1. A method for measuring network performance comprising the steps of:

  • dividing packets flowing through a first point into frames, the first point being any point in the network that supports a packet flow, said dividing step comprising;

    selecting a header associated with the packets flowing through the first point;

    associating the header with the packet flow;

    storing the header in a storage associated with the packet flow;

    incrementing a packet count; and

    detecting duplicate packets generated by network nodes;

    capturing information n about the packets in packages that correspond to the frames;

    correlating each package with packets flowing through a second point, the second point being any other point in the network that supports the packet flow; and

    calculating network performance information based on the correlated packages.
