Abrégé

Transmissions in a data center communications network are monitored at a sending computer, the transmission of data packets being controlled by control messages sent by a receiving computer. The monitor at the sending computer measures the time that a burst of data takes to be transmitted from the sending computer to the receiving computer. Based on feedback received from the receiving computer, the monitor at the sending computer calculates one of more estimated completion times for the transmission. The estimated completion times will approximately match the measured completion time if the network is not the bottleneck for communication. When there is a mismatch between the estimated and measured completion times, this is logged and the information is used to trigger analysis to detect the reason and possible causes for the network under-performing.
