Develop cost-effective, long-term solutions for packetized voice

Analysts agree that within the next decade virtually all telecommunications traffic will travel over packet networks. Should your packetized voice be delivered over Layer 2 networks such as ATM or Frame Relay, or over Layer 3 IP networks?

Drawing upon years of practical experience with voice over data implementations, the authors of this book consider the advantages and disadvantages of IP versus traditional packet networks. The book explores the unique engineering problems posed by running voice over a connectionless network. And it supplies guidelines to help you decide when (or whether) to invest, and how to choose the best technologies for your organization. With the help of several case studies, the authors provide in-depth coverage of:
* Network architectures to support voice over IP
* Performance and voice quality considerations
* Compression and integration methods for IP transmissions
* Support protocols, including MPOA, RSVP, and RTP
* Voice-over-IP technology for intranets, routed networks, and the Internet
* The latest enabling technologies, such as voice characteristics, compression standards, and QoS
* Internet telephony servers and other support hardware

Review:

Daniel and Emma Minoli--the authors of Delivering Voice over IP Networks--have written a book that begins by discussing all the issues involved in IP-based voice systems. The book discusses the IP protocol, Resource Reservation Setup Protocol (RSVP), Asynchronous Transfer Mode (ATM), and packet voice communication. Since many factors can influence the quality of voice data transmission, there are several mathematical models that can be used to evaluate such transmissions. The authors introduce and explain each model, weighing the pros and cons. Chapter 5 covers the technology and standards (G.728, G.729, G.729A, and G.723.1) for low-bit rate vocoding. The last two chapters focus explicitly on IP voice communications and the Internet.

Ideally suited for programmers, the highly technical nature of this book makes it appropriate for serious students of voice technology. Those in the computer field who need to know not just what technology is available, but also the inner workings of voice technology, will enjoy Delivering Voice over IP Networks. --Rob Frankland

From the Publisher:

Internet-based telephony is an exciting prospect for every company running a TCP/IP stack network. But is won't be simple to deploy. Unlike traditional packet networks, IP networks are connectionless and pose entirely different engineering challenges. This book explores the potential investment in terms of both money and technology. It provides a review of important IP support protocols, detailed descriptions of voice-over-IP technologies, and case studies of Internet telephony servers.
