . . . . . page 27 UCL . . . . . . . . . . . . . . . . . . . . . . . . . . . page 28 CALENDAR OF EVENTS . . . . . . . . . . . . . . . . . . . . . page 29 Rare List of Meetings. . . . . . . . . . . . . . . . . . . page 33 Cooper [Page 2] Internet Monthly Report February 1995 INTERNET RESEARCH REPORTS ------------------------- RESOURCE DISCOVERY AND DIRECTORY SERVICE ---------------------------------------- The Internet Research Task Force research group on Resource Discovery has been developing and experimenting with the Harvest system for the past 1.5 years. Harvest provides an integrated set of tools to gather, extract, organize, search, cache, and replicate relevant information across the Internet. With modest effort users can tailor Harvest to digest information in many different formats, and offer custom search services on the Internet. Moreover, Harvest makes very efficient use of network traffic, remote servers, and disk space. In the past few months we have made significant improvements to the system, allowing well-controlled specifications of the information gathering workload, much better gathering and indexing performance, support for more data formats, more sophisticated caching and replication, ports to popular platforms, and much more easily installed and used binary distributions of the basic system. At present we are working on extending the system to support taxonomies and query routing, more complex data models, interfaces with other popular systems and products (such as Verity's and WAIS Inc.'s search engines, SGML, and SQL search engines), more customizable searching schemes, non-textual index/search engines, and a number of experiments concerning system scalability. We are actively pursuing collaborative efforts with other projects in all sectors - commercial, government, academic, and others.

Cooper [Page 3] Internet Monthly Report February 1995 INTERNET ENGINEERING REPORTS ---------------------------- 1. Let me remind everyone that the next IETF meeting will be in Danvers, Massachusetts (a suburb of Boston) from April 3-7, 1995. Logistic information has already been posted to the IETF Announcement list. The summer IETF meeting will be held in Stockholm, Sweden the week of July 17-21, 1995. Due to the meeting costs, the IETF attendance fee for the Stockholm meeting will be US$300. Hotel information has been sent to the Announcement list, and attendees are encouraged to make their plane and hotel reservations. The IETF Secretariat is NOT accepting registrations for the Stockholm meeting at this time. Following Stockholm, the IETF will be meeting in Dallas, Texas on December 4-8, 1995. Our local host for this meeting is MCI. Once all the arrangements have been made, notifications will be sent to the IETF Announcement list. Remember that information on future IETF meetings can be always be found in the file 0mtg- sites.txt which is located on the IETF shadow directories.

The total packet count into the network including all ENSS serial interfaces was 72,065,096,991 down 13.41% from January. The decrease is due to the on-going decommissioning of the NSFNET backbone service. ROUTER FORWARDING TABLE STATISTICS The maximum number of destinations announced to ANSnet during February was 22,292 up 5.22% from January. The number of network destinations configured for announcement to the ANSnet but never announced (silent nets) during February was 23,269 Jordan Becker (becker(a)ans.net) DANTE ----- __________________________________________________________________ * * A bi-monthly electronic news bulletin * * reporting on the activities of DANTE, * the company that provides international * network services for the European THE WORKS OF D A N T E research community. No.8, March 1995 Editor: Josefien Bersee __________________________________________________________________ NEW EBONE-EUROPANET GATEWAY Since 1 February the fourth consecutive interconnect arrangement between EuropaNET and Ebone has been in operation. As the capacity of the previous gateway was insufficient, the new gateway has a capacity of 1 Mbps, and will shortly be upgraded to 1.5 Mbps. The cost is shared between Ebone and some of DANTE's customers. The current arrangement will cover the first 9 months of 1995. Cooper [Page 9] Internet Monthly Report February 1995 At the same time DANTE regrets not to have been able so far to persuade EUnet to serialize their connection to EuropaNET. DANTE has been providing EUnet with a free 64 kbps access, but in practice much more capacity is used. Therefore DANTE asked EUnet to increase their connection rate accordingly and to serialize the connection in October last year. Unfortunately, DANTE can not indefinitely offer free and unlimited connectivity to some networks while charging others. HIGH SPEED PROGRESS While the EuroCAIRN study is now in the hands of the EuroCAIRN Committee DANTE has already taken the next step on the road to a high speed network for European research. DANTE submitted an outline proposal under a joint initiative as part of the EC Fourth Framework Programme of DG III F and DGXIII C to support the European interconnection of national research and university networks at 34- 155 Mbps. The initiative is an integral part of the existing Call for Proposals for the Information Technologies Programme (Esprit) and the Telematics Application Programme. DANTE will act as coordinating partner in a consortium together with a number of national research networks. A decision on which projects will be awarded funding will be made be made in the second half of 1995. Obviously DANTE is keen to get the opportunity to execute the implementation plan it has presented as part of the EuropCAIRN report. DANTE AT CEBIT DANTE is pleased to announce that, by courtesy of DFN, it will be present at CeBIT, the leading annual IT event in Hannover, Germany. DANTE was invited to share the DFN