Abstract

Performance of existing TCP implementation are not satisfactory in Optical Burst Switched (OBS) networks. TCP throughput suffers in OBS networks due to undesired timer expiry as a result of burst loss in bufferless OBS networks. TCP misinterprets any loss as a signal for congestion and burst assembler introduces different delays to different TCP segments. In this paper we propose a loss differentiation scheme that includes the assembly time in the decision making process. We present a protocol level technique for estimating assembly time at the TCP end points and use this information to differentiate congestion induced loss or contention induced loss.
