As shown in our test results, Flent (which implements the RRUL test) is = indeed now capable of tracking the latency experienced by individual TCP = flows. It does not do so at the packet level, but at the socket level. Of course it is also possible to capture the traffic and analyse the = traces offline, if you really do want packet-level detail. - Jonathan Morton
