如果要实现只将特定组播源发来的流量转发给相应的组成员,那么这样的组播机制,被称为特定源组播Source Specific Multicast(SSM)。 因为特定源组播(SSM)只将特定的组播源发来的流量,而不是任何源发来的流量转发给组成员,所以组成员在向路由器报告自己想要接受的组播流量时,除了明确指出组地址之外,还必须指出组播源地址...
边界网关组播协议 (BGMP) 是一种为域间组播提供路由选择的协议。 BGMP 协议原本支持“专用源组播”（SSM：Source Specific Multicast）。 为支持“任意源组播”（ASM： Any Source Multicast）， BGMP 为活动组播组建立了共享树，允许域在需要的时候建立具体源的， 域间的分支树以便信息分布。建立在 PIM...
源特定组播(SSM:Source Specific Multicast)是一种区别于传统组播的新的业务模型,它使用组播组地址和组播源地址同时来标识一个组播会话,而不是向传统的组播服务那样只使用组播组地址来标识一个组播会话。SSM保留了传统PIM-SM模式中的主机显示加入组播组的高效性,但是跳过了PIM-SM模式中的共享树和RP (Rendezvous Point...
3.2.1. Source-Specific Multicast Example Multicast addresses in the Source-Specific Multicast [SSM] range require a single unicast sender address for each multicast destination, so the source-filter specification provides a natural fit. In this example, a session member should receive only traffic se...
SSM-Source Specific Multicast(指定源组播) 对于某个多播组,进行指定源的加组行为,匹配上了源才接收组播流量,若组播流量不来自于指定的源,则丢弃流量。 在组播流量传输过程中没有不必要的泛洪和修剪。 在组播路由表中全部由 (S,G) 的形式表现,其中S为指定的组播源,G为相对应的多播组。
IP Multicast Address Management In the Internet Standard Multicast (ISM) service, applications must acquire a unique IP multicast group address because traffic distribution is based only on the IP multicast group address used. If two applications with different sources and receivers use the same IP ...

However, the efficient use of multicast requires architectural improvements. For example, the existing Any Source Multicast (ASM) specification is burdened with various protocol complexities and subse- quent deployment complications. The structurally simpler Source Specific Multicasting (SSM) model has great...
The chapter illustrates a new version of multicast called Source Specific Multicast (SSM). SSM means that a multicast group is identified not only by the multicast IP address, but also by the unicast IP address of the source. It is noted that most of the differences between Any Source ...
