By Sanjay K. Bose (auth.)

Queueing is a side of recent existence that we stumble upon at each step in our day-by-day actions. even if it occurs on the checkout counter within the grocery store or in gaining access to the net, the fundamental phenomenon of queueing arises each time a shared facility should be accessed for carrier through a ]arge variety of jobs or shoppers. The learn of queueing is critical because it gravides either a theoretical history to the type of carrier that we could count on from any such facility and how within which the power itself will be designed to supply a few designated grade of carrier to its consumers. Our learn of queueing was once essentially encouraged by way of its use within the examine of communique platforms and computing device networks. a few of the desktops, routers and switches in this kind of community will be modelled as person queues. the total procedure may perhaps itself be modelled as a queueing community delivering the necessary carrier to the messages, packets or cells that have to be carried. program of queueing concept offers the theoretical framework for the layout and examine of such networks. the aim of this e-book is to aid a path on queueing platforms on the senior undergraduate or graduate Ievels. this type of path might then give you the theoretical historical past on which a next direction at the functionality modeHing and research of desktop networks could be based.

For a queue in equilibrium, the system performance parameters for this case may be found as follows. Mean number in system Average arrival rate to system Aeff = f Ak P k k~ = fl [1 - exp(- A )] Jl Using these and Littlc's result, we get the mean time W spent in system by a customer (including both the waiting time and the time to get service) as In this case, we can compute W directly as weil.

16 Chapter 2 Note that when the system is in state k this birth rate is the rate at which the system state can increase by one. e. the rate at which the system state can decrease by one in state k. In the queueing theory context, the birth rate would typically correspond to the rate of arrivals of new jobs or customers to the queue whereas the death rate would be the rate at which customers/jobs leave the queue after completion of service. e. state k. e.

In the following, we will first derive the distribution of Q and then use that to derive the distribution of W.
