anycast stability experiment
by Randy Bush 24 Feb '05

24 Feb '05

the verisign gang gave a good presentation of "Life and Times of J-Root" at the recent nanog meeting' see <http://www.nanog.org/mtg-0410/pdf/kosters.pdf>. on foils 27 to 29, they reported non-trivial routing jitter and therefore suggested "DO NOT RUN anycast with stateful transport." on the other hand, for almost a decade, there have been reports of successfully delivery of stateful services over anycast. so one wonders if their measurement was from an abnormal vantage point, or if there are other interesting things going on. as we are curious and inclined to test conjectures by experiment, scientific method and all that, we devised a small experiment in which we would very much appreciate your participation. we wish to collect data on the stability of which actual anycast root server(s) you contact from many points on or near the net's edges, i.e.. your home, datacenter, .... to do this, peter boothe, of university of oregon, has written a script which queries those roots which are known to be widely anycast every few seconds using dig [options] @<foo>.root-servers.net. hostname.bind chaos txt to record which actual unicast-named server was reached. these probes are recorded in a file that looks like, for example 42.666.7.11 Sat Nov 13 01:29:29 UTC 2004 f UDP pao1e.f.root-servers.org Sat Nov 13 01:29:29 UTC 2004 i UDP s1.lnx Sat Nov 13 01:29:30 UTC 2004 j UDP jns4-kgtld.j.root-servers.net Sat Nov 13 01:29:30 UTC 2004 k UDP k1.linx Sat Nov 13 01:29:30 UTC 2004 m UDP M-d3 Sat Nov 13 01:29:30 UTC 2004 c TCP lax1a.c.root-servers.org Sat Nov 13 01:29:31 UTC 2004 f TCP pao1c.f.root-servers.org Sat Nov 13 01:29:31 UTC 2004 i TCP s1.lnx Sat Nov 13 01:29:31 UTC 2004 j TCP jns1-kgtld.j.root-servers.net Sat Nov 13 01:29:32 UTC 2004 k TCP k1.linx Sat Nov 13 01:29:33 UTC 2004 m TCP M-d3 Sat Nov 13 01:29:35 UTC 2004 c UDP lax1a.c.root-servers.org Sat Nov 13 01:29:35 UTC 2004 f UDP pao1e.f.root-servers.org Sat Nov 13 01:29:35 UTC 2004 i UDP s1.lnx Sat Nov 13 01:29:35 UTC 2004 j UDP jns3-kgtld.j.root-servers.net Sat Nov 13 01:29:36 UTC 2004 k UDP k1.linx Sat Nov 13 01:29:36 UTC 2004 m UDP M-d3 which is mailed off to peter's collector once a day. note that your public ip address is the first thing in the file. this is learned by wget (or telnet to port 80, in case you do not have wget installed) to peter's server at oregon, which responds with the public ip address from which you came. this serves two purposes: o we may want to know from where measurements were taken so we can look at routing data to see why anomalies or normalities occurred. o we are concerned about overloading the root servers against which this experiment is running. therefore, the script will not actually perform the probes unless peter's server responds to the ip address query. this allows peter to throttle or disable the experiment should 10,000 people decide to run it. it might also be used to select probers to concentrate on 'interesting' probe locales in the internet topology. it's just a short shell script, so you should be able to easily feel comfortable that it will not make you vulnerable to anthing other than possible expulsion from the nanog mailing list :-). as it probes only a select list of anycast root servers, and does so every two seconds, this should not place any significant load on the servers or your machine. as our conjecture involves verisign's implication of stateful, e.g., tcp, connections, early reviewers of the experimental setup pushed us to test tcp as well as udp queries. as a tcp query is estimated to have many more packets than a udp query, the current code does one tcp probe every ten udp queries, i.e., around once every 20 seconds. we would really appreciate it if you would run this for a day or three. a tarball with the script and a readme can be found at <http://rip.psg.com/~randy/anycast_gatherer-1.4.tar.gz> [ fyi, my personal bet is that it's usually pretty stable except for sites in strangely unstable routing environments. but i am under my quota of wrong for the week. ] thanks! and many thanks to the early reviewers of the experiment. randy, peter, and friends

