传统的网络编解码算法需要进行线性运算，只适合在电域中实现。而当前全光器件的发展已经能够实现逻辑运算和移位操作。为了将网络编码引入到全光组播网络当中，文章研究了生成网络编码组播树的算法，以及适合于光网络编码的编码向量选取方法，并对所提出的算法进行了仿真分析。结果表明，将网络编码应用于全光组播中能够显著提高组播性能。

Owing to the need for performing linear operation,the traditional network coding/decoding algorithms are only suit-able to be applied in the electric domain,while thanks to the development of the current all-optical devices,it is possible to re-alize logic calculus and shift operations.In order to introduce network coding into all-optical multicast networks,this paper studies the algorithms for generating network coding multicast trees and the methods for selecting the coding vector appropriate for optical network coding and simulates and analyzes the presented algorithm.The results indicate that the application of net-work coding to all-optical multicast can significantly improve the multicast performances.
