一种基于SSM模型的IPv6组播地址分配方案

AN SSM MODEL-BASED IPv6 MULTICAST ADDRESSES ALLOCATION SCHEME

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。

Currently,more of the multicasting services use the static allocation of the multicast addresses,in light of this status quo,proceeding from IPv6 source-specific multicast （SSM）model,we present a host-based multicast address assignment （HBMAA）scheme usingSSMmodel adapting to fast multicasting services publishing needs,this makes the host of multicasting source can dynamically obtain a groupof multicast addresses while having applied the unicast address,so that simplifies the allocation of multicast addresses.Besides,by applyingDHCPv6-based multicasting services authentication validation architecture （SSVA）to the assignment scheme,we establish for the multicastaddresses of the host the corresponding dynamic multicasting verification strategy,enable the multicasting service possesses better security andcontrollability.
