Abstract: Protocol Independent Multicast - Sparse Mode (PIM-SM) is the preferred multicast routing protocol currently. But it has the deficiency of high overhead of control messages and it needs to be improved. Stochastic Petri Nets is a soft computing technique that has been widely used in the area of performance evaluation. We improve PIM-SM protocol in this paper by use of Stochastic Petri Nets. The improvement mainly focuses on Register message, Join/Prune message and Bootstrap message. Experiments and analysis using Petri nets suggest that our improvement results in better performance than the current standard of PIM-SM protocol.
