Consider a router buffer preceding an outbound link. in this problem, you will use little’s formula, a famous formula from queuing theory. let n denote the average number of packets in the buffer plus the packet being transmitted. let a denote the rate of packets arriving at the link. let d denote the average total delay (i. e., the queuing delay plus the transmission delay) experienced by a packet. little’s formula is n = a · d. suppose that on average, the buffer contains 10 packets, and the average packet queuing delay is 10 msec. the link’s transmission rate is 100 packets/sec. using little’s formula, what is the average packet arrival rate, assuming there is no packet loss?
