ABSTRACT
One of the more interesting areas of mathematics that many readers experience every day is waiting line analysis, also commonly referred to as queuing theory. Every time we approach a toll plaza, enter a fast food restaurant, and walk to position ourselves into a line or line up in a bank for service, we are in a waiting line. Over the past 30 years, a considerable amount of mathematical research has been performed that resulted in the development of a series of queuing systems that can be used to model different types of waiting lines. Fortunately for network personnel, this effort can also be applied to a variety of communication systems. For example, consider the operation of remote bridges and routers.
