Methods, systems, and computer readable media for testing scheduling fidelity in a time sensitive network

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.
