Performance Modelling of Multicast Protocols

This book provides analytical tools for assessing the improvements that can be made to existing modified or entirely new multicast protocols at an early stage of design. Specifically the work investigates the general properties of protocol independent multicast (PIM) variants. It quantifies and compares these PIM variants which include dense mode with state refresh mechanism (PIM-DMSR) dense mode with flood and prune mechanism (PIM-DMFP) source specific multicast (PIM-SSM) and sparse mode (PIM-SM) using control bandwidth overheads (CBO). The analytical models can be used to fine-tune and scale the performance of multicast protocols in terms of flood join prune and state refresh intervals which are usually given as ad hoc defaults in the Internet Engineering Task Force (IETF) documents.
