Abstract
Designing scalable and cost-effective data center interconnect architectures based on electrical packet switches is challenging. To overcome this challenge, researchers have tried to harness the advantages of optics in data center environment. This has resulted in exploration of hybrid switching architectures that contains an optical circuit switch to serve long bursts of traffic along with an electrical packet switch serving short bursts of traffic. The performance of such hybrid switching architectures in data center is dependent on the schedulers. Building hybrid schedulers is challenging because of varying properties of data center traffic, increasing network demands, requirements imposed by hybrid network architecture etc. Slow schedulers can negatively impact the performance of the data center network because of poor resource utilization. With future demands, this problem is going to escalate motivating the need for faster schedulers. One approach to do this would be to use a hardware based scheduler. In this paper we propose a framework that can be used to explore and evaluate hardware based hybrid schedulers.
