NANOG Meeting Presentation Abstract

Analysis of RIPE / RIS Project\'s BGP Data: CIDR at Work
Meeting:	NANOG23
Date / Time:	2001-10-23 2:45pm - 3:15pm
Room:	OCC East
Presenters:	Speakers: Cengiz Alaettinoglu, Packet Design Cengiz Alaettinoglu is a member of the Technical Staff at Packet Design. His current work includes analysis of and enhancements to BGP and IGP scaling and convergence properties. He was previously at the USC Information Sciences Institute, where he worked on the Routing Arbiter project. Cengiz co-defined the Routing Policy Specification Language along with the protocols to enable a distributed, secure routing policy system.
Abstract:	We analyze the BGP messages collected by the RIPE-NCC Routing Information Service. The data has been collected for about two years. It is much richer than the daily snapshots often used in analysis and helps us address more detailed questions than simply table size growth. For example, we can show the effectiveness of CIDR aggregation, or account for multi-homing and inter-domain traffic engineering more accurately. In short, we find that the routing table size growth is not exponential, CIDR is doing very well, and churn is decreasing. Most of the churn is due to the loss and re-establishment of BGP peerings, as well as policy misconfigurations (leaking routes, etc).
