We present, pFabric, a minimalistic datacenter fabric design that provides near-optimal performance in terms of completion time for high-priority flows and overall network utilization. pFabric's design eliminates nearly all buffering on switches (switches have only ~20KB of buffering per port), requires almost no congestion control and uses only simple mechanisms at each switch. Specifically, switches are only required to locally and greedily decide what packets to schedule and drop according… CONTINUE READING
