I hope that you continue to refine your analysis of not only the 9 "popular" Root Name Servers but all of the Root Name Servers. The discussion on the "newdom" list, at one time was focused on the simple objective of configuring more Root Name Servers around the world. Maybe this can be a kick-start to help get everyone refocused on that objective. Thanks for the fine work. I am working on a web site to help people learn more about name servers. It is temporarily at the following address, <http://www.unety.net/Platform>. If you do not mind, I will be happy to incorporate some of your points. If you ever develop a web site, showcasing your analysis talents, let me know. I can add a link and I think that everyone would benefit from the work that you have done.

IS-IS questions
by Bradley Dunn 24 Nov '96

24 Nov '96

Hi. I asked on comp.dcom.sys.cisco a few days ago about the advantages of IS-IS over OSPF. Dave Katz replied that IS-IS has proven to be very extensible while still allowing for backward compatibility. IS-IS was also overhauled around the same time that a lot of ISPs were building their networks. My questions are these. When is a good time to use IS-IS? Should an ISP that wants to build a scalable network go with IS-IS right now? Or is there a certain point where IS-IS becomes desirable over OSPF? Is there ever such a point? I would think it is better to pick an IGP and stick with it. Thanks for any comments. -BD

You don't understand the recursion flag, do you? Tell me, Jim, what would happen if you were right: What would happen if the root servers did not have an 'options no-recursion' option in the bootfile? (or, as your limited knowledge thinks, "named -r"?) Think, Jim. Think really hard. *.root-servers-net are "primary" nameservers for SLD's in the .COM zone. If you queried a root-servers.net nameserver for "mcs.com any" and got back a list of nameservers, you'd theoretically NEVER be able to get MCS.COM records. Here is how you test recursion: dig @a.root-servers.net some-hostname.xyz.com where 'some-hostname.xyz.com' is NOT a listed host for any domains. Here's proof.

The Cidr Report
by Tony Bates 23 Nov '96

23 Nov '96

This is an auto-generated mail on Fri Nov 22 12:00:00 PST 1996 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.

Dima, Good observation. However, I did not miss Vadim's point. It is well stated. But I would like to see a clearer path to deterministic behaviour in routing technology before we use it for integrated voice service, as an example. "No worse than ATM" is not a good enough starting point. Indeed, today we use ATM to transport IP traffic and also multiple technologies including some non-ATM stuff like broadcast video/voice, laser disk playback, Video Conferencing, and ordinary T1 AMI/D4 PSTN voice service. I wonder, however, if an IP address (even at terabit speeds) will help to sort out which DS0 is going to which IXC. Likewise, we should never think that IP traffic will ever be limited to any specific L1/L2 technology. Because I can do these things with ATM today does not mean that better IP routing engines are not needed! I mean no disrespect to Vadim. I think is work is good. I actually hope we do see better IP routing technology. If the resultant product is deterministic at L3, ATMnet would probably be one of the first to sign up to give it a try. ..mike..

Indeed, I do not dispute many of your points regards route-flap and role of IX. However, IMHO you have constructed a non-existent foe solely for the purposes of argument. Specifically your statement: "The following ... argue that native IP routing is the only currently existing technology which can hold a global data network together." This is a point that no one with a clue is disputing WRT Internet IP traffic. Even though ATMnet has been delivering IP-over-ATM to commercial users longer than any other provider, we never claim that the Internet should exist *EXCLUSVELY* as ATM technology. Quite the contrary, we (and our customers) see the technical and economic power of ATM technology in the ability to support fully integrated services. On the other hand, no one with a clue can dispute that we need to push for better IP routing technologies, regardless of the L1/L2 medium used. ..mike..
