| 摘 要： | 在广泛部署和大规模应用IP层组播时,组播状态将超出路由器的性能极限。为了解决组播路由的状态可扩展性问题,提出了基于动态隧道的可扩展组播路由协议(DTSM)。该协议采用隧道方式消除了非分支节点状态。在状态容量充足时,该协议与传统组播协议效率相同。在状态容量不足时,自适应地调整转发树拓扑,以带宽和延时为代价进一步减少组播状态。仿真结果显示:该协议可以在不显著增加带宽和延时的前提下,使组播最大状态数减少一个数量级,可以有效地缓解组播状态压力。

| Abstract: | Multicasting states often exceed the router's capability due to wide deployment and extensive usage of IP layer multicasting.A dynamic tunneling based scalable multicasting routing protocol(DTSM) was developed to reduce the number of multicasting states connected to the router.The protocol eliminates non-branching node states by tunneling with sufficient state capacity,and achieves comparable efficiency to traditional multicasting.When the state capacity is exhausted,the protocol adjusts by adaptively tunne... |
