A method for testing network route convergence includes receiving input for specifying a route convergence threshold and a frame loss tolerance for a route convergence test. The route convergence test is initiated by transmitting data plane traffic addressed to at least one destination to a device under test (DUT). At least one route is advertised to the DUT. A first time instance when the at least one route is advertised to the DUT is recorded. Data plane traffic routed by the DUT is monitored. It is detected when data plane traffic for the at least one route reaches the route convergence threshold. In response to detecting that the data plane traffic reaches the route convergence threshold, a second time instance is recorded and a route convergence validation test phase is initiated. During the route convergence validation test phase, an indication of frame loss for the at least one route is determined and an indication of validity or invalidity of the route convergence test is generated based on a relationship between the indication of frame loss and the frame loss tolerance.

Methods, systems, and computer readable media for conducting and validating network route convergence testing

Methods, systems, and computer readable media for network diagnostics are disclosed. According to one method, the method occurs at a diagnostics controller implemented using at least one processor. The method includes configuring a plurality of diagnostics nodes to observe traffic behavior associated with a system under test (SUT). The method also includes observing, using the diagnostics nodes, traffic behavior associated with the SUT. The method further includes detecting, using the traffic behavior, a SUT issue. The method also includes identifying, using SUT topology information, a network node in the SUT associated with the SUT issue. The method further includes triggering one of the diagnostics nodes to obtain node related information from the network node, wherein the diagnostics node uses at least one communications protocol to poll the network node for the node related information. The method also includes diagnosing, using the node related information, the SUT issue.

Methods, systems, and computer readable media for packet classification previewing are disclosed. Packet classification previewing is performed by a reserved preview packet classifier and initiated by a user. According to one aspect, a method for packet classification previewing includes providing a preview packet classifier. User input is received to classify packets using the preview packet classifier. In response to the user input, classification of packets is initiated using the preview packet classifier. Preview packet classification results are generated and displayed to the user, providing feedback as to whether the classifier configuration is correct or not as the user changes the configuration dynamically.
