Abstract
It has been shown that burst retranmsission scheme and burst deflection scheme can effectively reduce the burst loss probability, thereby improving the performance of loss-based TCP implementations. However, both schemes introduce additional delays for bursts that are retransmitted or deflected. The additional delays could result in delay-based TCP falsely detecting network congestion, which may negatively impact the performance of delay-based TCP implementations, such as TCP Vegas. In this paper we investigate the delay-based TCP Vegas behavior over OBS networks. Furthermore, we analyze the throughput of TCP Vegas over a barebone OBS network and an OBS network with burst retransmission.
