If the peer is already working on processing the old ones, this adds an unneeded burden on the regional peer. I have not reviewed the spec in detail, but there should be something in place to prevent a constant cycle of close, open, slam 5k routes, close, open, slam 5k routes, close... well, you get the picture. This points out a configuration problem with BGP in the ANS T3 routers, in addition to the less than optimal configuration that we had in our ciscos. Just my two cents from the other side of the fence. -- Regards, Bill Manning bmanning(a)rice.edu PO Box 1892 713-285-5415 713-527-6099 Houston, Texas R.U. (o-kome) 77251-1892

RS/960 upgrade on the T3 backbone: status report
by mak 01 May '92

01 May '92

Phase-III RS960 Deployment Status Report - Week 1 ================================================= Jordan Becker, ANS Mark Knopper, Merit Summary ======= - RS/960 Hardware Deployment Early last Saturday morning, April 25, the first step of the Phase-III RS960 DS3 upgrade to the T3 Backbone was completed. The following T3 backbone nodes are currently running with new T3 hardware and software in a stable configuration: Seattle POP: CNSS88, CNSS89, CNSS91 Denver POP: CNSS96, CNSS97, CNSS99 Regionals: ENSS141 (Boulder), ENSS142 (Salt Lake), ENSS143 (U. Washington) This Friday night 5/1 and Saturday morning 5/2, the second step will occur, with the following nodes being upgraded: Los Angeles POP (barring rioting, etc.): CNSS16, CNSS17, CNSS19 San Francisco POP: CNSS8, CNSS9, CNSS11 Regionals: ENSS128 (Palo Alto), ENSS144 (NASA Ames/FIX-West), ENSS135 (San Diego) - Kernel Build and Routing Software Deployment Early this morning (April 30), all of the network nodes were upgraded with Build 2.78.22 and a new version of rcp_routed. Several nodes (the Step 1 nodes and also the Ann Arbor ENSS) have been running in this configuration since April 27. This software build includes drivers for the RS/960 cards, and several bug fixes. The fixes include reliability improvements to the FDDI software, notably a soft reset for a hung card; and some additional improvements to the T960 ethernet and T1 card support to fix a problem where the card could hang under a heavy load. The rcp_routed change includes a fix to a problem that was observed during RS/960 testing. The problem involved some aberrant behavior of rcp_routed when a misconfigured regional peer router would advertise a route via BGP to an ENSS whose next hop was the ENSS itself. The old rcp_routed could go into a loop sending multiple redirect packets out on to the subnet. The new rcp_routed will close the BGP session if it receives an announcement of such a route. The new rcp_routed software also has support for externally administered inter-AS metrics, an auto-restart capability, and bug fixes for BGP overruns with peer routers. This deployment caused a few problems. One is that this new feature of rcp_routed pointed out a misconfigured peer router at Rice University in Houston. This caused the BGP connection to open and close rapidly which caused further problems on the peer router. Eventually the peer was reconfigured to remove the bad route, which fixed the problem. Another problem was on the Argonne ENSS. This node crashed in such a way that it was not reachable and there was difficulty contacting the site to reboot the machine. Once the reboot was done the ENSS came back up running properly. We are looking into the cause of this crash, as this is the first time this has happened in all of our testing and deployment. The third problem was at the CoNCert ENSS, and this node crashed in such a way that the unix file system was completely lost, and this requires a complete rebuild of the system. This problem has happened in two cases previously, and seems to be related to an AIX problem rather than anything in the new software build. It is an insidious problem since it completely wipes out any trace of what may have caused it. We continue to look into this. In our view, none of these problems are severe enough to call off the deployment of the RS/960 hardware upgrade on the west coast Saturday morning. These problems aren't related to the new hardware or software support for the new cards, but seem to be problems in other parts of the new software build or routing daemon. The following section details our experiences of the first week's deployment. We believe we have an understanding of the problems that occurred and have increased the number of spare cards in the kits that the teams will take out to the sites. Summary of Week 1 (beginning 4/25) RS/960 Deployment ==================================================== Since the deployment, nodes CNSS88 and CNSS96 have been running with mixed technology (i.e. 3xRS960 T3 interfaces, 1xHawthorne T3 interface). Production traffic on the affected ENSS nodes was cutover to the T1 backbone at 2:00 AM EST on 4/25. The Denver POP nodes were returned to full service after approximately 10.5 hours and Seattle after about 13 hrs of work. The new software had been deployed on the affected nodes during the prior week. The physical upgrade consisted of mechanical changes to the RS6000 machines including (1) replacement of the RS6000 I/O planar, (2) replacement of the Hawthorne T3 adapters with RS960 adapters, (3) upgrading the DSU hardware and associated cabling, (4) a modification of the cooling capabilities of the