Alternative Switching Technologies: Optical Circuit Switches
Optical circuit switching is promising despite slow switching time : "Only a few ToRs are hot and most their traffic goes to a few other ToRs."

Slides from the "On the Feasibility of Completely Wireless Datacenters" at the ACM/IEEE Symposium on Architectures for Networking and Communications Systems (ANCS), October 2012. At their simplest, they operate as on/off gates, allowing light to pass with low insertion loss in the open state and blocking transmission (causing high insertion loss) when closed. One of the most critical technologies enabling the capacity expansion of fiber optic systems is Dense Wavelength Division Multiplexing (DWDM), which can exponentially increase the bandwidth of a fiber optic strand. Telecom transmissions, whether voice or data, have always been multiplexed in some.
