The present wireless communication system is moving towards the IP enabled network, where the cellular services are integrated with IP network for the transmission of data. Such networks are generally termed as IP-RAN network. In this network the Transmission Control Protocol (TCP) is the most widely used method to achieve elastic sharing between end-to-end IP flows. At present the core network basically relies on end-system TCP to provide congestion control and sharing but this will not be acceptable in coming future because, to avoid time-out, each TCP connection requires few packets to be stored in the network, and most of that storage occurs in the router buffer which leads to congestion.
