Consider distributing a file of F bits to N peers using a client-server architecture. Assume a fluid model where the server can simultaneously transmit to multiple peers, transmitting to each peer at different rates, di, as long as the combined rate does not exceed u. For the case u/N dmin, specify a distribution scheme that has a distribution time of NF/u. For the case u/N dmin, specify a distribution scheme that has a distribution time of F/ dmin. Now argue that the minimum distribution time is in general max{ NF/u, F/ dmin }.
