What is the maximum time a station has to wait for media access. What type of applications care?
MaxTime = ~(#of stations * T_neg) (T_neg is the negotiated target token rotation time) Even at maximum load, this is unlikely. To get this worst case the ring basically must go from zero offered load to maximum offered load (all stations enqueueing ~T-neg of frames) virtually instantenously. If this doesn’t happen, the ~T_neg of available bandwidth is split between multiple stations with each fraction of the bandwidth being passed along the ring with each token rotation. This results in a given station having multiple transmit opportunities within MaxTime. To reduce MaxTime change the T_req of a station to some lower value (eg 8 msec). This is done through the MIB parameter fddiPATHMaxT-Req.
