Kobe Steak
by Scott Call 18 Feb '01

18 Feb '01

we're gathering in the 1st floor lobby-like area (where the nanog reg desk is) to go to Kobe Steak. Anyone is, of course, welcome. It's about 15 minutes from the hotel by car. I can carry 3-4 additional people (3 engineer sized, 4 if we're lucky) in my rental, so anyone else who has wheels s encoraged to join. If you want to follow later or ask us to wait a few, call me +1 925 212 2200 and we'll make arrangements. -S Scott Call Router Geek, ATGi "Only the Phoenix rises and does not descend And everything changes.

Looking for a RIM 857/957 Cradle at Nanog Meeting (Mission Critic al..?.)
by Dan Ellis 18 Feb '01

18 Feb '01

Welcome to Atlanta, Sorry for the off-topic message, but it's semi-citical(if you rely on your RIM, you know what I mean). Any assistance is greatly appreciated. It seems that my RIM 857 has lost its mind and needs a software download. I have the application and software, but need to borrow a cradle for 10 minutes. If anyone has a 857 or 957 cradle I can borrow for a few minutes, please mail me(ellis(a)corp.ptd.net) and we will arrange a place to meet in the Sheraton. Thanks in Advance --Dan -- Daniel Ellis, Director of Engineering - PenTeleData LP1 (610)826-9293 www.PenTeleData.net "The only way to predict the future is to invent it." --Alan Kay

The Cidr Report
by Tony Bates 18 Feb '01

18 Feb '01

This is an auto-generated mail on Fri Feb 16 23:00:00 PST 2001 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

None of this funky CDROM or download the page from the Cisco web site when your cisco router isn't routing and you can't get to the cisco web site. And my favorite. You didn't have to pass a test to buy stuff directly from Cisco. I got my first IGS-R for 50% off because Cisco was competing against Proteon, and the Cisco sales person was happy to sell me one.

Re: T3 Latency
by Walter Prue 17 Feb '01

17 Feb '01

Chuck, The question posed by Chris, "how long is your access line"?, is a rather important data point before answering your question. I have a T3 that is about 15 miles long. It runs between two 7500 routers. Its minimum ping round trip time with 100 byte pings is 2 ms. It is not very heavily loaded with peaks of about 10 Mb/s today and the max round trip time was 21 ms. So that should give you some minimal bounds of what you might expect. As the saying goes your mileage may vary. Speed of light does play in here, if the circuit is longer. Also intervening electronics such as a frame cloud or telco muxes also add latency. Walt
