摘　　要：近年来 ,可靠组播拥塞控制已成为组播研究的活跃领域 .本文讨论了可靠组播拥塞控制中存在的关键问题 ,分析了当前主要算法的特点 ,并针对其中存在的不足 ,提出了一种新的基于速率的组播拥塞控制算法 ,改善了拥塞控制的动态性和公平性 ,提高了组播会话的吞吐量 .In recent years,the research on congestion control for reliable multicast is one of the most active fields in the multicast protocol research.In this paper the principal problems of congestion control for Internet multicast are presented and the solutions and difficulties of solving these problems are discussed.Finally a novel rate-based multicast congestion control algorithm is given to improve dyamics and fairness of previous algorithms as well as the throughout of reliable multicast session.
