[Solved]Question 5 10p Consider Ethernet 100 Mbps Csma Cd Used 25km Local Area Network Coax Cables Q37269915

Question 5 (10p) Consider an Ethernet of 100 Mbps with CSMA/CDis used for 2.5km local area network over coax cables 2 · 108m/sec.The Ethernet frame format is shown below.

a) What is the minimum slot time for CSMA/CD in such anetwork?

b) What is the maximum frame time in such an Ethernet?

c) What is the estimated efficiency of the Ethernet when themaximum frame size is used?

d) After the 3rd collision in the Ethernet, what the averagenumber of backoff time wrt time slots?

e) Assume that the slot time is selected to be 51.2µsec. Ifthere are two nodes A and B at the two ends of in this network.Both of them start transmission at t =0. When (at what time) willthey detect collisions? Suppose KA = 0 (backoff time slot) and KB =1 (backoff time slot). At what time does B schedule itsre-transmission?
