Design for Configurability: Rethinking Interdomain Routing Policies From the Ground Up

Giving ISPs more fine-grain control over interdomain routing policies would help them better manage their networks and offer value-added services to their customers. Unfortunately, the current BGP route-selection process imposes inherent restrictions on the policies an ISP can configure, making many useful policies infeasible. This paper presents Morpheus, a routing control platform that is designed for configurability. Morpheus enables a single ISP to realize a much broader range of routing policies without requiring changes to the underlying routers or collaboration with other domains.
