Performance Analysis of Bulk Flow TCP for Routing in Optical Network

Abstract

Information through optical networks has been extensively studied in recent year to provide high through put, high capacity for the Internet traffic. Optical packet switching network deploying buffering, wavelength conversion and multipath routing could be the most suitable one. However due to the packet oriented routing and switching, network can result in a large amount of packet out-of-order, packet loss and cause various delays in arriving upon end system, causing TCP flows that comprise those packets corrupted. The corrupted flows can increase the business of the internet traffic and cause malfunction in the higher layer protocol. In this paper, a novel performance analysis for routing and switching in optical IP networks has been proposed and implemented. The effect of fixed and variable size in flow discard (FD) and early flow discard (EFD) process to achieve higher throughput rate has been studied extensively. We have achieved the loss is only about 24.95 % in optical flow routing which is 71.17 % in optical packet routing. This technique ensures a maximum and uniform delay in arrival of packet and it increases the throughput.
