Abstract
The limitations of BGP routing in the Internet are often blamed for poor end-to-end performance and prolonged con-
nectivity interruptions. Recent work advocates using overlays to effectively bypass BGP's path selection in order to
improve performance and fault tolerance. In this paper, we explore the possibility that intelligent control of BGP
routes, coupled with ISP multihoming, can provide competitive end-to-end performance and reliability. Using exten-
