| 摘 要： | ＩＰ组播基于“尽力传送”,不保证数据传送的可靠性。为组播提供差错控制的技术主要有：单播中的ＡＲＱ机制,无线电通讯中的ＦＥＣ码技术和两者的结合这些技术的策略和性能都不相同。本文将对这些技术进行介绍,并了讨论了它们在组播协议中应用的相关问题。

| Abstract: | Multicast provides "best effort delivery", which means it does not guarantee the reliability of data transportation. Some techniques supplement multicast in this aspect. Those techniques include ARQ scheme of unicast, FEC codes used in telecommunication field and combination of the two. They differ in strategy and performance. This paper overviews those techniques and discusses their application issues. |
