摘要： A method for filtering multicast sources, so that when the multicast routing protocol is based on the Source-Specific Multicast (SSM) model, resource consumption of inquiry routers can be reduced and the multicast packet forwarding efficiency can be improved. In the present invention, the inquiry router determines whether it is the Any-Source Multicast (ASM) model or the SSM model that the multicast routing protocol running in the network is based on. If it is the ASM model, maintain the source filtering method in the related art. If it is the SSM model, cancel the source filtering process or only performing the source filtering process in the inclusive mode. In the situation that only the source filtering process in the inclusive mode is performed, the additional filtering mode switching function or static configuration by software guarantees that the inquiry router is only in the inclusive mode, thereby avoiding the mode switching.

摘要： A method for implementing multicast in a Virtual Router-based Virtual Private Network (VR-VPN), including: establishing a local multicast tree in each VPN site and a Service Provider (SP) multicast tree connecting each VPN site; setting a Proxy Source/Rendezvous Point (RP) for a multicast source on each VR; the multicast source transmitting multicast data to the Proxy Source/RP on an ingress VR, the Proxy Source/RP forwarding the multicast data to a local receiver along the local multicast tree, and transmitting the multicast data to an egress VR along the SP multicast tree after encapsulating the multicast data; the egress VR de-encapsulating the multicast data and discarding the multicast data or forwarding the multicast data to the local site according to local state. The present invention may improve the transmission efficiency, and reduces multicast on backbone routers, thereby improving the scalability of the network.

摘要： A system and a method for a Mobile Host (MH) implementing a multicast service, wherein each MH corresponds to a Dynamic multicast Agent (DMA); the DMA needs to implement dynamic switch according to the path that the MH passes when moving; if the DMA of the MH is switched to the MSA of the current multicast sub-network, the MH joins the multicast group directly, thereby optimizing the transmission path of the multicast. The present invention can not only make the multicast distributing tree reconstruction caused by moving of the MH less frequent, but also avoid a too long tunnel form between the DMA and the MSA of a foreign multicast sub-networks, thereby optimizing the transmission path of the multicast packet. The present invention can also make the best use of network resources, and prevent the DMA from becoming the bottleneck of network communication while avoiding tunnel congregation.
摘要翻译：一种用于实现多播服务的移动主机（MH）的系统和方法，其中每个MH对应于动态多播代理（DMA）; DMA需要根据MH在移动时通过的路径来实现动态切换; 如果MH的DMA切换到当前组播子网的MSA，则MH直接加入组播组，从而优化组播的传输路径。本发明不仅可以使由移动MH引起的组播分发树重构较少频繁，而且可以避免外部组播子网的DMA与MSA之间的过长的隧道形式，从而优化传输路径组播数据包。本发明还可以充分利用网络资源，防止DMA成为网络通信的瓶颈，同时避免隧道聚集。
