Abstract: In the future Internet congestion control protocols, several groups of users may deploy different source algorithms in order to meet the different QoS requirements. The analysis of resource competition for congestion control systans with mixed deployement AIMD algorithm and MIMD algorthm was systematically studied, including the system model, the system steady-state analysis, the system stability analysis. In the end of this paper, simulations based on NS2 system validitied the analysis results of proposed method, and the resource competition between AIMD and MIMD algorithms.
