A promising solution to increasing busty traffic over the Internet can be Optical Burst Switched (OBS) networks with scalable and efficient multicast support. The efficiency of multicasting in OBS networks depends on: the burstification process, the multicasting schemes, tree sharing strategies, construction of shared trees, multicast schemes for dynamic(More)
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.(More)
Performance of existing TCP implementations over Optical Burst Switched (OBS) networks is not satisfactory, as they suffer from false congestion detection. As the contention induced losses are more common than congestion induced losses in OBS, the TCP reduces the congestion window even when there is no congestion. This effect, in turn unnecessarily reduces(More)
