摘　　要：为了使IPv4网络与IPv6网络间能直接进行组播通信,设计了一种基于双核模式的组播过渡模型。在网络中先选取两个核节点,以它们作为根,建立两棵连接组播组中所有成员节点的彼此独立的共享树,然后将DNS-ALG与NAT-PT相结合,作为IPv4和IPv6网络之间的转换网关,部署在两个组播域的核节点之间,组成一个双核模式的组播过渡系统,用来集中处理IPv4组播域与IPv6组播域之间的组播通信。In order to make IPv4 network and IPv6 network to direct muhieast communication, this paper designed a transition multicast model based on dual-core mode. First author selected two cores in the network as roots and established the two sharing trees that independent of each other to connect multicast group members in all the nodes, and then used the domain name system and application layer gateway（DNS-ALG） in combination with the network address transition and protocol transition （NAT-PT）, as the conversion gateway between IPv4 and IPv6 network; then deployed them between the core nodes of the two multicast domain, formed a transition muhicast system of dual-core mode to focus on deal with the multicast communications between IPv4 multicast domain and IPv6 multicast domain.
