A Study on a Congestion Control for TCP/IP Networks

One of the serious problems in interconnected networks is traffic congestion which is caused by the difference of transmission speed or workload between the high speed network and the lower speed network. This paper presents a congestion control scheme for interconnected networks and applies this scheme to the TCP/IP(Transmission Control Protocol/Internet Protocol) protocol suite. In the TCP/IP protocol, the source quench mechanism is used to control congestion, but this mechanism has many defects. For this reason, the proposed congestion control scheme is applied to the TCP/IP protocol to improve the performance. By the simulation, this paper evaluates the performance of the scheme and the results show that the proposed scheme is more stable in the overload condition.
