An interface-based anycast routing table summary establishing algorithm

Anycast use the same address pool with unicast, but its routing table is difficult to converge for anycast servers’ dispersive location, and this leads to low efficiency of packet forwarding. This paper proposes an algorithm which can decrease the anycast routing table entries count by converge them based on interfaces. Analyses and experiment shows this algorithm performance is improved in packet forwarding. And this algorithm is routing loop-free as discussed in this paper. But it has limitation in network topology that must be applied in point-to-point network but not point-to-multipoint.
