You need to compare the time needed to distribute a file to clients via either client- server download or peer-to-peer download. The file is initially located at a server. The problem is to distribute a file of size F = 40 Gbits to each of these 6 peers. Suppose the server has an upload rate of u = 33 Mbps, and that the 6 peers have upload rates of: U = 22 Mbps, U = 14 Mbps, u3 = 20 Mbps, u4 = 30 Mbps, us = 11 Mbps, u6 = 28 Mbps and download rates of: d = 30 Mbps, d = 22 Mbps, d3 = 27 Mbps, d4 = 28 Mbps, ds = 13 Mbps, de = 11 Mbps Answer the following questions and show all the computation steps clearly: a. What is the minimum time needed to distribute this file from the central server to the 6 peers using the client-server model? b. What is the minimum time needed to distribute this file using peer-to-peer download?
