            Abstract : 
In this letter, based on 2-D s-z domain stability analysis, we derive stability conditions under which the TCP/RED system is stable. According to the proposed conditions, we can present the network parameter p_{max}´s stability bounds that lead to stable operations of the TCP/RED system. The simulation results illustrate the validity of the stability conditions.
