Queueing theory is an effective tool for studying several performance parameters of computer systems. It is a difficult subject, and the best way to comprehend queueing theory is by working on information processing problems. This manual contains all of the problems from Kleinrock's Queueing Systems, Volume 1 and their solutions. A summary heads each chapter and the solutions immediately follow the problems. The self-contained, user-friendly format makes this an ideal independent text or self-study text.
