[routing-wg]Announcement Routing Registry Training Courses
by RIPE NCC Training Services 07 Feb '06

07 Feb '06

Dear Colleagues The RIPE NCC Training Services Department invites you to register for one of our upcoming Routing Registry Training Courses: Date: Friday 10 March 2006 Time: 0900 - 1700 Location: Kiev, Ukraine Hosted by: Hosted by EDU Incom And Date: Tuesday 11 April 2006 Time: 0900 - 1700 Location: London, United Kingdom And Date: Friday 5 May 2006 Time: 0900 - 1700 Location: Valletta, Malta And Date: Friday 12 May 2006 Time: 0900 - 1700 Location: Amsterdam, Netherlands And Date: Friday 19 May 2006 Time: 0900 - 1700 Location: Moscow, Russian Federation 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 course is free of charge. We provide lunch and printed training materials. We do not cover any of your travel expenses or accommodation. We give all of our training courses in English. You can find more information about the course at: http://www.ripe.net/training/rr/ How to register: --------------------- You can register up to two people from your LIR for each course. (If there are places left nearer the time of the course, you can register more people). To register for this course, you can either use the LIR Portal at: https://lirportal.ripe.net/lirportal/training/course-list.html Or the online registration form on our website: http://www.ripe.net/cgi-bin/trainingform.pl.cgi If you have any questions, send an e-mail to <training(a)ripe.net>.

[routing-wg]bgpinspect stats fixed...
by Manish Karir 07 Feb '06

07 Feb '06

Just wanted to drop a short to let everyone know that we did fix the annoying bug that was causing the bgpinspect global summary statistics to be zeroes(or inaccurate). These should be working correctly now. I would recommend that people periodically check out the top20 lists. If your AS suddently shows up there in terms of activity, there might be some inherent problem that is responsible for the instability. The "Most Origin AS changes" query results should be taken with a grain of salt, this currently does not correctly account for MOAS behaviour. thanks manish

[routing-wg]Modelling a large ISP network with C-BGP
by Olivier Bonaventure 04 Feb '06

04 Feb '06

Dear All, C-BGP is an efficient and open-source simulation tool that allows to simulate the behavior of the intra- and interdomain routing protocols in large ISP networks. C-BGP is able to simulate networks with thousands of routers. A key feature ofco C-BGP compared to other simulators is that it is able to support the complex routing policies that are used by ISPs. Thanks to the support of France Telecom R&D, we have been able to use C-BGP to reproduce the behavior of BGP in a large Tier-1 ISP network. For this analysis, we have developped several tools to automatically convert the BGP configurations of Juniper (JUNOS) and Cisco (IOS) routers, the IGP topology and the BGP routes in the C-BGP format. With these tools, any network operator can easily build a C-BGP model of his/her network. With such a model, it is possible to perform different types of analysis on the ISP network, such as : - predicting the flow of the traffic through the network or determining the traffic matrix based on Netflow data (see article in January issue of ACM SIGCOMM Computer Communication Review) - predicting the impact of adding a new peering link on the BGP routes selected by the routers (see article in Nov/Dec issue of IEEE Network Magazine) - predicting the impact of link or router failures on the ISP network You can obtain C-BGP, the conversion tools and several papers describing the utilization of C-BGP to model an ISP network or compute traffic matrices from : http://cbgp.info.ucl.ac.be The website also contains several examples, such as a complete C-BGP model of the Abilene Network based on their publically available JUNOS configurations files. We believe that C-BGP could be very useful for ISPs willing to optimise the distribution and the selection of the BGP routes in their network. Comments, suggestions and questions from network operators are more than welcome. Best regards, Bruno Quoitin, Sebastien Tandel and Olivier Bonaventure -- CSE Dept. UCL, Belgium - http://www.info.ucl.ac.be/people/OBO/
