WebAbstract: In datacenter networks, flows need to complete as quickly as possible because the flow completion time (FCT) directly impacts user experience, and thus revenue. Link failures can have a significant impact on short latency-sensitive flows because they increase their FCTs by several fold. Existing link failure management techniques cannot keep the … WebGearbox provides its simplicity and performance advantages by allowing slight discrepancies in packet departure time from strict WFQ. We show that Gearbox's normalized departure time discrepancy is bounded and has a negligible impact on bandwidth allocation and flow completion time (FCT). photo of zoom