RS6000, (5) updating and standardizing on new labels and (6) local software configuration changes accommodating the use of new hardware. The nodes were then tested and returned to production service. Although the resulting configuration is very stable and gratifying to the team working on the upgrade, the process was not quite as smooth as had been expected. There were 33 RS960 T3 interface adapters, T3 DSUs, and 9 I/O planars installed. Out of these, 5 RS960 adapters and 2 I/O planars had to be replaced to achieve stability. The failing new components were air-shipped back to the staging lab for a complete failure analysis. and a summary of the results are described below. All of the problems involving replaced components have been identified or explained. The post-manufacturing burn-in and staging process consists of a stress test involving card-to-card traffic testing, DSU testing, and power cycling prior to shipping. Lab burn-in and staging procedures have been adjusted based upon our experiences with the first deployment step. The installation procedures will be fine tuned to improve our efficiency and reduce the installation time required. It is therefore our intention to continue with the step 2 deployment plan in the San Francisco and Los Angeles backbone nodes (and adjacent ENSS nodes) on Friday evening 5/1. Installation Problems Encountered ================================= The replacement of the RS6000 I/O planers had to be performed twice on nodes CNSS88 and CNSS91 after the nodes did not come up properly the first time. The original set of planers were returned to the lab for analysis. It was determined that the underside of the planars were damaged during the physical installation process. The procedure for installing these planars in the RS6000 model 930 rack mounted system has been modified to prevent this type of damage from occuring. Adapter re-seating and reconfiguration was required on the asynchronous communications adapter on CNSS89. The dual planar change and troubleshooting work adversely affected the hard disk on CNSS88 and the disk image had to be reloaded from tape. An apparent dysfunctional DSU HSSI card connected to CNSS97 was replaced and was returned for lab failure analysis. The analysis revealed that a DSU microprocessor was not properly seated. T3 Technologies will re-inspect the DSUs for proper seating of all DSU components. The DSU at ENSS142 (Salt Lake City) needed internal work. The analysis revealed a bent pin on the connector between the HSSI card and the DSU backplane. T3 Technologies Inc. (DSU manufacturer) identified a mechanical deficiency in the connector that can cause certain pins to loosen and bend during insertion of the card. T3 Technologies will add a procedure to inspect these connectors prior to shipment for any deficiencies. An RS960 T3 card in CNSS89 did not have the correct electrical isolation spacers installed, and this caused a temporary short circuit. The card was returned to the lab and it was determined that a last-minute change was made to the card to swap an i596 serializer chip and that the spacer was erroneously left off. A visual inspection procedure for spacers and standoffs will be added to the manufacturing and staging inspection process. The RS960 T3 card in CNSS97 came up in a NONAP mode, however the card continued to respond to DSU queries. The card was replaced. During the failure analysis, the card passed all stress tests. This card was swapped prior to a planar change and the NONAP mode has been attributed to the planar problem. When reliable connectivity could not be achieved between CNSS97<->ENSS141, another RS960 T3 card in CNSS97 was replaced. The lab failure analysis revealed that the 20Mhz oscillator crystal on the card was broken due to a mechanical shock. This shock could have occured during shipping or handling. CNSS91 rebooted after the upgrade and exhibited an unstable configuration. Both the I/O planar and the RS960 T3 card were changed before stable operation was achieved. The RS960 card was later found to have a cold solder joint between the RAM module and adapter. The solder joint would allow the card to work when cold, but would fail intermittently when running hot. A simple adapter thermal cycling procedure will be investigated to determine if this problem can be avoided in the future. CNSS88 was the last node to come up. The I/O planar and memory card had to be re-seated, and an RS960 T3 card replacement was necessary. The RS960 card was found to have a solder splash that was overlapping two adjacent pins. A general corrective action for this problem involves adding a procedure involving high magnification visual microchannel interface inspection for shorts. Conclusions =========== Although the Step 1 installation was complicated by several component problems, the entire deployment team (IBM, Merit, ANS, MCI) has a high comfort level with the results of the failure analysis, the stability of the resulting installation, and overall deployment process. We are very encouraged that we have completed this first step and acheived a very stable configuration within the time, human resources, spares and support that was provisioned as part of the deployment plan. The software bring-up and test scripts worked exactly as planned. The teamwork between the 50+ individuals involved at Merit, IBM, MCI and ANS was excellent. The basic