Abstract :
Researchers have proposed the core-based trees (CBTs) and protocol independent multicasting (PIM) protocols to route multicast data an internetworks. We compare the simulated performance of CBT and PIM using the OPNET network simulation tool. Performance metrics include end-to-end delay, network resource usage, join time, the size of the tables containing multicast routing information, and the impact of the timers introduced by the protocols. We also offer suggestions to improve PIM sparse mode while retaining the ability to offer both shared tree and source-based tree routing
