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.
