ABSTRACT
The limitations of BGP routing in the Internet are often blamed for
poor end-to-end performance and prolonged connectivity interrup-
tions. 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-
sive measurements of paths between nodes in a large content distri-
bution network, we compare the relative benefits of overlay routing
