摘　　要：传统网络多播路由编码方法采用多播分布树进行编码,但链路容量遭遇瓶颈,致使编码节点较多,导致浪费带宽资源的问题。在此提出基于Koetter指数时间的网络多播路由改进编码算法对编码软件进行设计,分析多播路由的总体设计,通过数据包编码转发模块在多播拓扑不相交路径上进行编码和转发多播数据包,利用输入模块实现网络多播路由和上游节点的信息交换,通过开关仲裁模块判断能够向特定输出端口传输信息的输入端口,利用死锁控制模块对出现死锁现象的路由节点进行检测,一段时间后使多播路由恢复正常的数据交换,通过输出模块对数据的输出进行管理。以降低带宽资源为目的,采用Koetter指数时间算法实现网络多播路由编码,并给出编码的详细代码。实验结果表明,所提方法不仅节省网络资源,而且显著降低多播路由时延,增强网络吞吐量。The traditional network multicast routing coding method uses multicast distribution tree to code,but it is easy for the link capacity to meet with bottleneck,which may result in more coding nodes and bandwidth resource waste. The improved coding algorithm of network multicast routing based on Koetter index time used to design the encoding software is proposed. The overall design of the multicast routing is analyzed,in which the data package coding transmitting module is used to code and transmit the multicast data package on the multicast topological disjoint paths,the input module is used to implement the information interchange between network multicast routing and upstream node,the switch arbitration module is used to judge the input port which can transport the information to the specific output port,and the deadlock control module is used to detect the routing nodes with deadlock phenomenon. After a period of time,the multicast routing can return to normal data exchange,and the data output is managed through the output module. In order to reduce the bandwidth resource waste,the Koetter index time algorithm is adopted to realize the network multicast routing coding. The detailed code of the coding is given. The experimental results show that the proposed method can save the network resources,greatly reduce the multicast routing delay,and increase the network throughput.
