摘　　要：针对目前卫星转发器资源日益紧张的现状提出在卫星通信网中采用IP组播技术进行缓解的一种方法。首先对IP组播技术的各种协议进行了简要的分析和论述,其次根据实际的系统应用分别搭建了平面IP组信号播传输测试系统和卫星IP组播信号传输测试系统,并对上述两个系统进行了测试和评估,最后对卫星通信网中IP组播技术的应用提出了进一步的改进要求。The method based on IP multicast technology is advanced in the satellite communication network for the limited transponders resources.First of all,several IP multicast technology protocols are analyzed and introduced in a simple way,secondly,the planar testing system and the satellite testing system for IP multicast signal transmission are built on the practical system application,which are tested and evaluated,and then the follow improved measure in the application of IP multicast technology in satellite communication network is proposed.
