Routing working groupp agenda and call for items
by Joao Damas 19 Apr '05

19 Apr '05

Dear all, with the new format of the RIPE Meeting at RIPE 50, the plenary (Monday-Wednesday) is the space where most presentation will take place, whereas the working groups are being geared towards being a space for discussion and development of work items leading to recommendations or problem statements. These may be derived from the talks taking place during the plenary and, if content is generated, would ideally result in RIPE Documents. With this in mind, following is the draft agenda for the routing working group at RIPE 50: - Administrativia: Minutes of previous meeting, Appointment of scribe, review of open actions, attendee list - Discussion space for the topics covered in talks: - Traffic engineering and the effect of business practices on the routing table - Route flap damping today in particular discussing the current RIPE Route flap damp(en)ing recommendations as described in RIPE Document 229 and - DDoS Detection & Mitigation Experience using Arbor/Peakflow & Cisco/Guard - Watch your Flows with NfSen and NFDUMP - Traffic Anomaly Detection, DDoS Mitigation, Coordinated Attack Fingerprinting should more time than available in the plenary be necessary for discussion At this time, also, suggestions for topics specific to routing are welcome for inclusion in the agenda Regards Joao Damas ISC

Networking 2005 includes a peer-reviewed program of technical sessions, panels, tutorials, and workshops. The five-day program starts with cutting-edge tutorials on a range of hot topics, including sensor and ad hoc networks, delay-tolerant networks, optical networking, and quality of service. Throughout the week there will be keynote talks by research and industry leaders, including Peter Carbone, Vice President of Next-Generation Architectures, Networks and Technology at Nortel Networks. Panels will cover issues of immediate relevance to both industry and research alike, including cross-layer design issues. The week will be rounded out with a series of workshops on critical issues on networking today, including problems of rapid configuration, modeling, and middleware.

announce prefix
by Wycliffe Bahati 31 Mar '05

31 Mar '05

Hi all Do some providers out there have a problem accepting announcements that do not have route objects created. I am considering a fact that an ISP could have a /16 however it has not assigned this address to anybody, however they need to announce this in order to assign this to there customers.

CfP: Interdomain Routing Workshop (IDRWS), May 6-7, 2005.
by Henk Uijterwaal 29 Mar '05

29 Mar '05

(Apologies for duplicate messages) The tremendous growth of the Internet is causing concern among researchers and practitioners about scalability and convergence of the current routing architecture. The concern arises from real world problems caused by configuration mistakes, routing anomalies, conflicting policies, protocol limitations and so on. Furthermore, demands for traffic engineering, and new services such as route control are being controversially discussed within the community. A lot of efforts are focused on routing enhancements or even new protocol generations. To help researchers to act jointly with current operational problems, a workshop is organized with focus on the next steps towards the near-term future (next 5 years) of Inter-Domain Routing (IDR). This year IDRWS has a special focus on Inter-Domain routing security (e.g. requirements, solutions and experience) and especially asks people working in this area to participate on the workshop. The general goal of this workshop is to bring together a small, focused group of operators, vendors and researchers, to discuss in an open forum important mid- and long-term problems, security issues, network management tools, measurement techniques and router features. Especially, it is intended to talk about issues that operators feel will come up in the next years if we do not start to investigate problems now and begin to work on potential solutions. For the IDRWS we are looking for contributions that can range from academic ideas, monitoring strategies and tools, over reports about the current routing situation, best common operational practices, even to suggestions about protocol enhancements. Furthermore vendor feedback on implementation details or the presented ideas is more than welcome. Practical details: * Location: Clarion Hotel, Ringvagen 98, 10460 Stockholm (This is the same location as the RIPE50 meeting). * Deadline abstracts: April 18, 2005 * Notification of Acceptance: April 25, 2005 * Presentation duration: 15 - 30 min * Contact: <mailto:idrws-submission@tm.uka.de>idrws-submission(a)tm.uka.de * The workshop will take place at the 6th and 7th of May * Web: <http://www.idrws.org/>http://www.idrws.org/ * Registration fee: 30 euro's for those attending RIPE50, 50 euro's for all others, or the equivalent in SEK. The registration fee can only be paid in cash at the venue. The fee includes coffee and lunches on the days of the workshop. ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal(at)ripe.net RIPE Network Coordination Centre http://www.amsterdamned.org/~henk P.O.Box 10096 Singel 258 Phone: +31.20.5354414 1001 EB Amsterdam 1016 AB Amsterdam Fax: +31.20.5354445 The Netherlands The Netherlands Mobile: +31.6.55861746 ------------------------------------------------------------------------------ Look here junior, don't you be so happy.
