Abstract: The parameter setting for Random Early Detection(RED) queue management algorithm depends on the user’s experience and its related theoretical guidance exists some defects at present. A comprehensive analytical method is proposed to set the RED parameters. Through adopting mathematical expectation method, steady-state behavior of discrete model of the TCP/RED congestion control mechanism is analysed, and the relationship between the network in the steady-state expectations and RED parameters are derived. Simulation results show that the method can provide an accurate and efficient method of RED parameter setting.
