Consider the queuing delay in a router buffer preceding an outbound

Consider the queuing delay in a router buffer preceding an outbound link with transmission rate R bps. Suppose N packets, each of length L, arrive at the buffer every LN/R seconds. What is the traffic intensity of the arriving packets? What is the average queuing delay of a packet? Comment why do network engineers always aim at operating networks at levels that are well below their capacity
