    Abstract: Methods, systems, and computer readable media for testing time sensitive network (TSN) elements are disclosed. According to one method for testing a TSN element, the method occurs at a test system. The method includes synchronizing a test system clock with a clock at a system under test (SUT). The method also includes receiving a sequence of messages, wherein the sequence of messages is generated using schedule rules associated with a TSN stream. The method further includes determining, using timing information associated with the test system clock, whether the schedule rules are accurately implemented by the SUT.

    Abstract: Methods, systems, and computer readable media for testing and/or determining scheduling fidelity in a time sensitive network (TSN) are disclosed. According to one method for determining scheduling fidelity in a TSN, the method occurs in a test system. The method includes receiving, via a system under test (SUT), at least one expected receive time indicating when a test packet is expected to be received by at least one destination. The method further includes computing, using the at least one expected receive time and at least one actual receive time, a time variation metric associated with the test packet.

    Abstract: Methods, systems, and computer readable media for synchronizing timing among network interface cards in a network equipment test device are disclosed. One method includes generating and sending timing synchronization measurement signals to the management network interface card and a test network interface card in the network equipment test device. The method further includes recording times of receipt of the timing synchronization measurement signals at the management network interface card and the test network interface card. The method further includes adjusting timing of the test network interface card using the times of receipt of the timing synchronization measurement signals.