installation process is sound, although some minor changes will be implemented in the future installation steps. These will include the RS960 adapter installation, DSU trouble-shooting procedure and the I/O planar change process. Also the number of spares provisioned in a deployment kit will be increased as a pre-caution for future installations. There has been one software problem identified with the new technology on the test network since the end of system testing on 4/17. This involves a microcode bug where a portion of the RS960 on-card memory will not report a parity error to the system if that portion of the memory suffers a failure. All RS960 on-card memory is tested prior to shipment and a microcode fix to this problem will be delivered by IBM for testing within the next week. Only a single RS960 adapter has demonstrated an on-card memory parity error during all test network testing. Next Steps ========== Step 2 of the deployment is currently scheduled to commence at 23:00 local time on 5/1. Step 2 will involve the following nodes/locations: May 1/2 San Francisco, Los Angeles core nodes T3 ENSS Nodes: Palo Alto E128, San Diego E135, Other ENSS Nodes: E144, E159, E156, E170 also affected Second core node visit: Seattle

Transition of ICM NOC from Cornell to Sprint
by rcollet＠icp.net 26 Apr '92

26 Apr '92

In January of 1991 Sprint entered into a cooperative agreement with the National Science Foundation to provide International Connections Management (ICM) to NSFNET. The international network service is called ICMnet. As part of the Sprint Team Cornell University provides the ICMnet Network Operations Center (NOC). Sprint and Cornell University have mutually agreed to the transfer of NSF ICMnet NOC duties to the SprintLink Public Data Internet (PDI) NOC. Sprintlink, which provides "acceptable use" and "commercial" nationwide IP routing services, is now operational. The consolidation of ICMnet functions with SprintLink will streamline operations and eliminate duplication of effort. The precise cut-over schedule, points-of-contact list and other associated information will be distributed within two weeks. Cut- over of individual links is tentatively scheduled for mid May. I would like to thank Cornell University for their hard work and superior performance. Their dedication has yielded an international network with an enviable record for availability and stability. In particular, I would like to recognize Mark Oros for his focused efforts in implementing a well-managed, responsive NOC. If there are any questions concerning the transition please use the following. Bob Robert D.

Phase-III Deployment Status Update ================================== Jordan Becker, ANS Mark Knopper, Merit The phase-III deployment schedule involving the replacement of "Hawthorne" T3 interface adapters and DSU cards in the RS/6000 T3 routers is progressing on-schedule. We have completed our system testing and are conducting on-going regression tests on the test network (recent testing and upgrade activies described below). Pending any un-foreseen problems that come up, the hardware upgrades will begin on Friday 4/24 at 23:00 local time at the Seattle CNSSs, Denver CNSSs, Seattle ENSS143, Boulder ENSS141, and Salt Lake ENSS142. In preparation for the upgrade, we have been making software changes to the production T3 system in advance to support the hardware upgrades that are scheduled to begin on 4/24. These changes include a new system software build that supports the RS960 drivers, kernel, and microcode. We are also installing a new SNMP program that support the new c-bit parity DSU function, and several bug fixes for existing FDDI and T960 ethernet freeze problems. The proposed maintainance window for these network software upgrades is as follows: 1. 4/21 at 12-1am EDT: Install build 2.78.22 on Seattle CNSS's 88, 89 and 91; Denver CNSS's 96, 97, and 99; University of Washington ENSS 143; Boulder ENSS 141; and Salt Lake ENSS 142. (done) 2. 4/22 at 6am EDT: Install build 2.78.22 on San Francisco CNSS's 8, 9, and 11; Los Angeles CNSS's 16, 17, and 19; Palo Alto ENSS 128; NASA Ames/FIX-W ENSS 144; and San Diego ENSS 135. With the cutover of traffic from T1->T3 of FIX-W, Westnet-E, CICnet, NCAR and Midnet in the last 2 weeks, we will halt any additional regional traffic cut-overs until after the phase-III upgrades are stabilized. We are in the process of contacting each regional individually to discuss the upgrade and what you can do to help us ensure that this goes as smoothly as possible. We will be requesting coordination with regionals in the use of the T1 backbone as backup to the T3 system during different points in the upgrade schedule. This may require employing emergency procedures such as disabling AS peer sessions to the T3 backbone on some regionals if we run into trouble (not that we anticipate that, since we are confident that testing has been very thorough). During the upgrade schedule, there will be a growing router cloud that supports the RS960 T3 technology and a shrinking router cloud that supports the Hawthorne T3 technology. We have designed the interface points between these clouds to try and minimize traffic flow across them at any give time since the T3 system is carrying considerable traffic and these "hybrid links" represent a potential performance bottleneck. A internal T3 routing link metric assignment