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 = 5 ms, tp = 3 ms, N = 15 is:

1. 0.545
2. 0.655
3. 0.9375
4. 0.961

Asnwer: D

(tx)/(tx +(tp/N)) = (5)/(5+3/15) = 5/5.2 = .961

In a token ring network the transmission speed is 10$^7$ bps and the propagation speed is 200 meters/$\mu$s. The 1-bit delay in this network is equivalent to: 500 meters of cable. 200 meters of cable. 20 meters of cable. 50 meters of cable.