[apologies for duplicate e-mails] New RIPE Document Announcement -------------------------------------- A revised document is available from the RIPE document store. Ref: ripe-343 Title: IPv6 Address Space Management Author: Paul Wilson, Raymond Plzak, Axel Pawlik Date: 22 February 2005 Format: PS=53986 TXT=13567 Obsoletes: ripe-261 Short content description ------------------------- This document provides the management process for IPv6 global unicast address space whereby address allocations are made from a single global pool according to a "sparse allocation" algorithm. In this version, previously published as ripe-261, we fixed an error in the 6-bit address space table. Accessing the RIPE document store --------------------------------- You can access the RIPE documents in HTML format via our website at the following URL:. http://www.ripe.net/docs/ipv6-sparse.html The RIPE Document Store is also available via anonymous FTP to ftp.ripe.net, in the directory ripe/docs.

Announcement Routing Registry Training Courses
by RIPE NCC Training 21 Feb '05

21 Feb '05

------- Dear Colleagues, [apologies for duplicate postings] As a service to its members the RIPE NCC offers the "Routing Registry Training Course". The main objective of the "Routing Registry Training Course" is to familiarise the LIRs with the features of the Routing Registry, while introducing the relevant tools and services of the RIPE NCC. The course also offers practical exercises. OVERVIEW OF TOPICS COVERED IN THE COURSE: - Routing Registry as a part of the RIPE Whois Database and the Internet Routing Registry (IRR) - Specifying routing policies using (RPSL) Routing Policy Specification Language and the RtConfig tool - IRRToolSet - Routing Information Service (RIS) - Routing Registry Consistency Check Project Please note that this is an advanced course. It will: - NOT teach the basics of routing - NOT teach the basics of RIPE Database operations, - NOT describe how to receive Internet resources from the RIPE NCC - NOT describe how to operate a Local Internet Registry (LIR) The target audience of the course are technical staff of LIRs: e.g. network operators, engineers etc. This course is not intended for administrative or management staff (e.g. Hostmasters) . It is assumed that all attendees will be familiar with Border Gateway Protocol routing and with the RIPE Database (i.e. creating/modifying objects). This course is based on interactive exercises in a local network set-up. Please bring your laptops equipped with the following: - A working Ethernet card, - Three meters of Ethernet cable, - A secure connection client, - A web browser. Please be prepared to share your laptop (or at least allow another attendee to "look over your shoulder") if necessary. The Routing Registry Training Course is conducted in the English language and is free of charge, since it is covered by the membership fee. More information about the Routing Registry Training Course can be found at: http://www.ripe.net/training/rr/ REGISTRATION: You can register for a Routing Registry Training Course at the following URL: http://www.ripe.net/cgi-bin/trainingform.pl.cgi Or by completing the registration form at the end of this e-mail and replying to <training(a)ripe.net> . In order to register for a Routing Registry Training Course you must be an employee of an LIR and either: - be an LIR contact - be confirmed by an LIR contact LIR contacts are those employees of an LIR who are registered with RIPE NCC as authoritative contact persons. It is expected that most of those interested in the Routing Registry Training Course will not be an authoritative contact person for their LIR, and therefore will be, refused by the course registration "robot". In order to be admitted to the course, a confirmation e-mail must be sent to <training(a)ripe.net>. Please approach the LIR contacts from your organisation personally, since the identity of LIR contacts is confidential, and the RIPE NCC is unable to divulge contact persons for any given LIR. Kind Regards, Training Services RIPE NCC **************************************************************************** COURSE DATES AND VENUES ======================== Date: Wednesday 18 May 2005 Time: 0900 - 1700 Location: London, United Kingdom AND: Date: Friday 17 June 2005 Time: 0900 - 1700 Location: Paris, France ***************************************************************************** REGISTRATION: To register for this Course, please use the LIR Portal or complete the registration via our website on: http://www.ripe.net/cgi-bin/trainingform.pl.cgi If you have any questions please do not hesitate to contact us at <training(a)ripe.net>.