plan is being generated to minimize Hawthorne-cloud to RS960-cloud traffic (by assigning an increased metric to selected T3 hybrid links). We are performing an AS-AS regional traffic simulation to design these internal link metrics in an way that balances traffic flow across the T3 system and avoids over-loading of the hybrid links. We have already done some initial experimentation with different link metrics and validated the results. These link metrics will be changed manually by our engineers at different points in the deployment process to spread the load across the hybrid links and thus minimize load on any single hybrid machine. An appendix to this message contains some more information on metric adjustments and how these were determined and verified. This work is credited to Elise Gerich of the Merit IE group. We would like to develop a procedure and plan with each regional for cutover to the T1 backbone during scheduled periods, and during possible unscheduled periods in the event that a hybrid link should get too close to saturation. We would like to coordinate a plan where our engineers maintain a pre-designated list of T3 ENSS nodes in each phase of the deployment that get configured down (off-line), in conjuction with a regional switching their routing over to divert traffic to the T1 backbone. Phase-III Technology Testing Status =================================== Since our last update on phase-III deployment testing, we have closed several problems that were identified and we will continue to regression test up to and during the deployment, and maintain a scaled down replica of the T3 system configuration on the T3 research network during the deployment. This will allow us to continue testing and support any needed tests for problems that may be identified during the deployment. Since the last report, we have been focusing our test efforts in the following areas: 1. Regression tests for bug fixes in the current T3 system. We have fixed several bugs in the current production T3 network FDDI driver, T960 ethernet/T1 interface driver and associated microcode. These fixes have been merged into the production RS960 system software build scheduled for deployment this week and have been regression tested. 2. Stress testing of the new build. We have corrected an earlier problem we were experiencing with a test tool that copies all production ethernet traffic with a new destination address onto the T3 Research network to simulate real production network traffic flows. This so called "copy tool" is working on the test network and has been a major component of our stress testing. 3. Full RS960 (4 interface) configuration testing. We have focused much of our testing over the last couple of months on the mixed technology configurations (e.g. Hawthorne T3 adapters and RS960 T3 adapters co-resident in the same router and network) since we were most concerned about the actual deployment process. We have most recently tested the full RS960 (4 interfaces in a CNSS) configuration which we are less concerned about. 4. FDDI peering tests. We have tested ENSS configurations that include an FDDI interface and an RS960 T3 interface that peer with with 2 FDDI equipped Cisco routers. 5. Noise injection testing on T3 lines. We have tested noise injection on the T3 test network circuits with the aid of a test tool provided with the T3Plus Inc. BMX45 bandwidth manager. The results of these tests demonstrated a T3 technologies DSU problem involving SNMP sub-agent signalling. We have addressed this problem for now with a change to the SNMP sub-agent. A PROM change to the DSU will be installed at a later date to avoid any additional SNMP sub-agent overhead required to address this problem. Noise testing on the research network is ongoing, in an attempt to find additional problems during stress and other traffic load tests. 5. T3 routing software testing. One of the tests that we have always wanted to conduct on the T3 Research network is the simulation of 60+ internal routing peers that generate IS-IS LSPs which most accurately mimics the production T3 network. We never had enough nodes on the T3 Research network to generate more than 10 of these internal IBGP peer sessions before. We are now testing with a modified version of our routing software that generates multiple IBGP internal sessions so that we can simulate internal IS-IS routing exchanges with several more internal peers. This will improve our routing software test environment now and in the future. 6. T3 routing software enhancements. There are several new enhancements to the T3 routing software that we have tested with the RS960 technology including an auto-restart function in the event of a daemon failure, BGP version negotiation support, and correct support for the interpretation of inter-AS external metrics. These software changes are independant of the phase-III deployment and will be scheduled for deployment during a maintainence window that does not interfere with the phase-III deployment activities. Other Activities Related to RS960 Deployment -------------------------------------------- NOC training - The NOC requires well documented debugging procedures that operators can understand and execute without problems. This includes new man pages from engineers on RS960 utilities and commands (e.g. ifstat, ccstat, etc.). A disaster recovery procedures