This brand new title provides an insight into the rich diversity of techniques, tools and knowledge used in performance engineering, covering the whole life cycle - from design through to operation - of both networks and systems. Performance modelling is discussed as an essential technique, providing the ability to predict performance through a quantitative understanding of how varying demand affects the behavior of a system or network. Performance testing is analyzed, offering the final opportunity to address the concerns of economic pressures pushing the identification and resolution of performances further down the supplier chain.Also available:Mobile and Wireless Communications: Key Technologies and Future Applications - ISBN 0863413684Carrier Scale IP Networks: designing and operating Internet networks - ISBN 0852969821The Institution of Engineering and Technology is one of the world's leading professional societies for the engineering and technology community.
