Abstract

Most existing overlay multicast approaches assume a singlehomed model, where each overlay node has a unique access link in the physical network. This assumption is usually not applicable to the routing problem in multicast service overlay network, which may comprise multihomed multicast service nodes(MSN). We address this issue by proposing not only a multihomed proxy model but also a two-phase solution to the routing problem under this model. First we choose a proper physical path for each overlay link based on the current network status and the routing policy. Then the routing process calculates the multicast tree according to the previous selection. Through simulations, we prove that our approach makes the overlay multicast routing more efficient in a multihomed environment.
