Patent ID: 10608913

Abstract:
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.
