1. A method of determining a link latency between stations on a network, comprising the steps of:

  • placing a physical layer of a remote station into a remote loopback configuration such that all data received from the network is transmitted back onto the network;

    transmitting a specified data pattern from a local station to the remote station;

    detecting at the local station the specified data pattern that has been transmitted back onto the network by the remote station; and

    determining the link latency between the local station and the remote station as a function of the time elapsed between the transmitting of the specified data pattern from the local station and the detecting of the specified data pattern at the local station.
