Flow completion time fct
WebMar 25, 2024 · Short flows are latency/flow completion time (FCT) sensitive, and long flows are throughput sensitive. Short flows arrive in large numbers [ 15 ] and remain alive for a very small period of time, whereas long flows are very few but remain alive for a much longer period of time [ 12 , 13 , 14 ]. Web–Flow completion time (FCT): what the users care about • Heavy-tailed flow size distributions –Pareto distribution –Mice and elephants –Scheduling algorithms for exploiting them. 3 Unit step response vs FCT • Historically, congestion control research has considered the performance

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 … WebAbstract: Minimizing the flow completion time (FCT) is widely considered as an important optimization goal in designing data center networks. However, existing schemes either rely on the precondition that the size and deadline of each flow is known in advance, or require modifying the switch hardware, which is hard to implement in practice. In ...
WebApr 19, 2013 · L 2 DCT reduces the mean flow completion time by up to 50% over DCTCP and by up to 95% over TCP. In addition, it reduces the completion for 99th percentile flows by 37% over DCTCP. We present the design and analysis of L 2 DCT, evaluate its performance, and discuss an implementation built upon standard Linux protocol stack. WebApr 7, 2024 · As a result, the Timeout (RTO) mechanism is frequently triggered, leading to the expansion of the flow completion times (FCT) of such applications by orders of magnitude. Hence, we seek an alternative method that does not change the virtual machines and that can effectively expand the loss cycle duration to enable short flows to …
