Abstract
Recently an alarming trend for the global routing table's growth factor in the interdomain IP backbone [2] shows that Internet inter-domain routing scalability becomes an issue again. It is widely agreed upon that the rapid global routing table size growth is mainly due to the growth in the number of ASs and the wide deployments of multihoming and traffic engineering. These popular commercial practices deaggregate the routing prefixes. Compact routing has been proposed to tackle routing scalability issue. This paper suggests a new compact routing scheme which achieves a smaller average stretch, by accounting for the nearby scale from topology at the inter-domain level. At the same time, it guarantees that routing table size has a sub-linear growth speed with respect to the network dimension.
