Access Layer Optical Switch
Optical switching, as a future-proof solution to overcome the bandwidth bottleneck of electrical switches, has attracted the widespread attention to researchers. Relying on the flexible-access interconnects to the scalable storage and compute resources, data centers deliver critical communications connectivity among numerous servers to support the housed applications and services. To provide the high-speeds and long-distance communications, the data centers have turned to fiber interconnections. The topology of data center networks (DCNs) plays significant roles in determining the communication bandwidth. Optical Circuit Switching (OCS): OCS has three distinct steps: links set-up, data transmission and links tear-down.
