(6 marks) c. Consider the scenario in the diagram below, two hosts A and B are connected via four hops of links between them. The transmission rates of the links are 10 Mbps, 20Mbps, 40Mbps, and 80 Mbps as shown. The physical length of cach hope of the link is 200km. Assume that the propagation speed over the link is 2x 108 m/s. Currently we are continuously sending packets of size 40Mbits from host A to host B. 10 Mbps 20 Mbps 40 Mbps 80 Mbps Host A Router Router Router Host B 200 km 200 km 200 km 200 km i. Calculate the propagation delay from A to B of a single packet. (3 marks) ii. Calculate the transmission delay from A to B of a single packet. (3 marks) iii. Determine the maximum achievable from A to B. (3 marks) Total (25 marks)
