Adding Topology Information to the Scalable Reliable Multicast Protocol

Abstract

This paper presents a new Scalable Reliable Multicast (SRM) protocol with Topology information, referred to as TSRM. To provide reliable service for multicasting, several reliable multicast approaches have been proposed. SRM is a typical example which adopts a timer-based approach to provide reliable delivery. TSRM enhances reliability and scalability of SRM by partitioning locations of session members into logical topologies. A receiver in TSRM dynamically configures timers of issuing negative acknowledgements (NACK) and repair packets based on the logical topology dynamically constructed from control messages. Simulations are performed to justify the improvement by comparing the performance of TSRM with that of SRM.
