In this paper, we assess the performance of for optical burst switching (OBS) designed for performance computing (HPC) and cloud computing center networks (DCNs) by using network-level simulation. We consider short-duration bursts using the faster technologies that are now available. The modeled switch architecture features fast optical switches in single-hop topology with a centralized, software-defined control plane. Instead of using OBS with traditional (i. e. , one-way reservation), we consider OBS with a-way reservation protocol that results in zero burst loss. model different workloads with various data rates by different edge-to-core network oversubscription ratios to investigate the performance of such designs usage patterns. Our results reveal that the proposed shows considerable improvement in terms of and packet loss ratio and comparable performance in terms of delay when compared to traditional of OBS
