Executive Summary

This paper develops and studies a Traffic-aware Inter-Domain Routing (TIDR) protocol, which drastically improves the stability of the BGP-based inter-domain routing system. TIDR is designed based on two important Internet properties - the Internet access non-uniformity and the prevalence of transient failures. In TIDR, a network prefix is classified at an AS either significant or insignificant from the viewpoint of a neighboring AS, depending on the amount of traffic exchanged between the prefix and the neighbor (Including transit traffic).
