Methods, systems, and computer readable media for measuring schedule update time for a time aware shaper implementation

Abstract:

A method for measuring a schedule update time of a time aware shaper DUT includes configuring the DUT with a first configuration that blocks traffic from at least one gate of the DUT. The method further includes transmitting traffic from an emulated talker to an emulated listener via the DUT. The method further includes confirming blocking of the traffic from the at least one gate of the DUT and transmitting a second configuration from an emulated CNC node to the DUT, where the second configuration opens the at least one gate of the DUT, recording a time T1 of transmission of the second configuration to the DUT, detecting traffic from the at least one gate of the DUT at the listener, recording a time T2 of receipt of the traffic at the listener, and calculating a response time of the DUT to the second configuration based on T1 and T2.
