针对将网络编码理论与现有因特网融合时存在的问题,设计了网络编码感知的新型网络结构,对现有数据转发设备即路由器进行了功能扩展,提出了一种新颖的分组等长化方案——串行组装法。利用排队论对串行组装法对编码节点的性能影响做了数值分析,并与最大长度填充法进行了对比。仿真结果表明,串行组装法在开销引入、节点处理时间、系统负荷率和排队长度等方面均优于最大长度填充法。
Aiming at the existing problems in the integration of network coding theory with the existing Internet, a new network structure of network coding is designed and the existing data forwarding equipment, that is, the router is extended in function. A novel packet equalization scheme is proposed - Serial assembly method. Using queuing theory, numerical analysis of the effect of serial assembly method on the performance of coding nodes is made and compared with the maximum length filling method. The simulation results show that the serial assembly method is superior to the maximum length filling method in terms of overhead introduction, node processing time, system load rate and queue length.
