    What is the difference between the utilisation formulas for the go back n protocol and the idle-request protocol.

    In general I have seen U= frame time/ cycle time being used for the idle-rq and have also seen U=frame length/(frame length + 2x Round trip delay)
    Which one formula is valid for which protocol??
