Brent Stewart, Denise Donohue, Jay Swan
ISBN: 1-58705-327-6
As a final exam preparation tool, the four CCNP Quick Reference Sheets included in this value-priced bundle provide a concise review of all objectives on all four of the new CCNP exams (BSCI 642-901, BCMSN 642-812, ISCW 642-825, and ONT 642-845). These digital Short Cuts provide you with detailed, graphical-based information, highlighting only the key topics in cram-style format.
With these documents as your guide, you will review key concepts required to manage the routers and switches that form the network core, as well as edge applications that integrate voice, wireless, and security into the network. These fact-filled Quick Reference Sheets allow you to get all-important information at a glance, helping you to focus your study on areas of weakness and to enhance memory retention of essential exam concepts.

Deployments of voice over IP (VoIP) networks continue at a rapid pace. Voice gateways are an essential part of VoIP networks, handling the many tasks involved in translating between transmission formats and protocols and acting as the interface between an IP telephony network and the PSTN or PBX. Gatekeepers and IP-to-IP gateways help these networks scale. Gatekeepers provide call admission control, call routing, address resolution, and bandwidth management between H.323 endpoints including Cisco IOS® voice gateways and Cisco® Unified CallManager clusters. IP-to-IP gateways allow VoIP calls to traverse disparate IP networks.
Cisco Voice Gateways and Gatekeepers provides detailed solutions to real-world problems encountered when implementing a VoIP network. This practical guide helps you understand Cisco gateways and gatekeepers and configure them properly. Gateway selection, design issues, feature configuration, and security and high-availability issues are all covered in depth. The abundant examples, screen shots, configuration snips, and case studies make this a truly practical and useful guide for anyone interested in the proper implementation of gateways and gatekeepers in a VoIP network. Emphasis is placed on the accepted best practices and common issues encountered in real-world deployments.
Cisco Voice Gateways and Gatekeepers is divided into four parts. Part I provides an overview of an IP voice network. Part II is dedicated to voice gateways, including discussions of Media Gateway Control Protocol (MGCP); H.323; Session Initiation Protocol (SIP); voice circuit options; connecting to the PSTN, PBX, and IP WAN; dial plans; digit manipulation; route selection; class of restriction; Survivable Remote Site Telephony (SRST) and MGCP fallback; digital signal processor (DSP) resources; and Tool Command Languaue (Tcl) scripts and Voice XML (VXML). Part III addresses voice gatekeepers, including detailed deployment and configuration. Part IV is dedicated to IP-to-IP gateways.

The Art of Network Architecture
Business-Driven Design
The business-centered, business-driven guide to architecting and evolving networks
The Art of Network Architecture is the first book that places business needs and capabilities at the center of the process of architecting and evolving networks. Two leading enterprise network architects help you craft solutions that are fully aligned with business strategy, smoothly accommodate change, and maximize future flexibility.
Russ White and Denise Donohue guide network designers in asking and answering the crucial questions that lead to elegant, high-value solutions. Carefully blending business and technical concerns, they show how to optimize all network interactions involving flow, time, and people.
The authors review important links between business requirements and network design, helping you capture the information you need to design effectively. They introduce today’s most useful models and frameworks, fully addressing modularity, resilience, security, and management. Next, they drill down into network structure and topology, covering virtualization, overlays, modern routing choices, and highly complex network environments.
In the final section, the authors integrate all these ideas to consider four realistic design challenges: user mobility, cloud services, Software Defined Networking (SDN), and today’s radically new data center environments.
• Understand how your choices of technologies and design paradigms will impact your business
• Customize designs to improve workflows, support BYOD, and ensure business continuity
• Use modularity, simplicity, and network management to prepare for rapid change
• Build resilience by addressing human factors and redundancy
• Design for security, hardening networks without making them brittle
• Minimize network management pain, and maximize gain
• Compare topologies and their tradeoffs
• Consider the implications of network virtualization, and walk through an MPLS-based L3VPN example
• Choose routing protocols in the context of business and IT requirements
• Maximize mobility via ILNP, LISP, Mobile IP, host routing, MANET, and/or DDNS
• Learn about the challenges of removing and changing services hosted in cloud environments
• Understand the opportunities and risks presented by SDNs
• Effectively design data center control planes and topologies
