Consider a router that uses fair queuing with two queues for flow$$f$1$and$$f$2$respectively$.$ If$$f$1$uses packets of length $1200,$ and$$f$2$uses packet of length $400,$ to what flows do the first five packets sent? Assume that the queues are always backlogged and that a router can transmit a packet from either one of the two flows at any point in time. Assume that the tie$-$breaks in finish time are broken arbitrarily.
