RESEARCH ON ENHANCING THE PERFORMANCE OF DATA SWITCHED NETWORKS USING THE KNOCKOUT PRINCIPLES AND PARALLEL FABRICS

Subject Area: Electrical Engineering

The accomplishment of high demand of data via the internet transmission medium when fabrics Data are of higher demand during peak hours, has led to packet retransmission. This research carries out the throughout performance of data switched network under study and developed data switch model that can reduce the packet loss by utilizing knockout principle and parallel fabrics. The knockout principle states that the likelihood of a packet being dropped due to contention can be made arbitrarily small with sufficiently large R number of packets and furthermore, for a given loss probability requirement, there exists on R number of packets that is independent of the switch size N such that the actual loss probability is not larger than the requirement. MATLAB simulation was carried out to show how the proposed technique can improve the performance of the data switched network in terms of throughout. The simulation result shows that the improvement achieve when knockout switch and routing fabrics was simulated on the data switched network is 35:027 bytes /sec as compared to the existing channel grouping technique.
