Congestion is a major problem which really degrades network performance. Its effect on the delay is quite high which decrease the throughput in considerable amount. In this paper we have proposed a new congestion scheme which will enhance performance of network transmission by considering delay and throughput as main components. For this we are using Adaptive Explicit Congestion Notification method which allows us to control the network transmission from source to a receiver in a hierarchical manner by alterations in the receiving sending capacity. To achieve predictable average delays with adaptive explicit congestion notification would require constant tuning of the parameters to adjust to current traffic conditions. The sending and receiving ends are tuned according to its capacity and current network traffic condition once ECN (Explicit congestion notification) notification packet comes into action. The aim of this paper is to solve the parameter tuning problem of the AECN by dynamically setting up the network parameters to overcome delay in network transmission and hence to increase throughput .We will be comparing the performance of the ECN enabled system with the AECN enabled system. For this we are going to use JAVA , JNETPCAP and WINPCAP API’s by which we can create TCP packets, alter the fields of headers, send and receive packets etc.
