![]() Generalize Equation 1.2 in Section 1.4.3 for heterogeneous processing rates, transmission rates, and propagation delays. Using Little's formula, what is the average packet arrival rate, assuming there is no packet loss? P17. The link's transmission rate is 100 packets/sec. Suppose that on aver- age, the buffer contains 10 packets, and the average packet queuing delay is 10 msec. Let d denote the average total delay (i.e., the queuing delay plus the transmission delay experienced by a packet. Let a denote the rate of packets arriving at the link. Let N denote the average number of packets in the buffer plus the packet being transmitted. In this problem, you will use Little's formula, a famous formula from queuing theory. Consider a router buffer preceding an outbound link. ![]() Based on the formula for the total delay (i.e., the queuing delay plus the transmission delay) derived in the previous problem, derive a formula for the total delay in terms of a and μ. 15, Let a denote the rate of packets arriving at a link in packets/sec, and let μ denote the link's transmission rate in packets/sec. Plot the total delay as a function of L/R. Provide a formula for the total delay, that is, the queuing delay plus the transmission delay. Suppose that the queuing delay takes the form IUR (1-1) for I < 1. Let I denote traffic intensity: that is, / La/R. Consider the queuing delay in a router buffer. What is the average queuing delay of a packet? P14.
