Updated agenda for routing-wg
by João Damas 04 May '05

04 May '05

Thursday, May 5, 9:00-10:30, Plenary room - Administrativia: Minutes of previous meeting, Appointment of scribe, review of open actions, attendee list - Discussion space for the topics covered in talks: Open floor, seeking input and discussion on: - Traffic engineering and the effect of business practices on the routing table - Route flap damping today - DDoS Detection & Mitigation Experience using Arbor/Peakflow & Cisco/Guard - Watch your Flows with NfSen and NFDUMP - Traffic Anomaly Detection, DDoS Mitigation, Coordinated Attack Fingerprinting - Thoughts about recommendations for BGP filters for IPv6 Presentation: - Active BGP probing. Lorenzo Colitti, RIPE NCC and University of Rome Tre Introduction/abstract: I and my colleagues at Roma Tre University have developed techniques that ISPs can use to find out how their prefixes could be announced in case of network faults and how other ASes treat their prefixes. Our techniques are based on active BGP probing and announcing large AS-sets, and have been successfully tested in the IPv6 Internet. Our subsequent announcement of tests on the IPv4 network caused a bit of a stir on nanog [1]. The tests were cancelled and we said we would first come out with a document explaining what we do and how we do it and then continue the discussion. A technical report is almost ready and we would like to get the discussion going.
