Chord6: IPv6 Based Topology-Aware Chord

Chord, in its original design, does not take into account physical network topology, thus resulting in high routing latency and low efficiency. As the entire Internet is being currently upgraded from IPv4 to IPv6 worldwide, we devise a smart scheme to exploit the IPv6 address hierarchical feature, so as to construct an efficient version of Chord dubbed Chord6. Simulation results have shown that our method can significantly reduce inter-domain traffic that causes the long routing latency. Another advantage of our scheme is that it is very simple and barely modifies the original Chord
