在研究网络多方通信和IP多播寻址方法的基础上,提出了一种新的IPv6寻址方法,用来支持多播不能很好支持的小规模群组的多方通信.该算法利用IPv6的扩展头,设计了一个称作目的地址扩展头的IPv6扩展头实现这种寻址方法.此寻址方法介于单播和多播之间,在性能上接近于多播,路由上接近于单播,避免了多播和单播寻址方法在小规模群组多方通信上的不足,而且对现有协议的改变不大,为多方通信的应用提供了很好的支持.
Based on the research of multiparty-communication and IP multicast, a new IPv6 addressing method is proposed to support multiparty-communication applications with small-scale group. This algorithm utilizes the extension header of IPv6, an extension header called destination address extension header is designed. The new method is between unicast and multicast, which is similar to multicast on the performance and similar to unicast on the route. This method avoids the deficiency of the unicast and the multicast on the multiparty-communication with small-scale group. The new addressing method can support many multiparty-communication applications very well, but change the current protocol little.
