Core-Based Approach in Multicast Routing Protocols

The Core-based approach provides efficient management of multicast paths in dynamic environments, scalability and performance in multicast routing protocols. In this paper, we present a comprehensive analysis of this approach with emphasis on core selection. We review core-selection algorithms in the literature for their algorithmic structure and performance. Our study also involves an extensive computational and message complexity analysis of each algorithm, and a classification for their deployment characteristics and algorithmic complexities. To the best of our knowledge ours is the first paper providing such extensive comparative analysis of core-based multicast routing protocols.
