The definitive guide to planning, architecting, deploying, supporting, and creating Voice over Wireless LAN solutions. 

Recent advances make it possible to deliver high-quality voice and video communications over a wireless LAN (WLAN), replacing costly wired telephone and video surveillance systems and dramatically reducing support costs. However, today’s new voice over WLAN (VoWLAN) technologies require fundamentally different skills and techniques from those used in traditional voice and video systems. Now, there’s a complete guide to every facet of VoWLAN deployment: planning, design, installation, security, maintenance, and troubleshooting.

• Understand VoWLAN components, applications, and benefits
• See VoWLAN at work in actual enterprise environments
• Master VoWLAN signaling, including voice signal characteristics, A/D conversion, and compression
• Discover the latest 802.11 VoWLAN standards, including 802.11e, 802.11r, and 802.11k
• Secure IP-based VoWLAN systems against intrusion and compromise
• Analyze your organization’s requirements and design an optimal VoWLAN solution
• Plan for capacity, roaming, and integration with cellular systems
• Install, configure, test, verify, and validate your VoWLAN system
• Plan for operational support and implement appropriate administration tools and methods

Learn the basics of Cisco Express Forwarding (CEF) and gain advanced configuration, maintenance and troubleshooting skills through examples Learn the fundamentals of Cisco Express Forwarding (CEF) Study configuration models and real-world examples that you can use in your own networks Practice troubleshooting scenarios and management exercise to gain a deeper understanding of CEF How does a router switch a packet? What is the difference between routing a packet and switching a packet? What is this CEF feature that is referred to in Cisco documentation and commonly found in Cisco IOS commands? "Cisco Express Forwarding" addresses these questions through comprehensive discussions of Cisco Express Forwarding (CEF). CEF is a term used to describe one of the mechanisms used by Cisco IOS routers and Cisco Catalyst switches to forward packets. CEF offers the benefits of improved performance, scalability, and resilience. CEF is found in almost all Cisco IOS routers and Catalyst switches, however documentation of the topic is very scarce. This book addresses common misconceptions about CEF and packet switching across various platforms.  It will help you  understand CEF and how to troubleshoot whether there is a CEF or another problem occurring in the network. The book guides  you through CEF basics, supplying exercises and troubleshooting scenarios that enhance their ability to recognize common mistakes, as well as to provide them with some models for configurations that they can follow in their own networks.

The definitive guide to collecting usage information from Cisco networks

Understanding network performance and effectiveness is now crucial to business success. To ensure user satisfaction, both service providers and enterprise IT teams must provide service-level agreements (SLA) to the users of their networks–and then consistently deliver on those commitments. Now, two of the Cisco® leading network performance and accounting experts bring together all the knowledge network professionals need to do so. 

Network Management: Accounting and Performance Strategies imparts a deep understanding of Cisco IOS® embedded management for monitoring and optimizing performance, together with proven best strategies for both accounting and performance management.

• Compare accounting methods and choose the best approach for you
• Apply network performance best practices to your network
• Leverage built-in Cisco IOS network management system components to quantify performance
• Uncover trends in performance statistics to help avoid service degradation before it occurs
• Identify under use of network paths, so you can improve overall network efficiency
• Walk through hands-on case studies that address monitoring, capacity planning, billing, security, and voice networks
• Understand Cisco network performance, deliver on your SLAs, and improve accounting and billing

To become a Cisco Certified Network Associate (CCNA), you must learn the hundreds of IOS commands used by Cisco routers and switches. This handy reference from Cisco networking authority Todd Lammle is just what you need to master those commands. From a thorough introduction to Cisco’s basic operating system to making the transition to IPv6, Todd Lammle walks you through hundreds of commands with short, to-the-point explanations and plenty of figures and real-world examples.
