Experimental comparison of high-speed transmission control protocols on a traffic-driven labeled optical burst switching network test bed for grid applications

Abstract

It is well known that the classic transmission control protocol (TCP) Reno is inadequate to address the requirements of emerging grid applications on an optical burst switching (OBS) network. To find the most efficient TCP in the scenario of grid over OBS, in this paper, the implementation of a traffic-driven labeled OBS (LOBS) network test bed is presented and the performance of several prominent high-speed TCPs, including HSTCP, TCP Westwood, and FAST TCP, are experimentally compared over the test bed. A modified theoretical model for TCP Reno over OBS is investigated, which is more accurate in modeling TCP Reno throughput compared with previous works and can further verify the experimental results.
