Contrary to popular belief, Ethernet switches are not inherently secure. Security vulnerabilities in Ethernet switches are multiple: from the switch implementation, to control plane protocols (Spanning Tree Protocol [STP], Cisco® Discovery Protocol [CDP], and so on) and data plane protocols, such as Address Routing Protocol (ARP) or Dynamic Host Configuration Protocol (DHCP). LAN Switch Security explains all the vulnerabilities in a network infrastructure related to Ethernet switches. Further, this book shows you how to configure a switch to prevent or to mitigate attacks based on those vulnerabilities. This book also includes a section on how to use an Ethernet switch to increase the security of a network and prevent future attacks.

Empowered by today’s high-performance computers interconnected over LANs and WANs, companies are faced with the daunting task of bringing workability to the diversity and complexity of today’s data communications landscape. This new, comprehensive resource addresses key network management challenges, showing you how to: tie together incompatible LANs, meld legacy systems and LANs, extend the reach of LANs with wireless links, protect information assets from various disaster scenarios, and consolidate multi-protocol traffic over a single WAN backbone in a way that guarantees appropriate service levels.
Moreover, this hands-on guide defines management system requirements for the enterprise, and identifies the tools and expertise companies need to manage systems and networks in wired and wireless environments. You will learn how to design and test networks before implementation, and harden systems and networks against internal and external attacks with effective security administration and the application of specific tools. Putting infrastructure issues into proper perspective, this book will help you succeed in managing advanced communications systems and networks.

WiMAX Broadband Wireless Access Technology, based on the IEEE 802.16 standard, is at the origin of great promises for many different markets covering fixed wireless Internet Access, Backhauling and Mobile cellular networks. WiMAX technology is designed for the transmission of multimedia services (voice, Internet, email, games and others) at high data rates (of the order of Mb/s per user). It is a very powerful but sometimes complicated technique.
The WiMAX System is described in thousands of pages of IEEE 802.16 standard and amendments documents and WiMAX Forum documents. WiMAX: Technology for Broadband Wireless Access provides a global picture of WiMAX and a large number of details that makes access to WiMAX documents much easier. All the aspects of WIMAX are covered. Illustrations and clear explanations for all the main procedures of WiMAX are pedagogically presented in a succession of relatively short chapters

To be competitive, service providers cannot customize every installation but must simultaneously offer services that meet a wide range of perceived customer needs. This guide shows commercial service providers and equipment vendors how to build competitive service offerings for enterprise-specific needs.
In general, the book is organized into three main parts. Chapters 1 through 5 deal with defining customer requirements and the abstract provider architecture. Chapters 6 through 8 deal with building and extending carrier facilities and transmission systems. Chapters 9 through 13 deal with the intelligent communications systems overlaid onto the physical structures, which to varying extents involve Internet Protocol (IP)–based control planes, and possibly IP forwarding.

Protocols and Architectures for Wireless Sensor Networks provides a thorough description of the most important issues and questions that have to be addressed in a wireless sensor network. Wireless sensor networks combine current research trends from a number of different disciplines – hardware design, information & signal processing, and communication networks to name but a few. This single resource makes the crucial aspects of these research fields accessible to the reader. The authors give an overview of the current state-of-the-art and put all the individual solutions into perspective with each other.
This singular text provides academic researchers, graduate students in computer science, computer engineering, and electrical engineering, as well as practitioners in industry and research engineers, with an understanding of the specific design challenges and solutions for wireless sensor networks.
