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 bandwidth-delay 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.
