consider a token ring topology with N stations , running token ring protocol where the stations are equally spaced .when a station gets the token it is allowed to send one frame of fixed size .

1) the max utilization of the ring if the transmission delay is 5ms and propogation delay is 3ms and N=15

as the processing is done at each station, hence total processing delay is 15*3=45, hence max utilization is 45/(45+3),

but the answer is wrong , the text book says its 0.545...can any one solve >?
