An efficient and easily deployable QoS-based routing scheme for online Internet multicasting

摘要

With the advent of multimedia applications, the support of online multicasting with quality of service guarantees has gained considerable attention in the field of communication networks and distributed system. Online multicasting requires the support of online join and leave operations. In this paper, a new Simple and Efficient Low-cost Delay-bounded Online Multicasting (SELDOM) heuristic is proposed. SELDOM is particularly tailored to networks in which group membership changes frequently. SELDOM supports two modes of operations: Non-rearrangeable and rearrangeable. The scheme handles join requests dynamically by determining the least-cost path which satisfies the Required delay-bounds to which the new group member is to be attached.
