The reconciliation of socially responsible (TCP) with irresponsible (UDP) network flows is the goal, while the idea behind the solution is to maintain the existing congestion management mechanisms for the former and to use the mobile agent paradigm to monitor and control the later ones. The comprehensive solution has been termed as Combined Model for Congestion Control (CM4CC) and elaborated in several articles. As responsive protocol, TCP controls the sending rates whenever there is an appearance of congestion. If a problem with UDP occurs, the model that incorporates seven different types of mobile agents takes over the sending rates of unresponsive flows and tames them down. The reaction is based on the information collected by monitoring agents that trigger the creation of control agents. Three types of agents are always present in the network, while the rest are created on as needed basis. CM4CC has been verified through a number of different network configurations and scenarios using the Optimized Network Engineering Tool (OPNET) simulation environment. The results suggest an encouraging solution to the problem of coexistence of responsive and non-responsive flows. It is crucial to the stability and performance of Internet today, where so many different applications and services run simultaneously.
