提出了一种基于数据速率匹配调整的网络编码优化机制OMNR，通过对关联数据速率的线性规划函数的描述及控制网络数据传送转发状态的数据票参量的引入，机制在基于网络编码的多径路由上实现了数据速率的匹配编码；基于对反映目的节点数据解码状态的数据批次解码时延的概率检测，OMNR机制实现了多径路由上数据速率的匹配调整。在 OMNR 机制的数据传送中，路由选择中数据往返时延和网络编码中数据传送确认信息的实时测量在较大程度上保证了编码数据传送的可靠性。理论分析和模拟实验证明了模型的有效性和可靠性。

The network coding optimization mechanism OMNR(optimization mechanism for network-coding based on rate-match) was proposed. The mechanism achieves the rate match based on the solution of the linear programming func-tion on data transport rate and the introduction of the data ticket parameter in coding-aware multi-path routing. And the dynamic adjustment on rate match process was achieved by the probability detection of the decoding delay of data gener-ation that reflects data decoding state in destination nodes. The real-time measurement on the data transport round-trip delay in routing selection and acknowledgement information in network coding guarantees the data transport reliability. Theoretic analysis and simulation show the validity and reliability of the model.
