Distributed Route Servers: A novel internal BGP route distribution architecture

with 2 comments

Lately, I’ve been looking at solutions to avoid correctness issues that may arise in iBGP. These issues are explained in Tim Griffin’s et al., Sigcomm 2002′s paper.

In Pelsser_DRS_IEICE_200903, I proposed a solution relying on an overlay of distributed servers that compute routes on behalf of the routers. Today, each router computes for every prefix its own routes, based on a limited visibility of the routes. In this proposal, we rely on a different distribution of the route computation. Each server has full visibility of the routes for a subset of the prefixes. A server computes for its subset of the prefixes, the route to be used by every router of the domain. The server performs a per-router computation. Full routing visibility at the node performing route computation ensures iBGP correctness.

A presentation describing this proposal can be found here.

Customized BGP route selection (CRS)

without comments

In March, I presented Laurent Vanbever’s work called Customized BGP Route Selection (CRS) at the WIDE camp. This work is about using BGP MPLS/VPNs to advertise neighbor-specific BGP routes.

The presentation can be found here.

Internet Quota and Net Neutrality

without comments

Here is a reference to an all public position article from Olivier Bonaventure. The article is on the enforcement of Internet quota by Internet Service Providers. The article is in French. It highlights the dangers of quota on network neutrality. Dangers arise when these quotas are not applied indifferently to all services.
