PIM-SSM 的优势
PIM-SSM 的优势包括：
- PIM-SSM 将多播流量从单个源转发到子网。其他版本的 PIM 需要接收器订阅组。接收器只接收来自它所感兴趣的源的流量，但从发送至该组的所有源接收流量。PIM-SSM 要求接收方指定它们感兴趣的源，以避免接收不必要的流量。
与 PIM-SM 相比，PIM-SSM 效率更高，因为它会立即创建到源的最短路径树 (SPT)，而不是使用共享树。PIM-SM 要求将共享树根置于 RP，因为 IGMPv2 接收器不会在其成员身份报告中表达源信息。多播流量通过 RP 从源传递给接收器，直至最后一跳路由器 (LHR) 获知源地址，此时它将切换到 SPT。
PIM-SSM 使用 IGMPv3。由于接收方订阅源和组，因此 RP 和共享树是不必要的；仅使用 SPT。在 OS10 系统上，可以将 PIM-SM 与 IGMPv3 配合使用，以实现相同的结果，但 PIM-SSM 能够免去不必要的协议开销。
