Wireless OFDM Systems: How to Make Them Work?

IP is the protocol of choice in most corporate networks today. As those networks grow larger and their operation becomes vital for the enterprise, there is a strong need to design.or redesign them in a manner that will allow for their expansion while simultaneously maintaining smooth and stable operation. CCIE Professional Development: Advanced.IP Network Design presents the principles of good IP network design and is focused on planning corporate networks from the routing point of view. Choice of transport technologies, dimensioning of the network links, choice of routers, and routing problems specific to carrier networks are outside the scope of this book, The hook is targeted at network enpineers seeking solutions to grow and stabilize their networks. A general knowledge of IP networking and routing is required for understanding the presented material. It is, however, possible to gain basic understanding of routing protocols operation from the appendices. The book consists of four parts. Part One (Chapters 1 4 ) deals with network design principles, Part Two (Chapters 5-7) deals with interior routing, and Part Three (Chapters 8 and 9) deals with exterior routing. Part Four contains appendices. A consistent example network is used throughout this book to illustrate different design choices. Also, each chapter contains case studies, which either serve as a design example or present problems that may arise in particular circumstances. Each chapter ends with a summary and review questions. Chapter 1 introduces the main network design goal, which is stability, and discusses fadtbrs that affect stability in real networks. The authors suggest a threelayer network topology, consisting of core, distribution, and access layers, and present the design goals for each layer. Chapter 2 begins with general information necessary for understanding the IP address summarization followed by a discussion of the effect of summarizing at different places in the network. The remaining part of Chapter 2 deals with addressing. Four different address allocation strategies are discussed, allowing the reader to choose the most appropri.ate strategy depending on needs. Two case studies end Chapter 2. The first one deals with the problems that arise when a default route is set to an interBOOK REVIEWS/EDITED BY ANDRZEJ JAISZCZYK U I
