Informal public hotspot BoF/lunch at 12:15 Monday in the RegencyFoyer (we'll try to move to a local eatery after we gather)
by Dan Ellis 15 Oct '04

15 Oct '04

Hi all. I am Dan Ellis, CTO of PenTeleData. We are a regional ISP/communications company owned by 7 cable and telephone companies, responsible for 150k+ broadband subscribers and associated IP infrastructures. Like many MSO's, we are looking at rolling out a large (300-500+ AP) distributed public hotspot infrastructure and have seen the following issues with both commercial and open source solutions: - Lack of subscriber accountability (NAT translations). - Inability to see per subscriber "ip accounting/netflow" statistics. - Lack of strong MAC and IP security (easily hijackable) - Inability to control subscriber speeds. - Poor OS implementations (no ssh, non robust upgrades) - Limited or no radius accounting records. - Limited subscriber time/max-transfer control. - Inability to perform internal or external IDS (quarantining). - Limited best practices guides dealing with the above items. - Numerous issues with operator deployment methods. At the BoF, we hope to compile a list of requirements for vendors in order to get a better set of gear we can build a manageable hotspot infrastructure from. We'll present our requirements along with any other sets people have, then throw the floor open for discussion. I will attempt to steer vendors towards these requirements, work on a best practices guide, and then present my results to the Nanog community. Tim Pozar, Avi Freedman and I will gather for this informal BoF in the Regency Foyer at 12:15pm on Monday, 10/18/04. If the crowd is of an appropriate size, we'll then move to a local eatery. Hope to see you there, --Dan -- Daniel Ellis, CTO, PenTeleData (610)826-9293

Seeking Technical Input from Metro Ethernet Providers and MAN-like Enterprise Users
by Robert Hayden 15 Oct '04

15 Oct '04

Good day, As many of you know, I am a network engineer at the University of Wisconsin, Madison. We are currently in the preliminary planning stages of our next generation campus network and would like to get some ideas on what the "real world" is actively doing to focus in on the appropriate technologies and equipment. Our campus consists of approximately 200 buildings over a few square miles as will as a fairly traditional hub-and-spoke fiber plant. Currently, we use Cisco ethernet equipment (primarily 6500s/Sup720 for core aggregation and routing, and 3750s for edge connectivity) and 802.1Q VLANS to provide per-department layer-2 connectivity. Each department gets their own VLAN(s) with some departments spanning throughout the campus to many buildings and some networks as small as a handful of ports. When our current buildout is completed we'll have about 4500 network elements and about 140,000 edge ports. What we have been seeing with our current implementation is problems of scalability. 802.1Q simply seems to fall down when implemented wide-scale in a MAN/WAN environment (especially when using a redundant connectivity model). We want to look into newer MAN technologies (likely some variation on the MPLS theme). What I am looking for are some engineering contacts at some ethernet metro-type providers as well as large enterprise and academic campus that have moved beyond 802.1Q for L2 VPNs. My hope is that you might be willing to be available for a brief conference call and/or to provide other insight as to how you handle very-large and scalable ethernet networks with a variety of service requirements. We've gotten a variety of information from our vendors, but we tend to take a lot of that as marketing and would much-prefer to discuss this with "real" people. If you'd be willing to be of assistance, please drop me an email and I'll follow up privately. Thanks much for your time.

VoIP peering technology review: request for information
by John Todd 15 Oct '04

15 Oct '04

I'd like to review any methods by which operators are currently exchanging e.164 telephony route information between VoIP systems (excluding SS7.) In the last ~1 year, I have not heard of any significant changes in the manner in which routes are exchanged; the typical method still seems to be Excel spreadsheets or CSV files. ENUM seems to be gaining some ground, with providers populating their own root servers, but I haven't heard of or seen a complete specification from anyone - it's been mostly rumor, so detailed implementation examples of ENUM use would be appreciated. Bonus points for telling me how this scales without a single root to bind them. If you are using an automated method to inform your VoIP telephony "peers" of new VoIP-enabled DIDs or (more importantly) routes that you offer, I would like to hear about it, even if it's just a sentence or a link to go find more information. Do you use TRIP? XML exchanges? SQL over TCP? LDAP? I am especially interested in "accessible" methods that don't require significant capital investment in proprietary technology, hardware, or service provider products. Just as important would be the topics of non-disclosure between peering entities and other political issues surrounding exchange of customer (specific) or route (general) data and the threat of unveiling your customer base details to your competitors. That discussion makes me think of the same arguments 10 years ago with BGP... I am often asked to speak and write on the topic of VoIP peering (if there is such a thing) and I am trying to prevent being out-of-date on this quickly changing environment. I am not able to keep up with digging through the marketing foam to find the good information underneath, so I'm probably missing some interesting trends. All answers will be anonymized unless you specifically request the answers to be publicly attributed. Please reply privately; a summary of useful data will be sent back to the list(s). JT