stand. DANTE will take the opportunity to increase visibility of its own activities and European research networking in general. In particular DANTE will spread the word on its 'high speed' activities so far. DFN and DANTE can be found in Hall 22, Stand D36. More information can be found on a special www page, URL: http://www.dante.net/CeBIT/CeBIT.html VIRTUAL PROJECT LIBRARY DANTE is taking part in an EC Information Engineering Feasibility Project initiated by the French company Matra Marconi Space. The project is called Virtual Project Library and it sets out to create a mechanism which will enable project participants distributed all over Europe working together on a project to access, use and store project information over the network. This may sound very familiar to the networking community but in the commercial world the Cooper [Page 10] Internet Monthly Report February 1995 Internet is not yet the standard information medium, security being one major concern. DANTE was invited to join as partner to assess and advise on the pan-European networking options and limitations for creating such a mechanism. The kick-off meeting for the seven- month project took place in February. NEW STAFF Vincent Berkhout (NL) started work for DANTE on 16 January 1995. He will be working as Applications Engineer. Initially he will concentrate on directory issues. Vincent graduated as 'Telematics Engineer' at the Hogeschool Utrecht in 1992. For his final thesis he worked at SURFnet doing research on the technical infrastructure of X.500. After that he joined the post-graduate Technology Designer program at the University of Twente where he worked as a member of the Network Management discipline group. ________________________________________________________________ DANTE - Lockton House - Clarendon Road - Cambridge - CB2 2BH - UK telephone +44 1223 302992 fax +44 1223 303005 -- please note the new area code for Cambridge is (0)1223 -- E-mail dante(a)dante.org.uk S=dante; O=dante; P=dante; A=mailnet; C=fi WWW server http://www.dante.net/ Gopher server gopher://gopher.dante.net/ Anonymous ftp ftp://ftp.dante.net/pub/ __________________________________________________________________ INTERNIC -------- INTERNIC DIRECTORY AND DATABASE SERVICES As of February 28, InterNIC Directory and Database Services took over support of some of the services previously supported by InterNIC Information Services. The InfoGuide will be available on ds.internic.net (pending resolution of some copyright issues), and some popular mailing lists will move as well. The scout-report and net-happenings mailing lists have been moved to DS machines. The mailing list transition is causing some load problems at the moment (scout-report, for example, has 20,000 recipients). We are ordering additional hardware to handle the Cooper [Page 11] Internet Monthly Report February 1995 load generated by the mailing lists and we expect their performance to be back to normal soon. The lists are held on a machine named dsmail.internic.net, but we have aliases in place so requests sent to majordomo(a)is.internic.net will be handled properly. To minimize impact from this changeover on InterNIC users, the name is.internic.net has been changed to point to the Directory and Database Services machines and we will maintain the same directory structure for the IS information that it had on the IS machine. Thus users will be able to continue to use URLs and Gopher links to files and directories on is.internic.net. This also means that subscription requests for the mailing lists can still be sent to majordomo(a)is.internic.net. There are no changes to the existing service offered on the ds machines. A reminder - if you would like to help the Internet community find a resource that you offer, send mail to admin(a)ds.internic.net and we will send information about listing your resource in the Directory of Directories. by Rick Huber <rvh(a)ds.internic.net> INTERNIC REGISTRATION SERVICES I. Significant Events InterNIC Registration Services assigned over 10,056 network addresses and registered over 4,190 domains. Three top level domains were registered this month for Anguilla (AI), Cote d'Ivoire (CI), and Guam (GU). Knowledgenet, Inc. has filed suit against Network Solutions and David L. Boone over the name knowledgenet.com. Network Solutions has engaged outside counsel to represent us in this suit. Due to a continuance, the next court filing has been pushed back to early March. This case could establish precedence that refutes InterNIC Registration Service's current policy of first-come first served by binding trademarked names with a domain name. During the month of February, increased volume of requests has increased the backlog from 10 days processing time to 15 days processing time. There are approximately 5,000 new domain requests in the queue to be processed. Adjustments in processes/staff are being made, as well as ordering additional equipment to continue to accommodate the tremendous growth currently being experienced by Registration Services. Cooper [Page 12] Internet Monthly Report February 1995 Mark Kosters attended the two (2) day NANOG meeting in Denver, Colorado the week of February 6, 1995. Mark gave a presentation on the status of InterNIC Registration Services (RS) demonstrating its' current load. He also, participated in IP allocation and assignment strategies. II. Current Status During the month of February 1995, InterNIC Registration Services received communications as shown below. The majority of the correspondence concerned the assignment and re-assignment of network numbers and the registration or change of domain names. E-mail 13,054 (hostmaster(a)internic.net) Postal/Fax 256 (primarily IP number requests) Phone 2,810 The Registrations Services host computer supported a large volume of information retrieval requests during the month of February.

