11) Suppose you distribute a file of a size of F = 9 gbits to each of 6 peers. The server has an upload rate of u = 91 mbps and the 6 peers have upload rates of u1 = 13 Mbps, u2 = 26 Mbps, u3 = 29 Mbps, u4 = 18 Mbps, u5 = 12 Mbps, and u6 = 18 Mbps and their download rates are d1 = 11 Mbps, d2 = 19 Mbps, d3 = 21 Mbps, d4 = 31 Mbps, d5 = 17 Mbps, and d6 = 27 Mbps. What is the minimum time needed to distribute this file using peer-to peer?

a Peer 5 download time -d5

b The sum of server and peer upload rates

c Peer 1 upload time - u1

d Server upload rate

e Peer 1 download rate - d1
