摘要： 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.

摘要： There are disclosed an apparatus, a machine readable media, and methods for testing a network. The apparatus may include a statistics engine coupled to a memory. The statistics engine may extract a packet group identifier (PGID) from a packet received from the network and retrieve traffic statistics associated with the PGID from the memory. The retrieved traffic statistics may include a packets-per-interval count and a packets-per-interval threshold, the packets-per-interval count indicating a number of packets received within a time interval of a sequence of time intervals. At the start of each new time interval, the statistics engine may set a flag indicating whether or not the packets-per-interval count for the previous time interval was equal to or greater than the packets-per-interval threshold. The flag may be saved in the memory as part of the traffic statistics associated with the extracted PGID.
