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