摘要： There are disclosed methods and apparatus for testing a network. A plurality of packets may be transmitted over the network from one or more source port units. Each transmitted packet may include a packet group identifier (PGID) corresponding to a unique combination of values for a plurality of tracking factors. The packets may be received at one or more destination port units. Each destination port unit may extract the PGID from each received packet and may accumulate traffic statistics for each of the plurality of PGIDs. The accumulated traffic statistics for at least some of the plurality of PGIDs may be aggregated to report summary statistics for a selected tracking factor.

摘要： There are disclosed apparatus and methods for testing a network. An apparatus for testing a network may include first and second memory banks configured to alternate between being active and inactive in a complementary manner. A traffic receiver may receive traffic comprising a plurality of packets from the network, accumulate traffic statistics, store the accumulated traffic statistics in the active memory bank of the first and second memory banks, and copy contents of the first memory bank, when inactive, to a third memory bank, and copy contents of the second memory bank, when inactive, to a fourth memory bank. A port processor may aggregate at least selected traffic statistics stored in the third memory bank and the fourth memory bank.
