Abstract This paper presents an approach to improve interdomain connectivity in the Internet. This novel concept deploys inter-domain routing functions on two different time scales. The innovative Fast Scoped Rerouting approach operates on a fine granular time scale and regular BGP is used on a coarse granular time scale. The overall concept intends to reduce the amount of globally visible BGP update messages and also provides an alternative path in case of failure. Thus, this novel approach improves the Internet s ability to derive a coherent view of its topology on the coarse time scale.
