Deploying Voice over Wireless LANs

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

Cisco Catalyst(R) QoS: Quality of Service in Campus Networks (Networking Technology)

End-to-end QoS deployment techniques for Cisco Catalyst series switches

• Examine various QoS components, including congestion management, congestion avoidance, shaping, policing/admission control, signaling, link efficiency mechanisms, and classification and marking
• Map specified class of service (CoS) values to various queues and maintain CoS values through the use of 802.1q tagging on the Cisco Catalyst 2900XL, 3500XL and Catalyst 4000 and 2948G/2980G CatOS Family of Switches
• Learn about classification and rewrite capabilities and queue scheduling on the Cisco Catalyst 5000
• Implement ACLs, ACPs, ACEs, and low-latency queuing on the Cisco Catalyst 2950 and 3550 Family of Switches
• Understand classification, policying, and scheduling capabilities of the Catalyst 4000 and 4500 IOS Family of Switches
• Configure QoS in both Hybrid and Native mode on the Catalyst 6500 Family of Switches
• Utilize Layer 3 QoS to classify varying levels of service with the Catalyst 6500 MSFC and Flexwan
• Understand how to apply QoS in campus network designs by examining end-to-end case studies

Quality of service (QoS) is the set of techniques designed to manage network resources. QoS refers to the capability of a network to provide better service to selected network traffic over various LAN and WAN technologies. The primary goal of QoS is to provide flow priority, including dedicated bandwidth, controlled jitter and latency (required by some interactive and delay-sensitive traffic), and improved loss characteristics.

While QoS has become an essential technology for those organizations rolling out a new generation of network applications such as real-time voice communications and high-quality video delivery, most of the literature available on this foundation technology for current and future business applications focuses on IP QoS. Equally important is the application of QoS in the campus LAN environment, which is primarily responsible for delivering traffic to the desktop.

CBT Nuggets Cisco CCVP - Exam-Pack: 642-432 CVOICE

This training provides the core knowledge of Voice over IP (VoIP) required for implementing and supporting data and voice integration solutions at the network level. It helps you grasp the VoIP vision, and to answer three major questions most companies have about VoIP solutions:

• Why are so many companies moving to VoIP?
  
• What are the benefits of using VoIP?
  
• Is VoIP right for our company?

Once the CVOICE videos help you answer these three questions, they get into the nitty-gritty of VoIP implementation. They teach you how to move an existing PBX or Key System based network to the newer VoIP technology without getting rid of all your old equipment, so you can maximize the cost efficiency of your VoIP implementation. They teach you how to deploy a worldwide VoIP infrastructure, even using lower-end equipment. The videos also cover techniques that allow you to configure your Cisco router to continually monitor the WAN line quality and dynamically change connections as necessary.

"CVOICE [Exam-Pack: 642-432 from CBT Nuggets] not only prepares you for the Cisco exam, but also has multiple practical VoIP deployment videos showing exactly how an administrator would set this up in the real world," explained instructor Jeremy Cioara.

The videos cover all objectives for the Cisco CVOICE exam 642-432, which is required for CCVP, Cisco IP Telephony Express Specialist and Cisco IP Telephony Support Specialist certifications. A thorough understanding of Cisco networking such as CCNA or equivalent knowledge is recommended before viewing these videos. The training contains 19 videos providing more than 11 hours of instruction.
