Route Flap Damping is back ?

Thu, 03/10/2011 - 23:32 by Olivier Bonaventure • Categories:

One of the problems faced by BGP routers today is the BGP churn, i.e. the number of messages that they have to process. Measurement studies have shown that a small fraction of the prefixes are responsible for a large fraction of the BGP messages that are received by BGP routers. Furthermore other studies have shown that the destination prefixes that carry lots of traffic usually have stable BGP routes.

Securing BGP

SimBGP with AddPaths support

The original SimBGP simulator available on BGPVista website is a lightweight event-driven simulator developped by Jian Qiu.
The extended version of SimBGP we developped provides support to the Add-Paths BGP extension, with several selection modes available. We also provide the set of validation tests that were used during the development process.

Two new Internet topology datasets

Tue, 09/15/2009 - 12:42 by Olivier Bonaventure • Categories:

The research community has developed many tools to try to map the topology of the Internet. As the Internet is a decentralised network composed of more thank 30000 different networks, it is very difficult (and perhaps impossible) to obtain a detailed map of the network. The most widely use to infer the router-level topology of the Internet is traceroute.
