大规模多播应用中差错控制机制的研究

An Error Control Scheme for Large scale Multicast Application

综述了现存差错控制机制在处理大规模多播业务时的优缺点，并针对仍然存在的问题提出了一种新的适应于大规模多播业务的差错控制机制。除了具有良好的局部恢复性能外，本机制较好地实现了与现有 Ｉ Ｐ 模型的融合，降低了恢复时延，减少了重复恢复现象的发生，适应群组成员和拓扑结构的动态变化。

This paper first discusses the performance of existing schemes in dealing with large scale multicast application. Then, a new control scheme is introduced which adapts to the large scale multicast applications. Besides providing good local recovery, this scheme integrates well with the current IP model, shortened the recovery latency, provides fewer duplicates than other schemes, and adapts to the dynamic changes of the group membership and topology.
