“…TCP is very sensitive to the packet/burst losses and this has been shown in empirical study of different TCP implementations in OBS [34]. The authors in [32] presented 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. The authors in [37] introduce a new layer between TCP and OBS layers for burst retransmission to mitigate the effect of burst loss due to contention on TCP performance.…”

“…In order to overcome issues of TCP over OBS, several techniques have been presented in literature [26][27][28][29][30][31][32][33][34][35][36][37]. The authors in [26] evaluated the impact of burst assembly algorithms on different TCP implementations such as TCP Reno, New-Reno and SACK in OBS network and in other work [27], they proposed TCP implementation for OBS network called Burst TCP which tries to detect false time out and reacts properly.…”

In this paper, we consider the performance of TCP when used in data centre networks (DCNs) featuring optical burst switching (OBS) using two-way reservation. The two-way reservation is not suitable in wide-area OBS networks due to high bandwidthdelay product (BDP). The burst loss using traditional methods of one-way reservation can be mistakenly interpreted by the TCP layer as congestion instead of contention in OBS network, leading to serious degradation of the TCP performance. The reduced BDP in DCNs allows the use of two-way reservation that results in zero burst loss. The modelled architecture features fast optical switches in a single hop topology. We apply different workloads with various burst assembly parameters to evaluate the performance of TCP. Our results show significant improvement in TCP performance as compared to traditional methods of OBS as well as to a conventional electronic packet switching DCN.
