摘要 组播应用使光网络的带宽资源日趋紧张。网络编码具有提高带宽利用率、提升网络的吞吐量、改善网络负载均衡等优点。分析了网络编码的特点及其编码代价、传统路由面临的问题,讨论了将网络编码引入光组播,优化光组播路由、提高网络吞吐量和资源利用率的研究方法。 Multicast applications have become an important issue for the optical network bandwidth resources.Network cod-ing can improve the utilization of bandwidth resources,the throughput of network,and balance the traffic load of the net-work.The network coding,the cost of coding and the problem of traditional routing are discussed in the paper.Further-more,the network coding technology is introduced into the optical multicast to optimize the optical multicast routing,to in-crease the throughput of network,and to improve the network resources utilization.
