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.
