Question: 2.Suppose we use a stop-and-wait flow control in following situations, calculate its link utilization: 1) Satellite transmission. its propagation delay is 270 ms , data

2.Suppose we use a stop-and-wait flow control in following situations, calculate its link utilization:

1)Satellite transmission. its propagation delay is 270 ms , data rate is 32 Mbps, and typical frame size is 4000 bits.

2)LAN. Assume the max distance is 1 km,data rate is 10 Mbps, V=2108m/s and frame size is 500 bits.

3)Using a modem to transmit data over a telephone line. Assume the max distance is 100 km,data rate is 56 kbps, V=2108m/s and frame size is 500 bits.
