A comparison of client-server and P2P file distribution delays In this problem, you'll compare the time needed to distribute a file that is initially located at a server to clients via either client-server download or peer-topeer download. The problem is to distribute a file of size F=10 Gbits to each of these 6 peers. Suppose the server has an upload rate of u=86Mbps, and that the 6 peers have upload rates of: u1=24Mbps,u2=21Mbps,u3=22Mbps,u4=25 Mbps, u5=21Mbps,u6=13Mbps, and download rates of: d1=37Mbps,d2=35Mbps,d3=30Mbps,d4=40 Mbps, d5=23Mbps,d6=12 Mbps, Answer the following questions: 1. What is the minimum time needed to distribute this file from the central server to the 6 peers using the client-server model? 2. What is the minimum time needed to distribute this file using peer-to-peer download
