tools for traffic engineering networks
by Vicky Rode 30 May '04

30 May '04

Hi there, I'm curious to know what tools (in traffic engineering arena) people use in order to manage and verify their service assurance that they are providing and / or receiving they think they are. How do you know the policers are functioning correctly? How do you know whether your service provider and / or your internal traffic is not being over-book? Any recommendations, thoughts, white papers, pointers will be greatly appreciated. regards, /vicky

Re: Open Source BGP Route Optimization?
by Per Gregers Bilse 30 May '04

30 May '04

At first I wasn't sure what a "route optimizer" was supposed to do -- the term is rather generic and could have a lot of different interpretations. A multi-path traffic balancing solution in the style of Cisco's OER has to be tightly integrated with the routing infrastructure. Specifically, it needs first hand BGP peer data in order to work reliably. There will be a number of cases where an add-on solution might be able to improve on certain things, but there is one major hurdle: a BGP speaker only forwards its own best paths, so an add-on analyzer might well never learn about alternative paths. The only way for any implementation to reliably learn (all) alternative paths and otherwise maintain routing integrity is by receiving BGP data first hand, ie directly peer with transit providers and other peers. Best, -- Per

best effort has problems
by Gordon Cook 29 May '04

29 May '04

Greetings Nanogers, I published a two month issue last weekend with the bottom line conclusion that there can be no telecom recovery as long as the industry relies solely on the best effort business model which I believe is not economically sustainable. This has led to two articles on my June-July issue conclusions this week in the trade press. Something that has never happened to me before. :-) The first is ISP Planet and the second Broadband Edge. Here are the urls http://www.isp-planet.com/perspectives/2004/cook_internet.html (monday) http://bbedge.mblast.com/presentation/page798-878156.asp (today) Finally my summary, table of contents and list of contributors is at http://cookreport.com/13.04.shtml Enjoy the weekend. -- ============================================================= The COOK Report on Internet Protocol, 431 Greenway Ave, Ewing, NJ 08618 USA 609 882-2572 (PSTN) 703 738-6031 (Vonage) Subscription info & prices at http://cookreport.com/subscriptions.shtml Report on economic black hole of best effort networks at: http://cookreport.com/13.04.shtml E-mail cook(a)cookreport.com =============================================================

by Andrei Ivanov 28 May '04

28 May '04

Hello I'd like to discuss a strange problem experienced by one of my users in San Francisco. She is connected to Earthlink DSL, and traceroute reveals 63.211.150.25 as first routable IP address. If there is someone here, who [cw]ould discuss connectivity issue between Earthlink DSL customer and Savvis/Exodus hosted network, please contact me via e-mail. Thanks. -- andrei

Re: Looking for comp-priv listserv archive from early-mid 1990s

A bit of hunting finally turned up mlist.com-priv: http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&group=mlist.com-priv but that's only a partial archive (not sure how far back it goes and I didn't see an easy way to jump to the first message). The thread http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&threadm=6n9a8n%24os5%40b… or, if you prefer a concise URL: http://tinyurl.com/2xw3e has a pointer to http://www.mit.edu:8008/MENELAUS.MIT.EDU/com-priv/ which looks like a complete archive: http://www.mit.edu:8008/MENELAUS.MIT.EDU/com-priv/1 is dated 5 Oct 1990. The interface for the archive is not pretty.

SNMP security survey
by Wes Hardaker 27 May '04

27 May '04

On Tuesday at the meeting I polled the audience for information about whether or not SNMPv3 was easy to use and deploy from a security perspective, and what user databases were in use by operators aside from what SNMPv3 uses (talk details and slides: http://www.nanog.org/mtg-0405/hardaker.html ). Thanks to those of you that took part in the hand-raising exercise! At the end of my talk, I also posted a web site for an online survey for people to fill out a short questionnaire as well, but after my talk ended the network was taken down so I thought I'd post the web site here once more in case people weren't able to fill it out that day: http://www.Net-SNMP.org/cgi-bin/survey Note that even if you don't use or don't like SNMP at all, please consider filling it out anyway as it asks some other important questions like what type of user account databases you use that would be helpful to us even if you don't now or intend to ever use SNMP. Thanks! -- "In the bathtub of history the truth is harder to hold than the soap, and much more difficult to find." -- Terry Pratchett