Specifically, we have been working on the design and implementation of a transport protocol, DTP, that is optimized for fast intra-LAN round trip times, and the design of internet protocol mechanisms which would facilitate high performance wide-area transport protocols. Cooper [Page 13] Internet Monthly Report February 1995 A draft document describing the transport protocol, DTP, will be complete as results of the protcol implementation become available to support, or refute, the protocol design choices. A document describing mechanisms to support a zero-copy internet checksum is also in preparation. DTP: A HIGH-PERFROMANCE TRANSPORT PROTOCOL The properties of data transfer fidelity, order preservation and execute once-only semantics are provided through the physical design of a system bus and are taken for granted by software developers. Those properties are not provided by general-purpose networks. To successfully control a device across a network, those properties must be explicitly provided via protocols. A reliable transport protocol can ensure data fidelity, preserve ordering and provide at-most-once delivery of RPC messages. The rate at which RPC messages can be issued by a source host to a destination host is bound from above by the rate at which the source transport layer can send a message and receive its acknowledgement from the destination transport layer. Since commands to devices are often serially dependent, where the result of one command must be known before the next can be issued, effective substitution of a network for a system bus requires achieving very short RTTs in the transport layer. OVERVIEW OF A DEVICE TRANSPORT PROTOCOL A transport-layer protocol that is designed specificly for the control of devices over a network differs from a general-purpose transport-layer protocol such as TCP. The principal objectives are to satisfy required semantic communications properties for a Netstation device (NVD) operation while minimizing protocol-induced delays, both in the transport and application layers. Other transport-layer protocols have been defined that address somewhat similar application requirements. Perhaps chief among these are VMTP and the Reliable Data Protocol (RDP). The reasons for not using TCP for the control of NVDs echo the reasons that RDP was developed. Quoting from the RDP document RFC 908: "TCP is best suited to an environment where there is no obvious demarcation of data in a communications exchange. Much of the difficulty in developing a TCP implementation stems from the complexity of supporting this general byte-stream transfer, and thus a significant amount of complexity can be avoided by using another protocol. This is not just an implementation consideration, but also one of efficiency." Cooper [Page 14] Internet Monthly Report February 1995 The architecture of DTP builds on concepts found in VMTP, RDP and TCP, but is designed to take maximal advantage of the expected Netstation environment. In particular, emerging gigabit LANs provide an environment that is friendly to operation of a reliable transport protocol in several ways: (a) the delay*bandwidth product is generally shorter than a packet, (b) maximum packet lifetime is of little concern, (c) the cost of routing a packet is small and bandwidth is plentiful, and (d) packets are protected by a hardware checksum. A judgement was made that the majority of connections between devices and their owners are likely to be intra-LAN. If one accepts this premise, special attention should be paid in the transport layer to minimizing RTT for this class of traffic. DTP identifies messages sent across intra-LAN connections, which allows different flow-control and processing algorithms to be used for intra-LAN traffic. The design of DTP focuses on minimizing the end-to-end delay when a source application sends a message to a destination application. This is distinct from attempting to maximize bandwidth utilization or to minimize long-term transport-layer overhead. In determining DTP's features and formats, uppermost was the consideration of how to define the protocol to minimize the RTT between transmission of a reliable message and its acknowledgement. ZERO-COPY PROTOCOL STACKS AND CHECKSUMMING A primary source of overhead in protocol processing can be attributed to operations that read and/or write all, or most, of the bytes in a packet. Examples of these operations are (1) digest or encryption security functions, (2) buffering and copying between different protocol layers (network -vs- transport) or implementation layers (application -vs- operating system), or (3) data fidelity checksum algorithms. A protocol implementation that eliminates those per-byte costs is referred to as a zero-copy protocol stack; the ability to perform a particular operation without the per-byte overhead is a zero-copy operation. We are concerned about checksum functionality, and mechanism to support zero-copy checksuming in the next-generation TCP/IP protocol stack (IPv6, TCPv6 and UDPv6). The principal advantage of a zero-copy stack is increased performance. A 20MHz Myricom LANai interface processor can scan application buffers for a packet to send, prepare that packet, transmit it with CRC and service a send-done event in 51 machine instructions. As a result, a source application running on a Cooper [Page 15] Internet Monthly Report February 1995 SPARCstation-10 can send IP/UDP RPCs individually, at a rate of 70K/second across the network into a destination application. This performance is a result of (1) a shared-memory interface between application and network interface, and more importantly (2) the use of the zero-copy link-layer checksum provided by hardware interface. Only in cases where both the source and destination nodes are on the same LAN can end-to-end data protection can be provided by a link-layer checksum, rather than a combination of network and transport checksums. A high level of performance is possible because packets are not copied and neither the network layer nor the transport-layer need to scan them to calculate checksums. However, this zero-copy technique does not easily extend to cover situations where source and destination nodes are on different LANs. This sharply restricts the domain within which the better performance is available. Greg Finn <finn(a)isi.edu, Steve Hotz, <hotz(a)isi.edu, Bruce Parham, <Bparham(a)isi.edu>, Vivek Goyal <goyal(a)isi.edu> ATOMIC-2 ======== This month the ATOMIC-2 project completed Web pages, available at: <http://www.isi.edu/div7/atomic-2> Everything in this and coming reports will be available on-line in these web pages. Work continues on the following topics: LAN Installation Applications Demonstration File Server Applications Bandwidth Next month we will have additional information on ATOMIC-ATM Gateway ATOMIC Interface Design ATOMIC-2 LAN INSTALLATION This month the ATOMIC LAN replaced the Ethernet connection on three office workstations (Sun SPARC 10/41, 10/51, and 20/50) at ISI. The Ethernet to these hosts is completely disconnected, and they have been running continuously for three weeks. They are currently gatewayed through a Sun SPARC-2 to the division Ethernet, including the MBONE. This will be replaced with the ATM gateway under Cooper [Page 16] Internet Monthly Report February 1995 development. We expect that over the next two months a total of 65 workstations will be on the ATOMIC LAN, and the Ethernet will exist to support only those hosts for which Myricom interfaces have not yet been implemented. ATOMIC-2 APPLICATIONS DEMONSTRATION PVM (Parallel Virtual Machine) [1] supports distributed and parallel computing applications. PVM 3.3 has been installed on the ATOMIC LAN. We measured the communication bandwidth and latency between two PVM tasks on this LAN, between two Sun SPARC 20/50 hosts. The task-task latency has a 1.15 ms overhead (of which 0.7 ms is ATOMIC LAN overhead), the remainder determined by the packet length and bandwidth. The bandwidth is 25-30 Mbps for 2 Kbyte packets, and drops to 10 Mbps for 0.5 Kbyte packets. TCP can reach peak bandwidth 50 Mbps in the ATOMIC LAN, the PVM's peak bandwidth is lower due to the extra memory copy between the PVM buffer and user data buffer. In order to explore the high ATOMIC link-layer bandwidth and avoid the kernel protocol stack overhead, our next step is to improve PVM performance by implementing PVM message passing routines using the Myrinet API, instead of TCP. [1] Geist A. at al. "PVM 3 User's Guide and Reference Manual", Oak Ridge National Laboratory, Sep., 1994. ATOMIC-2 FILE SERVER We are continuing our investigation of NFS performance, in order to determine the ATOMIC-2 File Server design. Our measurements indicate that NFS write bandwidth is bounded by both the Sun RPC protocol that commonly implements it, and internal interactions with the BSD file system. RPC limits the bandwidth because only a single request/response can be outstanding to any given process. Sun's implementation of NFS uses multiple processes to effectively overcome this limitation on an Ethernet. On the higher bandwidth ATOMIC network, the overhead