An Introduction to Queues and Queueing Theory. Study and Evaluation Techniques for Queueing Systems, Telecommunication and Computational Model Systems. Little’s Law. Basic Queueing Theory - I (Analysis of M/M/-/- Type Queues), Basic Queueing Theory - II (Departures, Method of Stages, Batch Arrivals), Birth-Death Processes. Analysis of the simple M/M/1 and M/G/1 Queue. M/M/1/N Queues and Multi-Server Systems : M/M/m, M/M/m/K, M/M/m/m (Erlang – B). Applications and Simulation to Packet Scheduling in High-Speed Networks and Modern Wireless Networks.

Learning Results:
