Abstract

RDMA technology gradually being used in the network to solve the performance problems caused by frequent read and write memory during transmission. The industry has used a lossless network environment with flow control to ensure that the technology is rigorous. In order to improve the network efficiency, congestion control is used to provide the largest possible transmission bandwidth. At present, DCQCN, TIMELY, HPCC and other solutions are used in the mainstream. This thesis improves the congestion control scheme of DCQCN. By adding the delay as the auxiliary judgment reference, aiming at the conflict problem of a large number of burst flows encountered by the current DCQCN mechanism under severe congestion, the change of round-trip delay is used as the judgment standard to improve the bandwidth utilization of the network.
