Abstract
Researchers have proposed the Core Based Trees (CBT) and Protocol Independent Multicasting (PIM) protocols to route multicast data on internetworks. The performance of these protocols is examined in the Distributed Interactive Simulation (DIS) environment using the OPNET network simulation tool. The simulation results provide measures of important performance metrics including end-to-end delay, network resource usage, and join time. The size of the tables containing multicast routing information and the impact of the timers introduced by the protocols are also examined. Suggestions are offered to improve PIM Sparse while retaining the ability to offer both shared tree and source-based tree routing.Keywords
