* Explores the architecture and data flow through a typical switch, including an analysis of switch fabric options
This book teaches the architectures, design principles, and troubleshooting techniques of a LAN, imparted via the presentation of a broad scope of data and computer communication standards, real-world inter-networking techniques, architectures, hardware, software, protocols, technologies and services as they relate to the design, implementation and troubleshooting of such a network.
The second edition of this information-packed, fully-illustrated handbook features the new developments in software services for LANs as well as ongoing research and improvements in the technologies.
Today's enterprise cannot effectively function without a network, and today's enterprise network is almost always based on LAN technology. In a few short years, LANs have become an essential element of today's business environment. This time in the spotlight, while well deserved, has not come without a price. Businesses now insist that LANs deliver vast and ever-increasing quantities of business-critical information and that they do it efficiently, flawlessly, without fail, and most of all, securely. Today's network managers must consistently deliver this level of performance, and must do so while keeping up with ever changing, ever increasing demands without missing a beat. At the same time, today's IT managers must deliver business-critical information systems in an environment that has undergone radical paradigm shifts in such widely varied fields as computer architecture, operating systems, application development, and security. The Local Area Networks Handbook focuses on this collective environment, in which networking and information technology work together to create LAN-based enterprise networks. Topics have been selected and organized with this in mind, providing both depth and breadth of coverage. The handbook will provide you not only an understanding of how LANs work and how to go about selecting and implementing LAN products, but also of how to leverage LAN capabilities for the benefit of your enterprise.

A complete resource for assessing, auditing, analyzing, and evaluating any network environment With "Network Consultants Handbook, you will Learn from network audit and evaluation guidelines that aid in data gathering and analysis of network environments Work with tables and calculations that help provide near-real-time answers to internetworking issues and challenges Learn network diagramming tips that aid consultants and engineers in preparing consistent drawings for in-house documentation Discover how specific internetworking technologies fit into a design to create a networking solution for your customer Network consultants and engineers in today's industry continually face the challenge of assessing, auditing, and reviewing existing networks. Documenting, reviewing, and analyzing these changes in a customer's network is more challenging today than in the past, partly because of the explosive growth of converged applications and the Internet. Consultants and engineers often reinvent the wheel to gather and analyze relevant network information, particularly when examining a client's network while having little or no background information. "Network Consultants Handbook is a complete resource for assessing, auditing, analyzing, and evaluating any network environment. Intended for anyone who designs, manages, sells, administrates, or desires to understand various internetworking technologies, "Network Consultants Handbook demonstrates where and how to gather relevant information and how to analyze and document this information. Technology overviews peel away each layer of the network to provide a complete assessment. This book prepares you with form templates to completeduring a network audit, necessary device commands to aid in obtaining necessary information, and consistent forms to aid in documentation. Networks are like snowflakes: No two are alike. This is the challenge that network consultants, engineers, managers, designers, and anyone else involved with networks must face every day. Network Consultants Handbook provides the resources you need to evaluate and design networks, either as a desktop reference resource or in the field where the tables and calculations help provide near-real-time answers to internetworking issues and challenges. Companion Web Site The companion Web site for the book contains fully downloadable versions of the data gathering and analysis templates. These templates offer an easy-to-complete solution to gathering the data you need to complete your analysis of network environments. This book is part of the Cisco Press Networking Technologies Series, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.
As the demand for higher bandwidth has lead to the development of increasingly complex wireless technologies, an understanding of both wireless networking technologies and radio frequency (RF) principles is essential for implementing high performance and cost effective wireless networks.Wireless Networking Technology clearly explains the latest wireless technologies, covering all scales of wireless networking from personal (PAN) through local area (LAN) to metropolitan (MAN). Building on a comprehensive review of the underlying technologies, this practical guide contains 'how to' implementation information, including a case study that looks at the specific requirements for a voice over wireless LAN application. This invaluable resource will give engineers and managers all the necessary knowledge to design, implement and operate high performance wireless networks.· Explore in detail wireless networking technologies and understand the concepts behind RF propagation.· Gain the knowledge and skills required to install, use and troubleshoot wireless networks.· Learn how to address the problems involved in implementing a wireless network, including the impact of signal propagation on operating range, equipment inter-operability problems and many more.· Maximise the efficiency and security of your wireless network.
Here is the handbook with all the essential; nuts-and-bolts details network managers need to know; but won't find in any textbook. --
IT professionals who want to move into the networking side in a corporate or enterprise setting will find the detailed content they need to get up to speed on the very latest networking technologies; plus, current networking professionals will find this a valuable and up-to-date resource. This hands-on guide is designed so that you can select, design, and implement an actual network using the tutorials and steps in the book. Coverage includes an overview of networking technologies, including the hardware, software, transmission media, and data transfer processes; in-depth coverage of OSI and TCP/IP reference models; operating systems and other systems software used in today?s networks; LANs, WANS, and MANs, including the components and standards that operate within each type of area network; and more.
A hands-on guide to planning, designing, installing and configuring wireless LANs that prepares students for the Certified Wireless Network Administrator (CWNA) certification. This second edition offers in-depth coverage of wireless networks with extensive step-by-step coverage of IEEE 802.11b/a/g/pre-n implementation, design, security, and troubleshooting. Material is reinforced with hands-on projects at the end of each chapter from two of the principal wireless LAN vendors, Cisco and Linksys, giving the flexibility for this course to be taught in either a classroom or as an online course.
