基于多播的网络编码研究

最大流最小割的理论决定了网络的最大吞吐量,网络编码可以使这一理论在单元多播的网络环境下得以实现,其核心思想是在网络的中间节点引入编码功能,对收到的数据包进行相应编码后再转发出去,有别于传统网络的简单存储和转发操作.文章介绍了网络编码的原理、优势,分析了线性网络编码理论,并对其构造方法进行了改进,降低了复杂度.

The Research of Network Coding Based on Multicast

The famous max-flow min-cut theorem determines the maximum throughput of a net work,and the network coding can make this theorem realized in multicast network environment,its primary thought is coding at the middle notes,which receiving the data passage and employing relative process before forwarding it,that's difference from the traditional process by single conservation and forward.In this paper,principle of network coding,the analysis of linear network coding are briefly presented,including a refinery l...
