Someone needs to flog the marketing people at Sprint .. http://www.sprintbiz.com/ip/backbone.html "Sprint's Internet backbone includes redundant equipment and diverse routing to ensure the highest reliability. Leveraging Sprint's advanced SONET network, we have specially engineered our network to take full advantage of SONET reliabiliity. In addition, Sprint uses the Cisco Gigabit Switch routers in its backbone, which translates into greater response time and reliability for your users" oops. ========================================================================== Eric Germann CCTec ekgermann(a)cctec.com Van Wert, OH 45891 http://www.cctec.com Ph: 419 968 2640 ICQ: 41927048 Fax: 419 968 2641 Network Design, Connectivity & System Integration Services A Microsoft Solution Provider

Why is the contractor waiting around? I'm not very familiar with how things are done in the construction industry, but I see a lot of paint on roads and sidewalks around here. I've seen occasional people out putting down paint without any contractors waiting around. I thought the standard practice was to mark the limits of the area you want to dig in with "USA" (Underground Service Alert) and then call the USA 800 number a few days before you want to dig there. That gives the USA people time to contact all the utilities so they can come out and mark the area. I should read the fine print on a call-before-you-dig sign the next time I get a chance. > As far as sending a big bill to the contractor.

BGP problems

Has anyone noticed any BGP problems in the past day? Specifically, problems with Sprint filter routes that they weren't filtering before. -- James Smith, CCNA Network/Systems Administrator DXSTORM.COM http://www.dxstorm.com/ DXSTORM Inc. 2140 Winston Park Drive, Suite 203 Oakville, ON, CA L6H 5V5 Tel: 905-829-3389 Fax: 905-829-5692 1-877-DXSTORM (1-877-397-8676)

IP-Internets
by Bulent Yener 15 Oct '99

15 Oct '99

Coming from an academic research background, I need a reality check. I would appreciate your answers/thoughts etc. to the questions I have below on WANs. 1- are there any all-IP backbones? what is the layer 2 in IP backbones (PPP, ATM, Frame relay...)? 2- how commonly is IP over ATM used? Do network operators really care about the cell-tax? 3- what is the approximate number of connections to a router (i.e., fan-in, fan-out of a router (i) at the edge, (ii) at the core, and (iii) at the backbone? 4- what is the maximum distance between any two points in a autonm. system? 5- what is the approximate ratio of copper/fiber at the edge, core, backbone links? 6- how tight is the physical space in the router rooms (i.e., is it almost a must to take out an old box in order to add one)? 7- in case of a node/link failure what is the average/approx period of time for (i) detection and (ii) recovery I thank you in advance Bulent _____________________________________________________ Bulent Yener Information Sciences Research Center Bell Laboratories, Lucent Technologies 600 Mountain Avenue, Room 2T-314 Murray Hill, NJ 07974 email: yener(a)research.bell-labs.com phone: (908) 582 7087 fax: (908) 582 1239 _____________________________________________________

The Cidr Report
by Tony Bates 15 Oct '99

15 Oct '99

This is an auto-generated mail on Fri Oct 15 12:00:00 PDT 1999 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.

october 16th is the first anniversary of the death of jon postel. while it might be tempting to shut the net off for an hour in memoriam, it does not seem very responsible. i intend to shut down my personal home/office site and all servers there for the day. others may have their own ways of expressing respect and regret. randy

Advantis/IBM/AT&T Contact Needed
by Derek J. Balling 15 Oct '99

Does anyone have a valid contact for a person possessing clue within Advantis (which I guess was recently sold to AT&T)? I need to talk to someone about what appears to be a horribly misconfigured caching proxy. D
