| 摘 要： | 本文在目前各种可靠组播传输协议的基础上,归纳构建了两类基本的可靠组播传输协议—基于确认(ACK)的和基于否定确认(NAK)的可靠组播传输协议.在典型的组播网络系统模型基础上,对这两类协议以及一种主要的改进协议在占用网络带宽和可扩展性方面的性能特点进行了定性的分析和比较.性能分析结果表明,基于否定确认且采用否定确认压缩策略(NAK Compression)的可靠组播传输协议成功传输组播数据包所需要的带宽较小,具备良好的可扩展性.

| Abstract: | Two types of basic reliable multicast transport protocol (ACK based and NAK based) are presented in the paper.Qualitative analysis of these two basic protocols and a modified protocol is given to exhibit their characters in scalability and bandwidth usage on a typical multicast network model.The analysis result shows that the reliable multicast transport protocol based on NAK with NAK Compression scheme consumes less bandwidth and exhibits perfect scalability. |

| Keywords: | reliable multicast transport protocol ACK/NAK NAK compression scheme |
