A Modified Model for Efficient Explicit Congestion Reduction in High Traffic High Speed Networks Through Automated Rate Controlling

The conventional TCP suffers from poor performance on high bandwidth delay product links meant for supporting data transmission rates of multi Gigabits per seconds (Gbps). This is mainly due to the fact that during congestion, the TCP´s congestion control algorithm reduces the congestion window cwnd to frac12 and enters additive increase mode, which can be slow in taking advantage of large amounts of available bandwidth. In this paper we have presented a modified new model and to overcome the drawbacks of the TCP protocol and propose to carry out a study of the modified model based on various parameters viz., Throughput, fairness, stability, performance and bandwidth utilization for supporting data transmission across the high speed networks.
