摘要
IP多播最早实施方案依赖于尽力而为方法 (BestEf forts)和用户数据报UDP(UserDatagramProtocol) ,所以不能保证多播数据流的可靠传输 ,参入的路由器不仅要处理网络中共有的动态拓扑结构变化 ,而且还必须处理作为成员加入或离去的动态主组。所以其负担特别重 ,极易发生网络阻塞问题。本文提出了一种“多播 +单播”方式 ,即能有效地减轻路由器的工作负担 。
The early IP multicasting was first put in practice mainly depending on best efforts and UDP, it can't ensure the credibility of multicasting data-stream. The joined Routers deal with not only the common changes of dynamic-topological structure but also the join-and-leave of the dynamic group for users. As a result, the network is easily to be blocked. The paper proposes a scheme of multicast and unicast to efficiently solve the problems mentioned above.
