Converged networks, which combine voice, data, fax and video
transmissions into a cohesive networking infrastructure - all centered on the Internet
Protocol, or IP - promise a number of advantages over existing, separate networking
environments.
But to successfully design and implement a converged network requires
expertise on both the voice and data networking sides of the house. Unfortunately, few
individuals have these credentials - either you are a voice networking expert, and
familiar with circuit switching and connections between PBXs, or you are a data networking
expert, familiar with packet switching and connections between routers and servers.
The objective of this text is to bridge the gap between the voice and data networking
sides, and provide the reader with the opportunity to fill in their areas of weakness with
solid technical information. In addition, this text presents a number of case studies,
from architectural, financial and technical perspectives that illustrate real-world
applications for these technologies.
Our review
This book provides an easily readable introduction to Voice over
IP. It assumes little prior knowledge of the reader on the subject, and provides a
particularly good introduction to the Internet Protocol, before launching into the
specific details of transporting voice over IP.
A broad range of subject matter is
covered, although the sections on implementation and Quality of Service are a little
weak. Nevertheless, many sources of further research are offered.
Written in a clear and unassuming style, we recommend this book highly.
