Abstract: A system for providing test receive port resiliency includes a network equipment test device including a port module for transmitting test packets to and receiving packets from a device under test (DUT). The system further includes a port central processing unit (CPU) associated with the port module for processing packets that the CPU receives from the DUT. The system further includes a configurable pre-filter associated with the port module for pre-filtering the packets to prevent at least some of the packets from being forwarded to the port CPU. The system further includes a pre-filter rules generator for analyzing the packets forwarded to the port CPU and for automatically generating a pre-filtering rule to be used by the pre-filter for filtering subsequent packets received from the DUT.

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 microburst testing are disclosed. According to one method, the method includes defining a test that is divided into one or more test cycles, wherein each test cycle includes a plurality of time intervals for providing packets to destination ports of N ports of the network equipment test device via a plurality of ports of a network switch under test, wherein N is an integer. The method further includes initializing a replication count. The method also includes executing an instance of the test using the replication count. The method further includes monitoring packets switched by each port of the network switch under test to determine an indication of buffering capacity of each port of the network switch under test.
