A thorough understanding of heat exchange within a system, or between that system and its surroundings, is essential to the efficient design of machines and thermodynamic processes. This book, Heat Transfer, comprehensively explains the three divisions of such energy transfer: conduction, radiation and convection. The book covers the latest techniques and developments in energy transfer, takes a new approach to the study of radiation, introduces actual turbulent convection methods for industrial use, explains the critical coupling between convection and radiation in semi-transparent media, and provides data (Part 5) and real-world applications (Part 6) for realistic modelling. As a core text for mainstream courses in the subject, this book will do much to enhance the study of heat transfer. It can be used on a wide range of courses in departments of mechanical, chemical, process, aeronautical and marine engineering and physics.

"This book embraces all of the fields that the VoIP professional needs to be aware of in a clear and organized way... I recommend this book to all VoIP engineers, analysts, and IT managers who really want to know what they are talking about on the net, enjoy!" -Jeff Pulver, founder of the VON (Voice On the Net) coalition, and the founder and president of pulver.com 
Internet Telephony is now one of the most important and fastest growing technologies on the Internet, providing a viable technical and economical alternative to current telecommunication networks. Network providers and major companies are thus investigating how this emerging technology can be implemented, and at what cost and savings, in their organizations. 
This book provides a comprehensive practical overview of the technology behind Internet Telephony, giving essential information to IT professionals who need to understand the background and explore the issues involved in migrating the existing telephony infrastructure to an IP based real time communication service. Assuming a working knowledge of IP and ISDN networking, it addresses the technical aspects of real-time applications over IP, with an in-depth coverage of voice and video applications and protocols. Drawing on their extensive research and practical development experience in VoIP from its earliest stages, the authors give you access to all the relevant standards and cutting-edge techniques in a single resource. 
IP Telephony is organized into three clearly structured sections, focusing on protocols, voice technology and networks with a step-by-step approach. The protocols section sets IP telephony in context and then covers H.323, SIP and MGCP in detail, examining in turn their pros and cons, and using examples of particular cases and scenarios. The voice technology section describes voice quality, including the ETSI TIPHON approach, and voice coding, with summary comments on the applicability to VoIP telephone gateways. The final section on networks addresses Quality of Service (QoS) issues, explores dimensioning a VoIP network, and introduces Multicast routing, including a perspective on security and MBONE applications. 
Features: *detailed, up-to-date coverage of voice and video applications and emerging protocol standards:H.323, SIP, MGCP *practical strategies on how to plan and dimension a VoIP network *key points to look for in choosing a VoIP product &amp; how to avoid common pitfalls in implementation *examples and illustrations of standards and techniques including feedback information on issues discussed at standards meetings *details of QoS issues, Intserv (RSVP), DiffServ, RTP, SDF, companion standards, multimedia coding standards and coding algorithms

IP (internet protocol) Telephony, enabled by softswitches, is going to usher in a new era in telecommunications. By putting voice and data over one IP network, operators can enjoy lower costs and create new, revenue-generating "multimedia" services. This valuable reference offers a comprehensive overview of the technology behind IP telephony and offers essential information to network engineers, designers and managers who need to understand the protocols and explore the issues involved in migrating the existing telephony infrastructure to an IP-based real time communication service. Drawing on extensive research and practical development experience in VoIP from its earliest stages, the authors give access to all the relevant standards and cutting-edge techniques in a single resource. IP Telephony: Deploying Voice-over-IP Protocols: <ul>
<li>Assumes a working knowledge of IP and networking and addresses the technical aspects of real-time communication over IP.</li> <li>Presents a high level overview of packet media transport technologies, covering all the major VoIP protocols – SIP, H323 and MGCP</li> <li>Details specific strategies to design services for public networks where endpoints cannot be trusted and can be behind firewalls.</li> <li>Explores the problems that may arise from incomplete protocol implementations, or architectures optimized for private networks which fail in a public environment.</li> </ul>
This amply illustrated, state-of-the art reference tool will be an invaluable resource for all those involved in the practical deployment of VoIP technology.

IP Telephony: Deploying Voice-over-IP Protocols

In 1999-2000, VoIP (Voice-over-IP) telephony was one of the most successful buzzwords of the telecom bubble era. However, in 2001-2003, VoIP faced a very tough reality check. Now, manufacturers and service providers are drawing on what they have learnt from past experience in order to prepare to participate in the next major challenge faced by the telecommunications industry. 
This book offers a comprehensive overview of the issues to solve in order to deploy global revenue-generating effective "multimedia" services. Drawing on extensive research and practical deployment experience in VoIP, the authors provide essential advice for those seeking to design and implement a post-bubble VoIP network. Beyond VoIP Protocols: Understanding Voice Technology and Networking Techniques for IP Telephony <ul>
<li>Introduces the basics of speech coding and voice quality</li> <li>Demonstrates how quality of service may be built into the network and deals with dimensioning aspects, e.g. multipoint communications and how to model call seizures.</li> <li>Explores the potential of multicast to turn an IP backbone into an optimized broadcast medium</li> <li>Includes amply illustrated, state-of-the-art practical advice for formulating a complete deployment strategy</li> </ul> A companion volume to "IP Telephony: Deploying VoIP Protocols", this book takes the reader a stage deeper into how to prepare the network and exploit VoIP technology to its full potential.
