Source management routing scheme called SMR is a new approach that provides a backup routing path for BGP on AS-level. In SMR, each AS in the virtual ring just is defined by a node which owns a unique identifier. It is a novel way to integrate some physical topology into virtual topology to shorten the routes greatly. And then, the authors present a theoretical model of SMR to describe the routing mechanism and the impacts on the routing performance. They evaluate the performance of SMR by simulations on a real BGP topology. In the case of each AS only maintaining a route to one virtual neighbor, SMR still provides a path to destination with low overhead.
