Poster: NegotiaToR: A Simple On-demand Reconfigurable Data Center Network

Optical switching technology has developed fast in recent years, which has the potential to provide high goodput as well as low latency in reconfigurahle data center networks (RDCN). However, existing optical RDCN proposals fail to balance goodput, latency, and design complexity well. In this paper, we introduce NegotiaToR, a simple optical RDCN architecture. NegotiaToR utilizes on-demand scheduling to ensure high performance and reduces possible deployment complexity with an in-band control protocol to do the schedule distributedly. Our preliminary evaluation shows that NegotiaToR outperforms the state-of-the-art optical RDCN proposal under similar complexity in both goodput and flow completion time (FCT).
