ExpressPass: Credit-scheduled delay-bounded congestion control in datacenters   In datacenters, when many hosts communicate simultaneously, large queueing delay dominates end-to-end latency. A novel technology, ExpressPass, is developed which bounds the network queue and thus achieves ultra-low end-to-end latency using credit packets. ExpressPass may replace existing datacenter congestion control without har...
