Research on mathematical model of RED algorithm
Guangwei Bai · Jisuanji gongcheng yu sheji · 2008
RED algorithm detects incipient congestion by computing the average queue size,and avoids the congestion by controlling the average queue size,and avoids TCP global synchronization.First derive the equilibrium values of the TCP window size and the buffer occupancy of the RED gateway.The parameters of RED algorithm are sensitive about the environment of network.The mathe-matical model is set to present the performance and the algorithm of RED.The steady state behavior of the RED algorithm is analyzed by explicitly modeling the congestion control mechanism of TCP.Finally how control parameters of the RED algorithm should be con-figured for achieving better performance is discussed.
