Performance analysis of optical burst switching with fast optical switches for data center networks

In this paper, we evaluate the performance of methods of optical burst switching (OBS) designed for data center networks (DCNs) by using network-level simulation. We use fast optical switches in a single hop topology with a centralized optical control plane and OBS with a two-way reservation protocol that results in zero burst loss. We use different workloads with various burst assembly parameters to identify a suitable set of parameters. Our results show that, with suitable choices for the OBS system parameters, excellent delay performance with zero burst loss can be obtained, even in the presence of high load or high values of the topological degree of communication.