of context switching and demultiplexing packets to these processes limits the bandwidth to less than observed TCP or UDP user-user bandwidth. Essentially, the low bandwidth solution is bottlenecked in comparison to the high bandwidth network. We believe it would be more efficient to have a single process fill a sliding window than use multiple processes doing RPC. The BSD file system also interacts with NFS, particularly when writing disk blocks. When a file is read, then a request for the Cooper [Page 17] Internet Monthly Report February 1995 block the user is interested in is issued immediately, potentially along with several read-ahead blocks. This pattern is fairly predictable, and maps closely with the read calls that the user makes. When a disk block is written, it is written to the BSD file cache, and flushed out to the server when the paging system needs one of the disk cache pages, or notices that the page has been dirty for some time. A block written by a user can sit in the file cache for some time before the page daemon flushes it to the server. Furthermore, the paging daemon and the user writes are entirely disconnected; the pattern of writes the user issues and the order and timing of the blocks that are flushed to the server by the page daemon are basically independent. The combination implies that it is harder to pipeline write requests than read requests. (There are good reasons to cache file writes, notably not bothering the server with writing short-lived temporary files, but it impacts NFS performance as well.) We are investigating strategies to both implement NFS using a higher bandwidth transport protocol and to pipeline writes more effectively. ATOMIC-2 APPLICATION BANDWIDTH ACCESS EXPERIMENTS Previously most of the performance measurement tools in use on the Atomic-2 project have made use of the standard SunOS API, the socket interface, which provides user programs access to TCP/IP and UDP/IP. To develop an understanding of how bottlenecks might be avoided, some of these applications are being augmented to optionally use the Myrinet API, which will allow the user program to send raw Myrinet packets and bypass the kernel. Using a pre-release version of Myricom's dual-path driver, the IP traffic and Myrinet API traffic have been able to run simultaneously on the ATOMIC LAN. The performance of running simultaneous IP and API traffic is critical in assisting our high- performance protocol research. In our experiments, the IP traffic and API traffic were running in the same direction between two Sun SPARC 20/50s connected through one 8-port switch. We found that the performance dropped by 10-30%, even though we were running only one type of traffic at a time through the dual-path driver. single-mode dual-mode driver driver ----------------------------------------------------- Native API packets 220 Mbps 150 Mbps UDP/IP 60 Mbps 54 Mbps TCP/IP 50 Mbps 44 Mbps Cooper [Page 18] Internet Monthly Report February 1995 Two possible reasons for the decrease in throughput are additional overhead due to interface demultiplexing and lack of sufficient buffer space (because the space is fragmented into two packet queues). ATOMIC-2 SECURITY Last month the performance analysis of MD5 was completed. This month we began analysis and selection of alternatives that can support ATOMIC LAN bandwidth. This analysis is proceeding with MD2. Initial analytical results indicate that MD2 should run 20 times slower than MD5, which is too slow for the ATOMIC LAN (38 Mbps on a SPARC 20/50, where UDP is 50 Mbps). Measurements indicate that the current optimization of MD2 runs 30 times slower than MD5; because a speedup of only 50% is possible, this work is not being pursued. We are instead evaluating other authentication algorithms more suitable to high-speed implementation in software and/or hardware.

Most of these suggestions dealt with the portability of the code. The most extensive of these came from MIT which ported RSVP to DEC alpha machines and Intel based PC's. These changes allow RSVP to run on 64 bit architectures such as the alpha and "little-endian" machines such as the PC and the alpha. We are testing the interoperability of these versions. Other input came from Bill Nowicki at Silicon Graphics who was porting RSVP to SGI machines. Another remaining issue for the complete version 1 RSVP is the support of tunnels. Such a tunnel exists between the Xerox PARC DARTnet router and most of the PARC hosts. We are using UDP encapsulation on a well-known multicast IP address to communicate between hosts and routers.

