A TCP Friendly, Rate-Based Mechanism for NACK-Oriented Reliable Multicast Congestion Control (Preprint)

Abstract

In this paper, we describe ongoing work in adding congestion control extensions to an existing negative acknowledgement (NACK) oriented reliable multicast protocol. Our previous work adopted and used the concept of a dynamic worst path representative for equation-based rate adaptation at the multicast source and we have further refined this approach and present results here. We present an overview of these extensions implemented within a working reliable multicast protocol (mdp-cc) and we present simulation results. Our analysis of interflow fairness with TCP unicast sessions demonstrates friendly behavior across a set of scenarios and results with more dynamic flows show that the worst path representative approach adapts rapidly to changing congestion conditions.
