STRUCTURE OF THE Part I describes single and multi-server queues. Part II treats single and multiclass queueing networks (MQNETs). Part III introduces asymptotic methods, including queueing networks in heavy traffic, large deviations, call centers, queues in space, and the supermarket model. Part IV outlines the use of optimization in queueing networks. Part V presents Markov chains and processes, Brownian motion, and weak convergence in the Appendix.
