| 摘 要： | 在分析数据流关系的基础上,通过动态链表给无连接的IP网络增加一定的面向连接的特性,并结合跨层的思想在IP层对TCP报文首部进行跨层操作,提出了一个面向连接的并发多路径转发算法(CCFA).CCFA通过动态链表统计的不同流的比例关系,对不同流的流量特征进行分类,在多路径上对不同流量进行分流转发.最后通过NS2仿真实验研究了不同转发粒度的特点及相关的应用场合,结果表明CCFA以一定的存储开销为代价,获得了较高的转发性能,提高了带宽利用率,降低了端到端延迟,而且本算法易于在下一代网络的可编程路由器中部署使用.

| Abstract: | Based on the analysis of flow relationship of the CMP(concurrent multi-path),a connection-oriented CMP forward algorithm(CCFA) is proposed.The algorithm combines with the cross-layer idea which processes the TCP header in IP layer and uses dynamic list to increase certain connection-oriented function for the connectionless IP protocol.The CCFA can classify different flows characteristics and forward those flows to different available paths.NS2 simulations prove that the algorithm achieves a better bandwidth performance,a high link utilization and low delay with certain storage overhead,and it can be easily deployed into the programming routers of the next generation networks(NGN). |
