Abstract

As an extension of NSMP (neighbor supporting multicast protocol), PatchPSMP not only inherits the advantages of NSMP [Seungjoon Lee et al., 2000] and PatchODMRP [Meejeong Lee et al., 2001], but also has its own characters. Therefore, PatchPSMP has the following characters: (1)its route setting up and evaluation policy is same as that of NSMP; (2)its local recovery method is same as that of PatchODMRP; (3)it defines the unforwarding neighbor of forwarding nodes as pool nodes to collect the route information from its received data packets to reduce its local route recovery scope further. When a forwarding node finds a link failure between it and one of its upstream nodes, it floods out an ADVT packet. A pool node can answer its received ADVT packet when it connects to the wanted sources defined in the ADVT packet. By the simulation, we compare the performance of these protocols. PatchPSMP outperforms the others.