checklist has been drafted that includes information on how to recover from problems during and following the deployment. Appendix: Metric Adjustments on the T3 Network by Elise Gerich, Merit/NSFNET Internet Engineering (To fully appreciate the details here it would be appropriate to refer to the map in the file pub/maps/t3topo.ps on merit.edu.) With the advent of the RS960 card rollout, there has been some concern about the performance limits of nodes which have up to three RS960 T3 cards and at least one Hawthorne T3 card. One of the strategies proposed to avoid congestion on the Hawthorne- to-system-to-RS960 interaction is to bypass using links which terminate in this configuration by tuning the link metrics. Since there are multiple paths between any two pairs, it is important to evaluate the effect changing link metrics has on the network as a whole. Since the RS960 card deployment is staged in five phases, we approached the problem by identifying the interfaces where packets would have to traverse both flavors of cards and the system, in each of the four phases of the deployment. The next step was to identify within each phase interfaces which may be underutilized so that we could potentially adjust the metrics to divert traffic from more heavily loaded interfaces to the more lightly loaded interfaces. In phase one, both interfaces are lightly loaded, and it was felt that there was no danger of approaching the performance bottleneck threshold number of packets thru either interface. Therefore, the recommendation is to leave the link metrics unchanged for phase one. In phase two, it is obvious that the majority of the traffic from and to the west coast traverses two interfaces, CNSS8 to 16; and CNSS16 to 64. The objective was to reduce traffic through these two interfaces and to increase traffic through the interface at CNSS96 to 80. In evaluating the multiple paths from the east to the west coast (primarily between Hartford, San Francisco, and Los Angeles it appeared that we could achieve our objective by raising by two the link metrics on two links, 8 to 24 and 16 to 64. In order to test our hypothesis, we raised the link metrics on the links 8-24 and 16-64 from one to three on April 13, 1922 at approximately 16:15 GMT. It was immediately noticeable that traffic was diverted from 8-24 and 16-64 to 80-96. We left these metrics in place for approximately 20 hours. Using the xdview4 program that Bill Norton has written, we graphed the packets per second in and out of the various interfaces on the network. Comparisons of the sample period with the pre and post data samples, indicate that we accomplished our goal of reducing traffic through 8 and 16 and of increasing traffic through 96. In phase three, there will be one purely RS960 path from coast to coast. The objective for this phase was to eliminate multiple, lowest cost paths between Hartford and the west coast nodes of San Francisco, Los Angeles, Seattle, and Denver, and to make the RS960 path (48-32-40-24-8) the lowest cost path (according to link metrics) from coast to coast. After evaluating the multiple paths between Hartford-San Francisco, Hartford-Los Angeles, Hartford-Seattle, and Hartford-Denver, we thought that we could adjust the metrics across the network so that the lowest cost path was the purely RS960 path. This would require changing the metrics on six links. All link metrics on the network would be one, except for 8-24 which is 3, 16-64 which is 3, 96-80 which is 2, 24-80 which is 2, 32-56 which is 2, and 48-72 which is 4. Since this change would force all the east- west traffic onto five nodes, we were hesitant to test the hypothesis on the real network. However, since April 19 was a holiday weekend and the traffic load on the network was very light, we chose to adjust the metrics for a period of five and one half hours. The results of this test were as expected with one exception. I had made a mathematical error when calculating the paths to Denver from Seattle, so the lowest cost path between that pair did not traverse the RS960 path. There was a noticeable reduction of traffic through the following interfaces: 16 to 64, 72 to 48, and 48 to 72. Even 80 to 96 saw less traffic than when the metrics were configured as in phase two. Other observations were, that there appears to be an increase in traffic through interface 32 to 56. That might be attributed to the fact that the lowest link cost between Washington DC and Hartford was then via New York, not Greensboro; however, this may be offset by having two equal cost paths between Hartford and Greensboro. We have not yet completed our evaluation for phase four. The recommendation for phase one is that we leave the link metrics as they are currently; every T3 link is one. The conclusions that we draw for phase two from these experiments are that we can reduce the load on two of the hybrid boxes by diverting traffic to the third, lightly utilized hybrid. We recommend that prior to that phase that the link metrics be increased from one to three on two links: 8-24 and 16-64. As for phase three, significant gains can be made by diverting the majority of traffic to the RS960 path, but we recommend that we investigate further to see if we can eliminate the RS960-Hawthorne-RS960 path between Hartford and Denver. As we conclude our evaluation of phase four, we will publish these results also.
