网络编码的提出彻底地改变了计算机通信网络中的信息处理方式，其研究结合了信息论、计算机通信网络、

组播技术、多用户信息论和图论等很多方面的知识。文中简要介绍了网络编码的基本原理，线性网络编码的基本概念及其发

展，并且提出一种实现线性网络编码的算法。-Its research involves the knowledge about information theory, computer communication

networks, multicast technique, multiple user information theory and graph theory. In this paper, principle

of network coding, the concept and development of linear network coding are briefly presented, including a

new algorithm for implementing linear network coding.