Merit has sent a 60-day termination notice for the NSFNET Backbone Service to ANS. The backbone ENSS's will be turned off at midnight on April 30 in each respective time zone. Merit and the regionals have enjoyed a successful collaboration for many years, and we look forward to continued joint successes in the brave new world of post-NSFNET! Many regionals are obtaining interregional Internet service from Network Service Providers, and have moved off the T3 NSFNET backbone. Merit will now gradually discontinue the T1 "safety net" that has backed up regional connections to the T3 NSFNET for several years. The Routing Arbiter Project's Route Server at MAE-East has begun to pass actual routes to its peers. Among the AS's receiving routes are MCI, PIPEX, and Net 99. Many thanks to these AS's for helping move the new technology along! Merit has ported PGP version 2.6 into the RIPE routing registry software. The new privacy feature makes it possible to use PGP's popular cryptographic algorithm to authenticate data submitted through e-mail to the Routing Arbiter Database (RADB) and other Cooper [Page 24] Internet Monthly Report February 1995 RIPE-181-style registries. To implement PGP, simply enter 'PGP- FROM my.email.address' in the RADB Maintainer object's 'auth:' field. You then use a public domain PGP client to sign your e-mail with your secret key. The RADB software uses your public key to verify your signature. The PGP encryption schema is known to be very difficult to break. PGP can also provide confidentiality by encrypting any data in such a way that only the recipient can read the message. For more information, contact Laurent Joncheray at Merit (lpj(a)merit.edu.) As part of the process of replacing the NSFNET Policy Routing Database (PRDB) with the RADB, the RADB has been populated with RIPE-181-style Maintainer and AS Objects for all Autonomous Systems known to the PRDB. NACRs are now being checked against this information rather than the PRDB. In addition, the list of contacts who are authorized to submit NACRs has been moved to the RADB. The NACR contact data has long been queryable using the old command: whois -h prdb.merit.edu 'contact <AS_number>' Now when you issue that command, you receive as output the RADB Maintainer object that includes your contact information, along with a message explaining how to update the Maintainer object. The following new command is equivalent and produces the same output: whois -h whois.ra.net 'MAINT-AS<AS_number>' For AS690, you would type: whois -h whois.ra.net MAINT-AS690 Similarly, network data has long been queryable using the old command: whois -h prdb.merit.edu '<net_number>' Now when you issue that command, you receive as output the RADB Route object that describes that network. The new, equivalent command is: whois -h whois.ra.net <net_number> During the next phase of the PRDB --> RADB transition, the two databases will run in parallel, and NACRs will be used as input to both the PRDB and RADB. In the final phase, users will be able to submit RIPE-style Route objects instead of NACRs. For further information about the PRDB --> RADB transition, see Cooper [Page 25] Internet Monthly Report February 1995 ftp://ftp.ra.net/pub/radb/OVERVIEW and ftp://ftp.ra.net/pub/radb/doc/updating_maintainers. Jessica Yu of Merit has been working with ISI's Cengiz Alaettinoglu to extend RIPE-181 to specify AS path expressions in routing policies. Merit's Andy Adams and Alaettinoglu are modifying RtConfig, a router configuration tool, to generate configuration files supporting these extensions. Merit has received a continuation of FAA funding for its joint government/industry IDRP project, which is managed by the MITRE Corporation. Merit's effort is led by Sue Hares, who co-chairs the IETF Inter-Domain Routing Working Group. The project's Gated-IDRP version 1.1, which supports advanced policy descriptions, is expected to be released in April. In the next phase of the project, Hares and other Merit staff will implement a mobile Boundary Information System in IDRP. Under a grant from NSF, Craig Labovitz continues development of the Multi-Threaded Routing Toolkit (MRT), which provides a simple, extensible platform for developing and debugging routing protocols and routing code. The Toolkit comprises a set of generic libraries that can be used to build small executables and scripts that perform complex routing tasks quickly and efficiently. The MRT architecture uses the multiple-thread technology available in the Sun operating system to take full advantage of the speed and power of multi-processor machines. For more information, contact Labovitz at labovit(a)merit.edu. Westnet and NCAR hosted the third North American Network Operators' Group (NANOG) meeting in Boulder, Colorado, on February 9-10. Stan Barber of Academ Consulting Services has kindly made available a complete set of notes and slides from the meeting. They are available at http://www.academ.com/nanog and at Merit's Web site, http://www.ra.net/rainfo.html. Elise Gerich of Merit moderated the meeting, which featured the following presentations: --Transition Updates from ANS (Guy Almes), internetMCI (Jack Waters), SprintLink (Sean Doran), BARRNET (Vince Fuller), UNIDATA's Internet Data Distribution Service (Mitch Baltuch), NorthWestNet (Steve Corbato), CERFnet (Pushpendra Mohta), MichNet (Bert Rossi), and CA*NET (Eric Carroll) --InterNIC Update (Mark Kosters, Network Solutions, Inc.) --Chicago NAP Update (Mark Knopper, AADS) --ATM Testbed Status Reports from Kentrox (Rolf Hahn and Cooper [Page 26] Internet Monthly Report February 1995 George Shenoda), AADS (Eric Bennett), PacBell (Kent England), ANS (Curtis Villamizar), and the vBNS project (Dennis Ferguson, MCI, and Matt Mathis, Pittsburgh Supercomputer Center) --Network Management Tools for ATM PVC Topologies (Taso Devetzis, Bellcore) --DANTE Overview (Michael Behringer) --CIDR/Aggregation/Allocation Policies (Sean Doran, SprintLink) --Route Flap Problem Overview (Sean Doran, SprintLink) --MAE-West Update (Milo Medin, NASA Ames Research Center) --Route Flap Damping Algorithm (Curtis Villamizer, ANS) --Route Server Status (Yakov Rekhter, IBM) --PRDB --> RADB Transition (John Scudder, Merit) --Route Security Issues (Sean Doran, SprintLink) Susan R. Harris (srh(a)merit.edu) MIDNET ------ MIDNET INTRODUCES "A PRACTICAL GUIDE TO THE INTERNET" SEMINAR MIDnet's first "Practical Guide to the Internet" seminar was held during February.The goal of the seminar was to introduce newcomers to the advantages of the Internet through real-world examples, and to remove the mystic of the Internet by providing information in layman's terms. The seminar was well attended, with an audience that consisted of representatives from both the business and educational communities. Plans are currently underway to offer this seminar in additional locations within the MIDnet region. MIDNET MEMBER MEETING During February, MIDnet representatives met with a state educators to determine their Internet needs and goals. The meeting was attended by representatives from K-12 as well as representatives from institutes of higher education. MIDnet provided information on the current state of its network in conjunction with the NSF transition, and distributed a document which described and provided pointers to Internet resources of particular interest to educators. MIDNET'S INTERFACE TO POPULAR INTERNET RESOURCES Activities are underway to expand the number of resources accessed via MIDnet's WWW server. Resources currently enjoying popularity include the Net-Happenings Mail List and Diane Kovac's Directory of Scholarly Electronic Conferences, for which MIDnet provides a WWW view with search and browse capabilities. MIDnet's NIC has Cooper [Page 27] Internet Monthly Report February 1995 identified two additional Internet resources which provide valuable information to the Internet community. Agreements are currently being drafted which will allow MIDnet to implement its interface to these resources. MIDnet NIC <info(a)mid.net> UCL ---- The major event of the last month was the setting up of a 4 nation demonstration of IP Mbone based multimedia conferencing ofver the PNO trial. The PNOs (Public Network Operators) of the EU (European Union) have provided a trial 34Mbps ATM network for the current year for research projects such as MICE. We configured a set of mbone suns and Ciscos to use this between INRIA in france, the G7 summit meeting in Brussels, RUS in Germany and UCL in London. The configuration has been reported elsewhere, and a detailed report on the setup and performance will be available fairly soon. A draft is available on request from J.Crowcroft(a)cs.ucl.ac.uk, however, the hypotheses we have formed about what worked and what didn't are not completely proven yet. Suffice it to say for now that it was a major success, using just about every piece of networking technology anyone could think of. The net ran uninterrupted (and unsupported) for 3 days, with only the partial failure of an ATM/SMDS interworking unit dropping one site off the demo about half way through. There are some interesting lessons for how IP and Internet based applications have to be configured to run this, and over the next 3 months, we shall be experimenting further to get a better scientific confirmation of our hypotheses noted above. Also, 2 papers were submitted to ACM SIGCOMM '95.

INCOMING: IP Provider Metrics
by Matt Mathis 15 Mar '95

15 Mar '95

Attached is my initial cut at an agenda and some introductory discussion for the upcoming IP Provider Metrics BOF at Danvers. I plan to circulate this to the main IETF list on Friday. Even though I am going to work hard to prevent it, this is likely to become quite political. My intent is to provide tools and methods (standard procedures) which will enable the market to reward providers who are true to their mission, what ever that may be. Although my historical point of view has always been in the operations community, I have clearly become "just a customer". Furthermore, there is a large pool of "experts" who think that they can do the job better than you. Therefor, it is crucial that current providers take an active role in this effort, if nothing else to offset the "experts". Comments are welcome. Thanks, --MM-- Draft agenda of the "IP Provider Metrics" BOF 6:00 - 11:30 Wednesday, April 5, 1995 ============================================= Consider a possible WG. (15 minutes at opening) * - Is a new WG needed? * - Relationship to BMWG/GISD/others - Inventory of possible tasks - Requirements for IP Provider Metrics * - Define scope and priorities * - Chair issues, Editor/secretary * - Charter (* introduce at the open, but postpone detailed discussion until the close) General Requirements for IP provider metrics (15 min) IP bulk data transfer performance (technical issues, 30 min) IP routing stability and robustness (technical issues, 30 min) Consider a possible WG...., part 2 (30 min) ---------------- Rough Draft Charter IP Provider Metrics (IPPM) The IPPM WG will develop a set of standard metrics that can be applied to the the quality, performance and reliability of an IP datagram service. These metrics will be designed such that they can be performed by the providers themselves, customers, potential