摘要
针对传统拥塞控制对大带宽时延积网络的局限性,在当前主动拥塞控制策略不够灵活的基础上,提出了一种基于备份路由的主动拥塞控制算法。通过对备份路由的发现和维护、拥塞检测和拥塞控制过程的研究,探索了一种数据重定向算法的实现方法,提出了算法的改进策略和应继续研究的问题。通过在NS2下的仿真实验,验证了算法在提高网络吞吐量、降低丢包率、提高网络资源利用率等方面的优越性能。
This article aimed at the localization of the traditional congestion control in large bandwidth-delay product networks.Given the low nimble of the current active network congestion control algorithms,a new one based on backup routing was presented.Besides the backup routing search and maintenance method,the depiction of congestion detection and congestion control process of the algorithm were studied,a packets redirection arithmetic was discussed.Finally,other questions about this algorithm were proposed.The performance such as better throughput,lower drop probability and higher utility of the network resource were validated by NS2.
