An efficient congestion control methodology to enhance performance of TCP in wired network

The tremendous growth of internet demands effective congestion control mechanism to be converted into successful. The most of the internet traffic is based on TCP which guarantees End-to-end transmission. TCP compact with congestion with AIMD and packet conservation principal at plinth, slow start in highly congested scenario, fast Retransmission and fast recovery for multiple packets lost within same window. This paper is discussed about the modification to TCP's NewReno with multiple packet failure in the absence of SACK option. We observe that refinement of TCP NewReno reactive algorithm enhances the performance with change in congestion window to delve with all lost packet. This paper presents the methodology which enhances performance of the TCP's popular algorithm: TCP's NewReno. The methodology projected is implemented in NS2 (Network Simulator version 2) and compared ENewReno [11] and TCP NewReno. The simulation results show that proposed methodology enhances throughput as performance and packet loss.
