(Solved) : 9 Suppose Distribute File Size F 9 Gbits 6 Peers Server Upload Rate U 91 Mbps 6 Peers Uplo Q44144647 . . .

9) Suppose you distribute a file of a size of F = 9 gbits toeach of 6 peers. The server has an upload rate of u = 91 mbps andthe 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 theirdownload rates are d1 = 11 Mbps, d2 = 19 Mbps, d3 = 21 Mbps, d4 =31 Mbps, d5 = 17 Mbps, and d6 = 27 Mbps. What is the basis of thespecific minimum time?

a For this problem, the server download plus the maximum timefor peer download

b Download rate of Peer 1 – d1

c Download rate of Peer 5 – d5

d Server upload rate

e Upload rate of Peer 1 – u1
