基于参数估计的随机早期探测改进算法
, PP. 88-91
Keywords: 随机早期探测,队列管理,拥塞控制,互联网,传输控制协议
Abstract:
流量控制是互联网有效运行的必要条件.随机早期探测RED(RandomEarlyDetection)是一种基于整条链路的积极队列管理技术,它能显著地提高网络的利用率、稳定性和公平性,是IETF倡导使用的流量控制技术.它由Hashem首先提出雏型,Floyd对之作出了重大改进,形成了较为完善、实用的RED技术,为了在应用中增大RED的适应范围,Fang又提出基于参数自适应的RED.由于现有方法未能稳定、准确地刻画网络流量特征,在流量特性差异较大时,以上方法均难以有效控制网络流量.在本文中,作者首先给出了估计流量特性的解析方法,该方法较参数自适应具有更好的稳定性和准确性;并据此提出了一种RED改进算法,最后通过动态仿真,证明该改进算法提高了RED的适应性,降低了网络时延,减小了时延抖动.
