Abstract

Due to the mismatch between an overlay and its underlying physical network, the routing latency in existing DHT systems such as Chord and CAN is rather high. We note the fact that the IPv6 address hierarchical structure can aggregate route entries in Internet, and thus propose that nodes in an overlay can cluster together by taking advantage of the shared IPv6 prefix of specific length. While utilizing DHT systems themselves to store and retrieve the IPv6 prefix information, we adapt it to Chord and thus construct an improved version dubbed eChord. Analysis and simulation results confirm that eChord can significantly reduce routing latency.
