Abstract

In this poster, we find that the congestion control algorithms which try to acquire close-to-zero queue would encounter bandwidth waste because there would be a RTT gap for other flows to take over after a flow finishes. By distinguishing the packets of the last round in a flow's lifespan, we can improve the bandwidth utilization of datacenter network. We modify the INT process in HPCC and the FCTs of long flows can be reduced by about 20%-30% from our ns3 simulation.
