Provides a bridge between math theory and the practical use of computers in the field of network performance analysis analytical tools of the topic are explored and supported by examples in j throughout comprehensive treatment of network calculus ? requiring only a background in mathematics the purpose of network performance analysis is to investigate how traffic-management mechanisms deployed in the network affect the allocation of resources amongst its users and the performance they experience. This topic can be studied by the construction of models of traffic management mechanisms and observing how they perform by applying them to some flow of network traffic. This useful volume introduces concepts and principles of network performance analysis by example, using the j programming language. J is rich in mathematical functionality, which makes it an ideal tool for analytical methods. The book favours a practical approach and develops functions in j to demonstrate mathematical concepts
