摘要
在对二进制ABR流量控制算法建模的基础上,得出缓存队列长度与相关参数的关系。根据这种关系,经过比较分析,提出一种参数自适应算法,通过动态选择Nrm值,加快了网络对拥塞的响应速度。仿真表明,该算法在减轻振荡、快速解除拥塞以及减小对缓存的依赖方面有着良好的性能。
Based on modeling of binary algorithm of ABR flow control, the relationship between queue length and related parameters is deduced. According to this relationship, a new algorithm with adaptive parameter is proposed based on comparative analysis. Through setting Nrm dynamically, this algorithm speed up response to congestion. Simulation indicates this algorithm has good performance in alleviating oscillation, eliminating congestion fast and abating the dependence on cache.
