A. Supposed N packets arrive simultaneously to a link at which no packets are currently being transmitted or queued. Each packed is of length L and the link has a transmission rate R. What is the average queuing delay for the N packets?

B. Now supposed that N such packets arrive to the link every LN/R seconds. What is the average queuing delay of a packet?

C. What is the stability limit, i.e., how often can a batch of N packets arrive to ensure that the queue does not grow to infinity?
