Abstract
A method for analyzing data center congestion control includes capturing packets traversing network switches in a data center configured with data center quantized congestion notification (DCQCN) parameters to regulate congestion in the data center. The method further includes generating, from the captured packets, a congestion notification packet (CNP) profile for the data center and a visualization of real traffic rates in the data center. The method further includes configuring a DCQCN performance predictor with the DCQCN parameters and providing the CNP profile as input to the DCQCN performance predictor. The method further includes simulating, by the DCQCN performance predictor, congestion control of the data center and generating, as output, a visualization of simulated ideal traffic rates in the data center given the CNP profile and the DCQCN parameters.
