A Note on Some Fundamental Parameters of Multiqueue Systems [Letter to the Editor]

In a previous paper, an approximate method was developed for treating ac lass of multiqueue problems.

These problems are of considerable interest in the design of communication systems with many terminals. The purpose of this note is to obtain expressions for some parameters often used to characterize such systems and to draw an important distinction between two different types of averages—a distinction which can lead to serious consequences if overlooked.
