3. (a) (5 points) suppose n packets arrive simultaneously to a link at which no packets are currently being transmitted or queued. each packet is of length l and the link has transmission rate r. what is the average queuing delay for the n packets? (b) (5 points) now suppose that one of such n packets arrives to the link every l/2r seconds. what is the average queuing delay of a packet?
