5. [3+3+2-8 pts] Consider distributing a file of F bits to N peers using a client-server architecture. Assume a fluid model where the server can simulaneously transmit to multiple peers, transmitting to each peer at different rates, as long as the combined rate does not exceed u a) Suppose that u Ndwi. Specify a distribution scheme that has a distribution time of NFlu b) Suppose that u,/N2dSpecify a distribution scheme that has a distribution time of Fd c) Show that the minimum distribution time is in general given by max INFuFlin
