Service quality and cost control are critical success factors for the communications industry and performance engineering is vital in achieving both. It enables service quality to be 'built in' to products; cost control is achieved by addressing potential problems at an early stage, before the costs to remedy problems rise and large failure costs are incurred.
Telecommunications Performance Engineering includes both introductory material, giving a comprehensive overview of the subject area, and in-depth case studies illustrating the latest tools and techniques. Performance engineering throughout the whole life-cycle is discussed, including modelling, measurement, testing and capacity management. In addition, the book covers cutting-edge information and technology on the designs used to protect the performance levels of overloaded networks. A wide range of system and network applications are covered, from broadband, IP networks, and intelligent networks providing telemarketing services to combined Web/telephony systems, operational support systems and call centres. This book is essential reading for communications managers, designers, performance engineers and students.
