Consider a direct link with capacity 1 Mbps (1,000,000 bits per second) between two end points A and B. One of the parties, say A, wants to send a file of 5000 bits in one or more packet(s). Header size of a packet is 200 bits. What is the optimal value for the number of packets that maximizes the throughput of this file transmission? What is this maximum throughput value? Assume no processing and propagation delays. Explain and show your work.
