摘要
在Ｉｎｔｅｒｎｅｔ差错恢复技术及前向纠错（ＦＥＣ）编码的基础上，分析了可靠组播（Ｍｕｌｔｉｃａｓｔ）应用中采用ＦＥＣ进行差错恢复的性能，并提出一种基于ＦＥＣ的自适应可靠Ｍｕｌｔｉｃａｓｔ协议．结果表明，在通常的网络环境中，采用结合ＦＥＣ编码的混合ＡＲＱ差错恢复方式，能够降低可靠Ｍｕｌｔｉｃａｓｔ通信的平均分组传送次数，减小分组重传时间，从而提高数据吞吐量，而且在通信过程中根据网络状况动态地改变预发送纠错分组数。
Based on the error recovery technology and forward error correction coding in Internet, the performance of a reliable multicast protocol using FEC was investigated. The results show that hybrid ARQ can decrease the average transmission number of a packet and improve the throughput of a multicast application. Based on it, an adaptive FEC protocol for reliable multicast was also proposed to obtain a combination of efficiency and reliability.