NANOG 32 PGP key signing announcement
by John Kristoff 15 Oct '04

15 Oct '04

For those that have added your PGP key to the keyring at biglumber, thank you. If you have not yet submitted your key, please do so, and know that you can safely ignore the remainder of this message. At NANOG 32 we will be trying out a new, hopefully greatly improved method for signing keys for those who have submitted their key in advance. It is our hope that this will greatly expedite the signing process in order to minimize time away from any beer BoF. To partake in this new process, you must do the following: 1. Download the early submission NANOG 32 key list from here: <http://aharp.ittns.northwestern.edu/tmp/nanog32-earlykeys> 2. Verify the MD5 and SHA-1 message digest for the above file. Your calculation of those values should be as follows: MD5: b008f14388cb2abbf1c695808a40b1eb SHA-1: 22737af62b1278590074bdabebb0b3d9f57d53b0 3. Bring a hard copy of the key list and your calculated message digest values with you to the keysigning event on Monday night. The file above is a snapshot from the keyring on biglumber at UTC 14:00, Friday, October 15. There were a total of 27 keys on the keyring at that time. After a brief PGP introduction Monday night, I'll read aloud the message digest values for the file in the link above (they should match the values in this message shown above). Each participant in the early key list simply has to confirm or deny that the fingerprint from the file is indeed their's. For those in this group, there is no need to read aloud your entire fingerprint. Of course, you still need to go around and verify identities as we've always done. This is done according to your own policy, but it is recommended that you have at least two trustworthy forms of picture identification (e.g. driver's license and passport). Additionally I will bring the hard copies of the key list, as of 6:00 p.m., local event time, to the keysigning event. This will include all keys, including those submitted after UTC 14:00, Friday, October 15. Signing keys between early and later submission groups will occur in the traditional fashion. If you have any trouble obtaining the key list, verifying the message digest values above or even have general questions about the process feel free to shoot me an email off list.

Some inband to the protocol conversation at hand and some not. Should one fail negotiation can still happen. In most cases traffic should still flow. I think the DF bit is a mistake and should not be used, except when probing with multiple packets on the wire. I think giving vendors a free pass on bad fragmentation performance is also a problem. Nothing that couldnt have been solved with the ooddles of cheaply available memory we have now. And by that I mean the vendors who consistently shipped routers that had only performance resources for bare bones routing. (OT Rant: The price margin of the routers being high enough that doubling the shipped memory load and enabling upgrades to limits comparably available to popular cheap computing equipment out there should not have broke the bank on these routers. There really was no excuse for 10K equipment coming in with a tenth of available computing resources that can be had at 1K. It boggles the mind the free pass they got on that. Saying performance is only required of the ASICS that switch was incredibly short sighted -- and selfish) (OT Rant #2: The whole firewall is not a router -- merely a copout because all these routers turn out to be wimps doing anything not limited to switching packets from one interface to another. The best place to handle policies and security detection for packets is where they are already being handled -- the router. ANd the reward for the copout? Big bucks for commodity computers with mediocre software.)(OT #3: How about a firewall protocol to exchange return traffic information between a set of firewalls so that assymetricity works again and firewalling can be done at the SP level. Does such a thing exist and if so who supports it) How about some more tcp or ip options so that machines can tell each other what packet sizes are actually coming in, fragmented or not? No dropping of packets. The larger they are when they come in the better. Any protocol that detects duplicate data can probe with multiple packets on the wire. Must be better for slow start, exponential back-off model. -- Inband How about a UDP port designated for IP packets with these options and magic cookie values to prevent spoofing? -- Completely outband Easy enough so that firewall vendors will have that on by default. How about an additional ICMP type dedicated precisely for this? "Packet was sent fragmented, to avoid this lower sending packet size to X". Kind of the opposite of Frag needed but DF set message.If this fails to work, well we have more fragments. Much better than having stalled traffic. -- a little different than current algorithm of drop first notify later It seem everyone keeps trying to figure out how to fix the implementation of PMTUD or to work around it. Perhaps a new solution will gain enough traction that the current mechanism will become obsolete. Problem solved. Add in some algorithm fixes as mentioned for the broken PMTUD of today and conversing hosts should have more tools than they can use to discover and take maximum advantage of pmtu, OR in the alternative, still exchange network traffic. Much better than a single mechanism for detecting PMTU which if fails can cause a blackhole of your packets. If we ever want to aggressively lift MTU's in tomorrows network we really need to solve this with enough nails and screws that it aint coming back out again. And I dont want to hear that ipv6 fixed this or that -- except if its possible to apply the lesson learned to the protocol most of us actually use. (not that I actually know if/how it works better in ipv6) because we all know that ipv4 is here to stay in its dominant position for at least 5-10 more years. It will need to be supported for possibley another 20. Joe >Steve > > > > >

3 Mb question
by Gerald 14 Oct '04

14 Oct '04

I've got what seems to me like an innocuous question for this list... Someone is requesting access to about 3 mb of traffic up/dn. I figure 2 T1s will give them the 3 Mb I need, but I'm looking for suggestions on either efficiently combining those 2 to get the most bandwidth for their buck or else I have to look at getting them a ds3 and scaling back to what they need. Is there an good low end suggestion for making effective use of 2 T1s to give 3 Mb of bandwidth? In practice, I've seen 2 T1s load balanced with CEF not do very well at giving a full 3 Mb. (This was without turning on per-packet CEF) I'm not personally experienced with MLPPP or mux hardware if that helps, but I could get it set up if that's the consensus as the best option. The NRC of something that would effectively couple the 2 T1s would easily beat the MRC of a DS3 which I think might be overkill for just 3 Mb. Thanks for suggestions and tips. Gerald
