摘　　要：指定源组播在组播源已知的专用网络中有着优越的性能。通过对指定源组播实现中主机与路由器间的协议分析,阐述了Windows平台对指定源组播的支持方法。对于支持IGMPv3的XP及以上版本,给出了软件编码实现;对于不支持IGMPv3的Windows 2000,给出了SSM-Mapping及软件模拟实现IGMPv3协议的方法。通过测试以及实际应用,这几种方法都达到了预期的效果。Specified Source Multicast （SSM） has good performance when it is used in the specialized network with known multicast sources. In this paper, by analysing the protocol used for SSM between the host and the router, SSM under Windows platefom is described. The program coding is presented for Windows XP and the above version on which IGMPv3 can run. For Windows 2000 and the earlier version on which IGMPv3 cannot run, the ways by SSM-Mapping and IGMPv3 simulating are demonstrated. Tests and actual applications showed that that all these methods are effective.
