Suppose N packets arrive simultaneously to a link in which no packets are currently being transmitted or queued. Each packet is of length L and the link has transmission rate R.

a) What is the average queueing delay for the N packets?

b) For each problem parameter, how can modify it (increase/decrease/uncorrelated) in order to decrease the average queueing time?

c) What is the maximum rate at which the link can transmit packets if it doesnt have a queue (i.e. without discarding any)?
