航天测控通信中越来越多的点对多点业务数据采用指定源组播（ Specified Source Multicast， SSM）技术进行传输。对指定源组播和IGMP v3（ Internet Group Management Protocol）协议概念进行了简要介绍，论述了实现指定源组播可通过定源组播映射和软件编码两种方法，分析得出采用软件编码方法易于实现和维护的结论，并给出了Windows XP 操作系统下的软件代码。通过仿真和航天测控通信IP网实际应用，验证了软件编码方法的预期效果。

In the Space TT&C Communication,Specified Source Multicast (SSM) is used in more and more data-transmitting service,which transmits information from one source to several destinations.Firstly,the concept of Specified Source Multicast and IGMP v3 is described.And then,this paper introduces the implementation methods for SSM,ssm-mapping and software coding.It is concluded that software coding is easy to implement and maintain,and the software code is given for Windows XP.Simulations and actual applica-tions in the Space TT&C communication network show that the method is effective.
