| 摘 要： | 目前的组播协议在具体应用中存在实时性较低的问题,还不能较好满足网络电视、远程教育、视频会议等信息服务领域的需求,因此可以考虑一种优化协议的实现方法,它利用静态组播成员的静态特性,并根据一些组播应用中的时域组播树重叠的特性,缩短传统组播应用的延迟时间,以达到快速组播的目的。

| Abstract: | Various existing multicast protocols have the problem of relatively low real-time in some applications,nor do they well meet the requirements of information service domain such as IPTV,distance education and video conference,so an implementation method of protocol optimization needs to be considered.Making use of static characteristic of static multicast member and according to overlap feature of time domain multicast tree in some multicast applications,the method can decrease the delay of traditional multicast applications and achieve fast multicast.. |

| Keywords: | fast multicast static multicast member multicast shared tree multicast source tree PIM-SM SSM |
