Q. Calculate Utilization percentage of the link?

- System: Stop and wait ARQ

- Bandwidth: 1Mbps

- Round trip for one bit: 20ms

- Frame length: 1000 bits

Utilization percentage of the link =?

Solution

Bandwidth - delay product = 1 * 106 * 20 * 10 -3 = 20, 000 bits

Thus the sender can send 20000 bits before it receives the ack.

However the system is stop and waits. Therefore only one frame (1000 bits) is sent at a time.

Thus the link utilization = 20000 / 1000 = 5%
