file F u2ld server Internet N-1 N-1 The problem is to distribute a file of size F 5 Gbits to each of these 9 peers. Suppose the server has an upload rate of u, 100 Mbps, and that the 9 peers have upload and download rates in bits per second as shown in the table below. ul is the upload speed for the 1st peer, and d1 is the download speed for the 1st peer. Thus, ul's upload speed is 15Mbps and its download speed is 40Mbps ul1.50E+07d14.00E +07 u3 3.00E+07d3 4.50E+07 u4 2.85E+07d45.00E +07 d5 4.60E+07 u61.60E+09 d65.30E+07 u7 1.50E+07 d7 4.90E +07 d8 3.50E+07 u91.70E+07d93.80E+07 u51.90E+07 file F u2ld server Internet N-1 N-1 The problem is to distribute a file of size F 5 Gbits to each of these 9 peers.
