Hunting mice with microsecond circuit switches

Nathan Farrington, George Porter, Yeshaiahu Fainman, George Papen, Amin Vahdat
2012 Proceedings of the 11th ACM Workshop on Hot Topics in Networks - HotNets-XI  
In other words, we don't just hunt elephants, we also hunt mice. Traffic matrix scheduling rapidly time-shares circuits across many destinations at microsecond time scales.  ...  We briefly describe a working implementation of traffic matrix scheduling using a custom-built data center optical circuit switch with a 2.8 microsecond switching time.  ...  It is only with microsecond time-scale circuit switches that TMS becomes possible.  ...
