Modern IP network services provide for the simultaneous digital transmission of data, voice and video. These services require congestion control algorithms and protocols which can solve the packet loss parameter can be kept under control. Congestion control is therefore, the cornerstone of the packet switching networks. It should prevent congestion collapse, provide fairness to competing flows and optimize transport performance indexes such as throughput, loss and delay. In this paper, the authors propose a congestion control mechanism with application to packet loss in networks with P2P traffic is proposed. In this new method the edge and the core routers will write a measure of the quality of service guaranteed by the router by writing a digital number in the option field of the datagram of the network packet.
