<title>Rate-based congestion control for many-to-many multicast ABR traffic</title>

Abstract

In this paper, we discuss issues of rate controlling many- to-many multicast connections. In particular, we present an end to end rate control algorithm for multicast ABR service in ATM networks. The algorithm is the extension of the SP- MRCA point-to-multicast congestion control algorithm proposed. The goal is to control the various multicast members input rates in order to achieve high bandwidth utilization without overflowing any queue along a multicast tree. We show that a multipoint-to-multipoint multicast connection can be viewed as a superposition of one-to-many multicast connections, and compute the multicast input rate for each multicast member separately. The algorithm proposed, called SP-MMRCA, inherits many of the properties of the point-to-multipoint SP-MRCA.
