摘要
在可靠组播的实现中要解决的关键问题之一是如何进行快速有效的差错检测和恢复,主要有重传和纠错两类机制。文章介绍了这两类机制的研究现状,从模型特点、网络负荷、适用情况等不同角度进行分析,讨论了本地重传及其范围策略。
One of the most important technologies in reliable multicast implementation is how to detect and recover error efficiently and quickly. There are two mechanisms: repeat and error correction. This paper presents a survey on them focusing on their features and applications. Local recovery and scooping strategy are introduced. At last, it discusses some reliable multicast protocols.