customers or independent testing groups. The areas covered will include: I) Path Performance A) Bulk data transfer performance (ftp, etc) B) Interactive performance (Telnet, X11, etc) C) Real-time and multicast performance (delay statistics) II) Routing stability and robustness A) End to end availability B) Time to recover (e.g. switch to backup paths) C) Route stability (Spurious route transitions, etc) III) others TBD The IPPM WG will select or adapt existing tools and develop standard procedures for performing and documenting the measurements. ---------------- Notes on the Charter o Services peripheral to basic IP, such as NOC/NIS services, DNS, etc. are expressly excluded because there is vehement anti-consensus among Internet providers. Prior efforts to standardize these areas have failed because they impinge on the different business models held by the providers. For example some providers include full, high quality DNS service bundled with their IP service. Others provide inexpensive DNS "starter" services, but expect most customers to eventually run their own servers. o It is also important that the language not be pejorative, to permit providers to strategicly balance their price and performance. We want to encourage all market positions including "Inexpensive, good enough service" as well as "The best possible service". o The milestones will be weighted to address I.A. (bulk performance) and possibly parts of II first. The other goals will be addressed as an ongoing effort. The scope will start very narrow, and will be extended only as we have assured closure on the initial tasks. o I have a prototype bulk transfer diagnostic that can safely and accurately measure IP bulk performance. It is a combination of traceroute and Reno TCP, and can provide traceroute like path information under exactly the conditions induced by TCP. See the discussion below. o The difficulty with routing stability metrics, is that the best ones require collusion with the Internet providers themselves. This clashes with the provider-to-provider trust model that is a necessary for healthy operation of the Internet as a whole. BGP can easily be used to collect engineering, business and other data on competitors. I believe that there exists a good technological solution based on the global collection and archiving of sanitized BGP logs. Clearly, there is a substantial piece of this technology that belongs with the RA and other global routing agents. However, there are also parts that belong to the community in the form of a working group. There needs to be a discussion of the possible role for IPPM in this process. o The IETF is not "poised" to address "standard measurement procedures". Is this a problem? o The final draft of the charter should be completed after the WG is convened. o IPPM should have an editor other than the chair. ---------------- Comments on the bulk performance tool: I am working on a prototype diagnostic tool ("treno") designed to address bulk performance issues. It is derived from Windowed ping (Matt Mathis, INET'94, See ftp://ftp.psc.edu/pub/net_tools/WPing.ps) but designed to be safe for typical network administrators at user sites. It uses traceroute to emulate Reno TCP over any IP infrastructure. This approach has a number of strong advantages: - Its bandwidth consumption is bound by the same congestion mechanism as TCP. (Although this is more than might be tolerated for ongoing monitoring). - It measures the network under the same queue dynamics as inflicted by TCP. - Differences in the end systems need not affect the results. - Today it can identify the lowest performance provider in a long path if there is a suitable unix box near each interconnect. - Someday it will be able to diagnose (to a specific hop) any path across the Internet. Treno is not yet completed. There are some open issues which can best be addressed as part of an IETF WG, with open and public input from all interested parties. In the end this will make it a stronger tool for supporting the growth of the Internet. Incomplete Tasks: - Certify that treno emulates Idealized Reno TCP. Understand and evaluate the implications of differences between treno and Reno as it appears in the field. (IPPM and end2end research community) - Develop testing methodology for "data sheet" measurements: How to select and specify endpoints, sampling schedule, etc for measuremets to be used on a "data sheet" or service level language in a contract. (IPPM and the network operators community) - Document the need and utility for all router vendors to support full rate ICMP TTL exceeded messages. (IPPM and RREQ?)

First ENSS retired
by Elise Gerich 14 Mar '95

14 Mar '95

The first router of the NSFNET backbone service has been retired. ENSS 138 (in Atlanta, Georgia) was retired on March 11, 1995. It was a pleasure working with Georgia Tech and SURAnet to provide connectivity to the NSFNET Backbone for that part of the US. One down. --Elise

Rescheduled configuration window
by epg＠merit.edu 14 Mar '95

14 Mar '95

This morning at about 03:00 EST, Merit discovered that many of the configuration files which were to be distributed to the NSFNET Backbone were incorrect. There was insufficient time to regenerate all the files and propogate them throughout the backbone in time for the Tuesday morning configuration window. The configuration window was postponed until Wednesday morning. Unfortunately, we neglected to notify the broader community about this problem, so many folks have been worried about what happened to their configuration changes or additions. The new configuration files will be deployed Wednesday morning. --Elise
