Abstract | We present, pFabric, a minimalistic datacenter fabricdesign that provides near-optimal performance in termsof completion time for high-priority flows and overallnetwork utilization. pFabrics design eliminates nearlyall buffering on switches (switches have only 20KB ofbuffering per port), requires almost no congestion con-trol and uses only simple mechanisms at each switch.Specifically, switches are only required to locally andgreedily decide what packets to schedule and drop ac-cording to priorities in the packet header and do notmaintain any flow state or rate estimates. Rate-controlis almost unnecessary, all flows start at line-rate andonly slow down in the extreme case of congestion col-lapse. We show via simulations using realistic workloadsand topologies that this simple design achieves near op-timal flow completion times and network utilization. |
