Anyone know of an online resource for checking facilities/providers by building address? Is it on-net, is it Sonet, that type of thing. Thanks, Andrew -- Andrew J. Doane Dotspot, Inc. v:630.799.7500 x33913, f:240.337.2349 e:andrew.doane@dotspot.com p:1161673@skytel.com

Network Sizing Guidelines?
by Daniel R Glover 05 Mar '01

05 Mar '01

Can you point me to some current network sizing advice for Internet service (WAN and LAN)? I am looking for rules-of-thumb, guidelines, equations, books, or even anecdotal evidence that would help me in evaluating future network design concepts. I have somewhat unconventional network constraints, but I would like to start from current conventional assumptions on, say, numbers of users (home or office) that can be supported by various bandwidths. I've tried the related links off the NANOG pages, but some are old or broken. I have found some advice like "a T1 will support 200 to 300 28K modem users," but I hope there may be more current advice somewhere especially with regard to QoS, future trends, and to larger networks. Any relevant pointers or advice would be welcome. R/ Dan Glover

@HOME AS6172 Problems

Anyone from the @HOME NOC out there?

The Cidr Report
by Tony Bates 03 Mar '01

03 Mar '01

This is an auto-generated mail on Fri Mar 2 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

What's worse is when Taligent's going under makes XO turn down your T1 so your primary nameserver (which is stupidly located on the same T1 as the webserver) goes down and it takes AGES to get the nameservice restored because NSI/Verisign are too slow to fix it... well, let's just say that mails to my domain are bouncing right now, due to the zone expiring and the secondaries not being able to reach the primary.
