In computer networking, linear network coding is a program in which intermediate nodes transmit data from source nodes to sink nodes by means of linear combinations. Linear network coding may be used to improve a network's throughput, efficiency, and scalability, as well as reducing attacks and eavesdropping. The nodes of a network take several packets and combine for transmission. This process may be used to attain the maximum possible information flow in a network.

  • 网络编码是一种通过中继节点对接收到的信息进行编码来达到提高多播网络容量的技术。Rudolf Ahlswede, Ning Cai, Shuo-Yen Robert Li, Raymond W. Yeung在2000年首次提出网络编码的概念。 在右图的网络拓扑中,s节点试图向组播两条消息x,y。设每条消息占用的带宽为1,每个节点之间的网络带宽也为1,那么每个节点之间只能同时传输一条消息。线路cd上会需要同时传输x,y,这在一般的传输方案中是行不通的,所以需要网络编码在c处将x,y异或,合成一条消息然后发送。 * 在传统的数据传输技术中,中继节点只负责数据的存储转发,而基于网络编码技术的网络的中继节点在具备传统中继功能的基础上,会根据网络编码规则将接收到的信息进行线性或非线性处理再进行传播,这种做法最直观的优势是减少了传输次数。利用图论中最大流最小割原理论证了网络编码可以达到网络最大信息流。 * 网络编码的相关领域:信息论、图论、编码理论 (zh)
