Route Flap Damping is back ?

obo — Thu, 10 Mar 2011 20:32:43 +0000

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

BGP is one of the key protocols that are used on the Internet today. Despite of its importance, the security of BGP is still a concern. Several solutions to improve the security of BGP have been proposed by the research community :

Simplifying BGP

During the last week, two recent IETF drafts have proposed to simplify some important aspects of the operation of BGP.

SimBGP with AddPaths support

vvandens — Wed, 21 Oct 2009 12:00:31 +0000

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

obo — Tue, 15 Sep 2009 09:42:25 +0000

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.

Analysis of paths selection modes for Add-Paths

vvandens — Tue, 07 Jul 2009 15:04:34 +0000

This document is aimed at discussing the various alternatives for the
selection of the paths that are to be advertised with add-paths. The
goal is to summarize the properties of those selection methods
depending on which application they are used for.

Graceful BGP session shutdown

pfr — Wed, 24 Jun 2009 08:16:09 +0000

This draft describes operational procedures aimed at reducing the
amount of traffic lost during planned maintenances of routers,
involving the shutdown of BGP peering sessions.
