The Cidr Report
by Tony Bates 11 Aug '00

11 Aug '00

This is an auto-generated mail on Fri Aug 11 12:00:00 PDT 2000 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

RIPE-181 server to be decommissioned
by gerald＠merit.edu 11 Aug '00

11 Aug '00

As many of you know, Merit began a production RPSL service on 11/1/99. RIPE-181 and RPSL coexisted on our production server until 1/1/00; after that date, RIPE-181 updates were no longer accepted and only queries were available on the special RIPE-181 server. Merit will now complete the final stage of its transition to RPSL by decommissioning its RADB RIPE-181 server on Wednesday, August 23, between 5:00-8:00 A.M. EDT. Query activity has been extremely light on the RIPE-181 server and the remaining users have been notified by private email about the termination of this service. This change will not impact our production RPSL service. Please send your questions and comments to db-admin(a)radb.net. IRRd Team --Gerald Winters

Vorerhebung Bandbreitenerhoehung VIX - Router
by Vyskocil Martin 09 Aug '00

09 Aug '00

Hallo Gerhard! Gestern fand eine Besprechnung mit der Uni-Wien; VIX statt. Die notwendige Hardware wird von Hrn Saumwald (TA) koordiniert. Die Anbindung des Highway zum VIX wird von ATM auf "dark Fiber" umgeschalten werden. Am VIX beginnen diesen Freitag die vorarbeiten zu Freischaltung der entsprechenden Leitungen. Die Schaltung der Leitung wird von Hrn Weissensteiner (TA) koordiniert. Dadurch wird es notwendig ein 2tes 100MB Interface zum VIX-LAN zu aktivieren. Zur Realisierung wird vom VIX die Fast Ethernet Option des Catalyst angeboten. Konfiguration (bestehend): - Anbindung Highway: ATM 65 MB - Anbindung VIX-LAN: 100 MB Konfiguration (neu): - Anbindung Highway: "dark Fiber" 155 MB - Anbindung VIX-LAN: 2 * 100 MB Konfiguration (neu) Stufe 2 (langfristig) - Anbindung Highway: "dark Fiber" 2 * 155 MB fï¿½r Backup- loadsharing- - Anbindung VIX-LAN: 2 * 100 MB Wie besprochen bitte um Klï¿½rung, ob unsere VIX Routerkonfiguration die Fast Ethernet Funktion unterstï¿½tzt, sowie um Aktivierung (in Abstimmung mit VIX und Betrieb). lg Martin ---------------------------- Martin VYSKOCIL Telekom Austria AG Product- and Service Development Tel.: +43 1 79711 1625 FAX: +43 1 79711 1608 mailto:mvyskocil@highway.telekom.at

Thanks for this - I hadn't even noticed these changes but then haven't studied the data in depth for a while now. I had noticed what appeared to be an acceleration in the number of ASes being distributed by the registries, and I think these numbers confirm it. >Whilst these are not precisely-calculated ratios at all, and there may be >many reasons for this change, I would be interested in hearing what is >behind this shift. Anecdotally, I think we are beginning to see a large >increase in the number of enterprises (rather than ISPs) who are running >BGP. I think you are right. More and more non-SPs are multihoming now. It is certainly educational to look through the recent assignments made by ARIN (given that is the region which is "burning" ASes the fastest) - very few SPs in there (going by the names anyhow). >1.

I'll be interested to see what happens when >the global table reaches 100,000... Should it be a problem? I'm told that several providers are already running well over 100k prefixes in their iBGP. The knock-on effects I'm expecting are more to do with stability of the routing table. So far, there is no evidence to suggest there is any instability, even with this growth. >2. Increase in the number of ASes in the Internet Routing Table. What are >the statistics looking like here? Do we have an acceleration in growth >here as well? If so, is there a risk of running out of ASNs in the BGP >IPv4 routing-table? It is accelerating, but note that 8000 ASes are present in the routing table out of approximately 16000 which have been assigned... I wonder where the others are, apart from in back pockets? ;-) Looking at the previous 12 months, we're seeing about 680 new ASes per quarter. It is accelerating slowly, and there are over 47000 left, so would last around 12 years at a sustained assignment rate of 1000 per quarter. Should we worry - well, probably not with the current usage pattern, but if multihoming is going to move from the large/medium enterprise to the SOHO, or even residential, a unique AS per site may become a non-scalable solution. >What do others see as possible explanations for the phenomenon? The other thing to bear in mind is that the "developing regions" still have to catch up with North America and in some case, Europe, when it comes to resource consumption. I'm thinking of China, India, other parts of Asia, Latin America and Africa - big growth potential here in the near future. So far I've counted a total of 94 ASes assigned to African Internet sites, and 488 ASes assigned to Latin American sites. This compares with 10000 for the US and Canada alone! cheers, philip -- -------------------------------------------------------- Philip Smith ph: +61 7 3238 8200 Consulting Engineering, Office of the CTO, Cisco Systems --------------------------------------------------------

Hi folks, I don't know if any of you have been paying much attention to the total size of the routing table, but its growth rate has started to accelerate since the start of the year. Since the 28th January we have added around 13500 prefixes (8000 of those were /24s). This time last year the table had 62500 prefixes in it. 6 months later it had increased to 71000, and now it is at 84500. 5000 extra prefixes above linear growth. - With a linear growth rate, the routing table will hit 100k prefixes around early March 2001. - Assuming the accelerated growth rate we are seeing now, the routing table will reach 100K around about the end of December this year. (I remember predicting at the Adelaide IETF that we'd hit 100k around September 2001 - based on the time period Mar99 to Mar00.) An interesting landmark to look forward to...! philip -- >Delivered-To: lists-routing-wg-out(a)lists.ripe.net >From: Routing Analysis <cscora(a)dev.apnic.net> >Subject: RIPE NCC Region Weekly Routing Report >Date: Fri, 28 Jul 2000 04:02:20 +1000 (EST) >Reply-To: pfs(a)cisco.com >To: routing-wg(a)ripe.net >X-Mailer: fastmail [version 2.5 PL1] >Sender: owner-routing-wg(a)ripe.net >X-SMTP-HELO: postman.ripe.net >X-SMTP-MAIL-FROM: owner-routing-wg(a)ripe.net >X-SMAP-Received-From: outside >X-SMTP-PEER-INFO: postman.ripe.net [193.0.0.199] > >This is an automated weekly mailing sent to the RIPE Routing WG e-mail list >describing the state of the Internet Routing Table in Europe, Middle East >and North Africa.
