A Demonstration of Ultra-Low-Latency Data Center Optical Circuit Switching

by Nathan Farrington, George Porter, Pang-chen Sun, Alex Forencich, Joseph Ford, Yeshaiahu Fainman, George Papen, Amin Vahdat
"... We designed and constructed a 24×24-port optical circuit switch (OCS) prototype with a programming time of 68.5 µs, a switching time of 2.8 µs, and a receiver electronics initialization time of 8.7 µs [1]. We demonstrate the operation of this prototype switch in a data center testbed under various w ..."

Just-In-Time Signaling for WDM Optical Burst Switching Networks

by John Y. Wei, Ray I. McFarland, Jr. - Journal of Lightwave Technology , 2000
"... We describe the architecture, design, and implementation of a novel just-in-time (JIT) signaling protocol for optical burst switching (OBS) in wavelength division multiplexed (WDM) optical networks. The JIT-OBS paradigm is designed for ultra-low-latency unidirectional transport of data-bursts across ..."

c-Through: Part-time optics in data centers

by Guohui Wang, David G. Andersen, Michael Kaminsky, Konstantina Papagiannaki, T. S. Eugene Ng, Michael Kozuch, Michael Ryan , 2010
"... Data-intensive applications that operate on large volumes of data have motivated a fresh look at the design of data center networks. The first wave of proposals focused on designing pure packetswitched networks that provide full bisection bandwidth. However, these proposals significantly increase ne ..."

switching technology could benefit a data center network. In particular, we propose a hybrid packet and circuit switched data center network architecture (or HyPaC for short) which augments the traditional hierarchy of packet switches with a high speed, low complexity, rack-to-rack optical circuit-switched

Demonstration of End-to-End Bit-Parallel Memory Transactions Across the Ultra-Low Latency Data Vortex Optical Packet Switch

Integrating Microsecond Circuit Switching into the Data Center

by George Porter, Richard Strong, Nathan Farrington, Alex Forencich, Pang Chen-sun, Tajana Rosing, Yeshaiahu Fainman, George Papen, Amin Vahdat
"... Recent proposals have employed optical circuit switching (OCS) to reduce the cost of data center networks. However, the relatively slow switching times (10–100 ms) assumed by these approaches, and the accompanying latencies of their control planes, has limited its use to only the largest data center ..."
