基于端到端数据的矩的网络时延估计算法
Algorithm for Network Delay Estimation Based on End-to-End Data Moment
摘要
Abstract
The up-to-date algorithms on delay tomography are based on the discrete delay mode, but it is low efficiency in this mode.This paper proposes a continuous delay mode, whose delay is distributed on a function with some parameters.According to the rule of multicast and based on end-to-end moments, the parameters can be estimated using nonlinear least squares and the best step is chosen by the one-dimension Newton search in iteration.Experimental results on Matlab and NS2 simulation show that the algorithm needs little storage and is simple with high efficiency.关键词
