A network coding optimization is designed to improve PPP link performance in PDSN system. Based on the multi-link PPP bundle channel the network coding and decoding modules are given. The multi-user coopera tion communications group is introduced. Finally a simulation experiment is given to verify the feasibility and supe riority of the mechanism.%提出了一种基于网络编码的PDSN系统中PPP链路性能优化机制.设计了网络编码模块,多PPP链路捆绑信道,网 络解码模块和多用户合作通信组.最后进行了仿真实验简单验证了此机制的可行性和优越性.
