GATE | Gate IT 2007 | Question 72
  • Last Updated : 04 May, 2016

Consider a token ring topology with N stations (numbered 1 to N) 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. Ring latency is tp, while the transmission time of a frame is tt. All other latencies can be neglected.

The maximum utilization of the token ring when tt =3 ms, tp = 5 ms, N = 10 is
(A) 0.545
(B) 0.6
(C) 0.857
(D) 0.961


Answer: (C)

Explanation: Maximum efficiency of token ring = (tt)/(tt +( tp/n))
tt= 3 ms
tp =5 ms and n=10,
efficiency = 3/(3+.5)= .857
