This book is about wireless local area networks (WLANs) based upon the IEEE 802.11 standards. It has three primary objectives: * To introduce the principles of 802.11 wireless networks and show how to con- ure equipment in order to implement various network solutions. * To provide an understandingof the security implicationsof wireless networks and demonstrate how vulnerabilities can be mitigated. * To introduce the underlying 802.11 protocols and build mathematical models in order to analyse performance in a WLAN environment. The book is aimed at industry professionals as well as undergraduate and gra- ate level students. It is intended as a companion for a university course on wireless networking. A practical approach is adopted in this book; examples are provided throughout, supported by detailed instructions. We cover a number of wireless vendors; namely, Cisco's Aironet, Alactel-Lucent's Omniaccess and Meru Networks. While separate vendors, all three systems have a Cisco IOS-like command-line interface. The GNU/Linux operating system is used extensively throughout this book.

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, thereby enabling readers to explore the underlying principles behind network performance analysis. In addition, this allows the subject to become more accessible to those who, although have a mathematical background, are not pure mathematicians.

Topics and features:

a [ Uses an example-driven approach to introduce the fundamentals of network performance analysis

a [ Provides a concise introduction to the J programming language

a [ Presents network calculus as a method for designing and engineering networks

a [ Focuses on statistical analysis and stochastic processes

a [ Demonstrates how to simulate traffic with both short-range and long-range dependence properties

a [ Covers ATM QoS, and examines Internet congestion control

Network Performance Analysis will equally appeal to network professionals and postgraduates studying the topic by providing valuable analytical tools and using J as a means of offering a practical treatment of the subject. Dr. Holthas a broad range of industry experience and now regularly lectures on this topic.

This book brings Network Calculus closer to the network professional and will also have real appeal for postgraduates studying network performance. It provides valuable analytical tools and uses J as a means of providing a practical treatment of the subject. It builds a bridge between mathematics theory and the practical use of computers in the field of network performance analysis.
