Distributed QoS-aware source-specific multicast routing protocol

A distributed QoS (quality of service) -aware source-specific multicast routing protocol—DQSSMR is proposed to increase the successful join ratio and lower the overhead of the control message in QoS required multicast routing. By an improved searching strategy, the cost of message control is reduced and the successful join ratio is increased. The network load is balanced due to the distributed routing operation and the scalability is enhanced further because of the usage of SSM (source- specific multicast) service model in DQSSMR. The analysis results indicate that DQSSMR performs as expected.

基于IGMPv3和PIM-SSM协议的源特定组播技术的研究

描述了基于IGMPv3和PIM-SSM协议的源特定组播模型。在网络实验环境上进行了实验,分析了基于IGMPv3和PIM-SSM协议的源特定组播的工作过程,得出源特定组播可以和任意源组播良好共存。最后讨论了源特定组播模型的优缺点。

一种基于SSM模型的IPv6组播地址分配方案

针对当前组播服务多采用静态分配组播地址的现状,从IPv6特定源组播(SSM)模型出发,提出适应快速组播服务发布需求的基于自身配置的SSM模型组播地址配置方案(HBMAA),使得组播源主机可以在申请到单播地址的同时动态获取到一组组播地址,从而简化了组播地址的分配工作。此外,通过对该配置方案应用基于DHCPv6的组播服务真实性验证体系(SSVA),为主机的组播地址建立对应的动态组播验证策略,使组播服务具备了更好的安全性和可控性。
