Question: 1. Frames of 2000 bits are sent over a 2-Mbps channel using a geostationary satellite whose one way propagation time from earth is 250 sec.

1. Frames of 2000 bits are sent over a 2-Mbps channel using a geostationary satellite whose one way propagation time from earth is 250 sec. Ack's transmission time is negligible. Three-bit sequence numbers are used to represent frame numbers

A. What is the link utilization (channel efficiency) for Stop-and-wait?

B. What is the maximum achievable link utilization? Hints: Use max window size for three-bit frame number.

Note: you must consider round trip propagation time, which is twice the one-way time
