Virtual multi-homing: On the feasibility of combining overlay routing with BGP routing

Abstract

This paper proposes a framework called Virtual Multi-Homing (VMH) to achieve loose source-based path selection and improve inter-domain path diversity. VMH is based on the concept of Virtual Peering and Multi-Homing Overlay to set up flexible inter-domain relationships. By interacting with BGP whenever possible, VMH can achieve scalable inter-domain route discovery without introducing duplicate work. In addition, VMH is a complementary approach to the existing Internet routing infrastructure and can be incrementally deployed. © IFIP International Federation for Information Processing 2005.
