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

A system for measuring a schedule update time of a time aware shaper device under test (DUT), the system comprising:

• an emulated time aware shaper centralized network configuration (CNC) node for configuring the DUT with configurations for blocking or allowing forwarding of traffic from a plurality of gates of the DUT;
• an emulated time aware shaper talker;
• an emulated time aware shaper listener;
• and
• a test controller,
• wherein the emulated time aware shaper CNC node configures the DUT with a first configuration for blocking traffic from at least one gate of the DUT and configures the emulated time aware shaper talker to start sending traffic to the emulated time aware shaper listener via the DUT, the emulated time aware shaper starts the sending of the traffic to the emulated time aware shaper listener via the DUT, and the emulated time aware shaper listener confirms blocking of traffic from the at least one gate of the DUT,
• wherein the emulated time aware shaper CNC node transmits a second configuration to the DUT, wherein the second configuration opens at least one gate of the DUT that was closed by the first configuration to allow traffic from the at least one gate, and wherein the emulated time aware shaper CNC node records a time T1 of transmission of the second configuration to the DUT,
• wherein the emulated time aware shaper listener detects traffic from the at least one gate opened by the second configuration, records a time T2 of receipt of the traffic at the emulated time aware shaper listener, and
• wherein the test controller calculates a response time of the DUT to the second configuration based on T1 and T2, wherein the DUT comprises a real time aware shaper bridge and wherein the response time comprises a measurement of a time for the real time aware shaper bridge to change a gate control list of the real time aware shaper bridge from the first configuration to the second configuration.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

• providing an emulated time aware shaper centralized network configuration (CNC) node, an emulated time aware shaper talker, and an emulated time aware shaper listener;
• configuring a time aware shaper device under test (DUT) with a first configuration that blocks traffic from at least one gate of the DUT;
• transmitting traffic from the emulated time aware shaper talker the emulated time aware shaper listener via the DUT;
• confirming blocking of the traffic from the at least one gate of the DUT;
• transmitting, from the emulated CNC node to the DUT, a second configuration, where the second configuration opens at least one gate of the DUT that was closed by the first configuration to allow traffic from the at least one gate;
• recording a time T1 of transmission of the second configuration to the DUT;
• detecting traffic from the at least one gate opened by the second configuration at the emulated time aware shaper listener;
• recording a time T2 of receipt of the traffic at the emulated time aware shaper listener;
• and
• calculating a response time of the DUT to the second configuration based on T1 and T2, wherein the DUT comprises a real time aware shaper bridge and wherein the response time comprises a measurement of a time for the real time aware shaper bridge to change a gate control list of the real time aware shaper bridge from the first configuration to the second configuration.
