------please show the plots it is very necessary
!!!!!!!!!!!!!!!!!!
- Problem 2 (20 points): It is required to design a communication link running from Dammam to Jaddah. The link parameters are as follows: - Distance, d = 1500 km with a propagation delay of 5 micro seconds per km - The frame size, F, is equal to 5000 bits - Sliding window protocol with W = 4. The link bit rate Rb/s is to be determined/designed. a) (5 points) Plot the link utilization as a function of the link transmission rate R. Identify the transmission bit rate R* where the link utilization is less than 100% for rates greater than R*. b) (5 points) Plot the link throughput in frames per second.
