【Abstract】 A congestion control model called Early Random Congestion Control Model(ERCCM)is proposed based on the analysis of Random Early Detection(RED) and the comparison of basic congestion control method in Transfer Control Protocol/Internet Protocol (TCP/IP) and Connection Oriented Transfer Protocol/Connectionless Network Protocol (COTP/CLNP).It is suitable for all kinds of networks with absolute threshold congestion control.A method called Random Early Marking (REM) is also presented for use in Aeronautical Telecommunication Network (ATN) based on the principle of ERCCM and RED.The REM simulation results show that it can apparently overcome the defect of the absolute threshold marking methods in ATN and improve the performance of the network.更多还原
