Source-specific routing

Abstract : Source-specific (or source address-dependent) routing is a routing technique where routing decisions depend on both the source and the destination address of a packet. Source-specific routing solves some difficult problems related to multihoming, notably in edge networks, and is therefore a useful addition to the multihoming toolbox. In this paper, we describe the semantics of source-specific packet forwarding, and describe our implementation of a source-specific extension to the Babel routing protocol --- to our knowledge, the first complete implementation of source-specific routing ---, including a disambiguation algorithm that makes our implementation work over widely available networking APIs. We further discuss interoperability between ordinary next-hop and source-specific routing. Our implementation has seen a moderate amount of deployment, notably as a testbed for the IETF Homenet working group.
