by B. Regan Knapp 10 May '95

10 May '95

Hi Everyone, I've just made some information available about the upcoming NANOG meeting on Merit's WWW site. I've included the draft agenda, information about hotels, maps and directions, and a registration form you can fill out online. You can find this information by going to the Merit Web home page (http://www.merit.edu) and choosing "NANOG May 22-23" under the "Upcoming Conferences" heading. I'll be making more information available on the Web as I get it, so keep checking back! For those without Web access, the registration form and attached information will be e-mailed to this list one more time before the meeting. Regan Knapp Webmaster for Merit's National Networking Activities -- Regan Knapp Vox: (313) 936-0320 Merit Network, Inc. Fax: (313) 747-3185 4251 Plymouth Rd.

Pointer to ATM performance work?
by Richard Colella 09 May '95

09 May '95

I seem to remember discussion at one of the meetings of some ATM performance work that looked at the benefits of discarding whole TCP packets when a cell was dropped. Can someone give me a pointer to this? --Richard

The Internet needs *much* better tools than what the NSF RA project offers today (eg the relabeled work done by Ripe) and what they have made public about future plans. (Next days delivery in a millisecond world is not very usefull.) Either the Internet at large develops real tools for a "offline registry" or we have to move this into the exterior routing protocols. -Peter

Sprint has nothing to do with the loops. Gordon -- you as a practioning journalist should know better than to trust "information" of hear-say, particluarly when the source explicitly disclaimed any first-hand knowledge. Sprint customers are informed about scheduled maintenance and outages by means of a special mailing list. --vadim Did this happen on Friday? If so I heard from a directly knowledgeable source that there was a power failure in Dallas that affected the MFS pop there and that MFS had to bring in a truck with generators to get the node operational again. If this is correct wold the looping be really blamable to either UUNET or Sprint? ******************************************************************** Gordon Cook, Editor & Publisher Subscript.: Individ-ascii $85 The COOK Report on Internet -> NREN Non Profit. $150 431 Greenway Ave, Ewing, NJ 08618 Small Corp & Gov't $200 (609) 882-2572 Corporate $350 Internet: cook(a)cookreport.com Corporate.

MAE-east weirdness
by David Levine 08 May '95

Hey folks. I'm working with my friends at National Public Radio. They're having network problems, and I'm not sure the correct people at UUNet to report this anomaly to. The answer NPR got from UUNet was: MFS trouble in Dallas. Does that make sense? any suggestions? thanks in advance. sorry for the interruption. # /usr/local/bin/traceroute npr.org traceroute to npr.org (199.0.132.69), 30 hops max, 40 byte packets 1 router.butterfly.net (199.73.40.1) 7 ms 5 ms 3 ms 2 s0.router.clark.net (199.73.41.254) 12 ms 15 ms 12 ms 3 sl-dc-1-S19-T1.sprintlink.net (144.228.4.1) 19 ms 29 ms 17 ms 4 sl-dc-8-F0/0.sprintlink.net (144.228.20.8) 21 ms 19 ms 17 ms 5 sl-mae-e-H2/0-T3.sprintlink.net (144.228.10.42) 26 ms 18 ms 19 ms 6 Vienna1.VA.Alter.Net (192.41.177.249) 26 ms 297 ms * 7 sl-mae-e-F0/0.sprintlink.net (192.41.177.241) 22 ms 31 ms 44 ms 8 Vienna1.VA.Alter.Net (192.41.177.249) 62 ms 87 ms * 9 sl-mae-e-F0/0.sprintlink.net (192.41.177.241) 37 ms 36 ms 28 ms 10 Vienna1.VA.Alter.Net (192.41.177.249) 63 ms 83 ms 77 ms 11 sl-mae-e-F0/0.sprintlink.net (192.41.177.241) 21 ms 32 ms 27 ms 12 Vienna1.VA.Alter.Net (192.41.177.249) 40 ms 50 ms 68 ms 13 sl-mae-e-F0/0.sprintlink.net (192.41.177.241) 33 ms 19 ms 31 --Dave http://iron.butterfly.net/motodave

Gordon, Karl this might be instructive. NPR is currently connected to AlterNet, not Sprint, btw. --Dave ---------- Forwarded message ---------- Date: Mon, 8 May 1995 13:19:46 -0700 From: Jon Postel <postel(a)ISI.EDU> To: motodave(a)butterfly.net Cc: postel(a)ISI.EDU Subject: Re: MAE-east weirdness Dave: Hi.
