VHDL may sound like a new Internet language, but it really stands for VHSIC (Very High Speed Integrated Circuit) Hardware Definition Language. VHDL borrows ideas from software engineering (architectural, behavior, and formal models, as well as modular design) and is used to design today's custom integrated circuits, from cell phones to microwave ovens and even CPUs. Peter Ashenden's The Designer's Guide to VHDL shows you how to use this language to write a hardware design, which you can then test in a simulator before "synthesizing" it into an actual hardware design in silicon.

How well does your enterprise stand up against today's sophisticated security threats? With this book, security experts from Cisco Systems demonstrate how you can detect damaging security incidents on your global network -first by discovering which assets you need to monitor closely, then by helping you develop targeted
strategies and pragmatic techniques to identify security incidents.
Security Monitoring offers six steps to improve network monitoring, based on the authors' years of experience conducting incident response to keep Cisco's global network secure. These steps will guide you through the following:
- Develop Policies: define the rules, regulations, and criteria against which to monitor
- Know Your Network: build knowledge of your infrastructure with network telemetry
- Select Your Targets: define the subset of infrastructure where you'll focus monitoring
- Choose Event Sources: identify the event types needed to discover policy violations
- Feed and Tune: collect data and generate alerts, tuning systems using context
- Maintain Dependable Event Sources: prevent critical gaps in your event collection and monitoring
To help you understand this framework, Security Monitoring illustrates its recommendations using a fictional mobile telephony provider. Each chapter's approach and techniques are overlaid against this fictional example with diagrams and detailed examples.
These recommendations will help you select and deploy the best techniques for monitoring your own enterprise network.

Wireless LANs have become mainstream over the last few years. What started out as cable replacement for static desktops in indoor networks has been extended to fully mobile broadband applications involving moving vehicles, high-speed trains, and even airplanes. This book is designed to appeal to a broad audience with different levels of technical background and can be used in a variety of ways: as a first course on wireless LANs, as a graduate-level textbook, or simply as a professional reference guide. It describes the key practical considerations when deploying wireless LANs and equips the reader with a solid understanding of the emerging technologies. The book comprises 38 high-quality contributions from industry and academia and covers a broad range of important topics related to 802.11 networks, including quality of service, security, high throughput systems, mesh networking, 802.11/cellular interworking, coexistence, cognitive radio resource management, range and capacity evaluation, hardware and antenna design, hotspots, new applications, ultra-wideband, and public wireless broadband.

A comprehensive presentation of the video communication techniques and systems, this book examines 4G wireless systems which are set to revolutionise ubiquitous multimedia communication.4G Wireless Video Communications covers the fundamental theory and looks at systems’ descriptions with a focus on digital video. It addresses the key topics associated with multimedia communication on 4G networks, including advanced video coding standards, error resilience and error concealment techniques, as well as advanced content-analysis and adaptation techniques for video communications, cross-layer design and optimization frameworks and methods. It also provides a high-level overview of the digital video compression standard MPEG-4 AVC/H.264 that is expected to play a key role in 4G networks.

This book offers a comprehensive explanation on how to dimension, plan, and optimize WiMAX networks. The first part of the text introduces WiMAX networks architecture, physical layer, standard, protocols, security mechanisms, and highly related radio access technologies. It covers system framework, topology, capacity, mobility management, handoff management, congestion control, medium access control (MAC), scheduling, Quality of Service (QoS), and WiMAX mesh networks and security. Enabling easy understanding of key concepts and technologies, the second part presents practical examples and illustrative figures to explain planning techniques and optimization algorithms.

При создании н обслуживании любой сети возникает масса больших и малых проблем, о решении которых ничего не говорится в теоретических фолиантах. Оказывается, многие из них можно решить, примени совокупность нескольких технологий или внедряя некоторые технологии там. где они в соответствии со своей целевой функцией не могут быть использованы.
