Abstract: A method and system for measuring a convergence time of a network. Test traffic including a plurality of packet groups may be transmitted and received via the network. The network may be instructed to redirect packets belonging to a selected packet group from a first port of the network to a second port of the network. A first test port unit coupled to the first port may determine an arrival rate for the selected packet group and store a below threshold timestamp when the arrival rate first falls below a predetermined threshold rate. A second test port unit coupled to the second port may determine an arrival rate for the selected packet group and store an above threshold timestamp when the arrival rate first equals or exceeds the predetermined threshold rate. The convergence time may be determined based on the below threshold timestamp and the above threshold timestamp.
