中文摘要：
为了解决当前的 IP 的问题，多点传送它包括差的内部域的 many-to-many 组支持，对的安全危险和相关性特定多点传送基础结构，在 IPv6 网络的一个活动可存取的关上的多部分组(MACMPG ) 通讯协议被建议。由扩大单身的来源多点传送协议，为越过领域的多部分组通讯的通讯隧道被建立。把 CGA 基于 IPv6，安全的关上的组通讯计划被设计。仅仅限制到授权的发送者和接收装置并且仅仅信任了路由器的 multicast 交通的存取被允许是 MACMPG 树的支化点。由通道机制， MACMPG 交通能越过 non-MACMPG 路由区域被播送，并且活动节点能遥远地加入这个组并且在领域之间自由地漫步，它在特定的 IP 上消除相关性多点传送路由。
英文摘要：
To solve the problems of current IP multicast which includes poor inter-domain many-to-many group support, security vulnerabilities and dependency to specific multicast infrastructure, a mobile accessible closed multi-part group （MACMPG） communication protocol in IPv6 network is proposed. By extending the single source multicast protocol, the communication channel for multi-part group communication across domains is established. Based on lPv6 CGA, the secure closed group communication scheme is designed. The access to the multicast traffic only confined to the authorized senders and receivers and only trusted routers are allowed to be the branch points of MACMPG tree. By tunneling mechanism, the MACMPG traffic can be transmitted across non-MACMPG routing area, and the mobile nodes can join the group remotely and roam freely between domains, which eliminates the dependency on specific IP multicast routing.
