3. Consider distributing a file of F bits held on a server to N peers using a P2P architecture. Let us denote the upload rate of the server, and let ui (di) denote the upload (download) rate of peer i. Assume a fluid model where the server can simultaneously transmit to multiple peers, transmitting to each peer at different rates, as long as the combined rate does not exceed us. Ignore propagation delav. Specify a distribution scheme to distribute the file in (approximately) time Flus and relations among the parameters for this time to hold. The relations among parameters should state that certain parameters or combinations of parameters are greater than or less than others. (Hint: consider breaking the file into chunks.)
