BEYOND VOIP PROTOCOLS
Ouvrage 9780470023624 : BEYOND VOIP PROTOCOLS
IP telephony, enabled by softswitches, is going to usher in a new
telecom era. By putting voice and data over one IP network, operators
can enjoy lower costs and create new, revenue-generating `multimedia'
services. What are the advantages of IP Telephony? New entrants to the
communications service provider sector must provide data services as
well as voice. VoIP dispenses with the need to build two separate
networks. Offering a bundled package of services over one network means
greater efficiency and higher margins. With broadband fixed and mobile
access becoming more prevalent, service providers can offer a whole host
of telephony, data and internet services down the one connection.
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 the technology to its full potential. It first introduces the
basics of speech coding and voice quality. The authors go on to
demonstrate how quality of service may be built into the network and
deal with network dimensioning aspects such as multipoint communications
and how to model call seizures. A final section on multimedia encoding
and transport techniques such as multicast make this book an ideal
reference for engineers seeking to build communications networks for the
future.
* Detailed and thorough reference on the theory of speech coding and
voice quality and how that affects the services that can be provided.
* Covers quality of service issues and suggests appropriate
solutions
* Discusses network dimensioning, the challenges and the benefits.

This is THE "must have" book for all Engineers deploying VoIP in Carrier
and Operator companies and Internet Service providers.
The extensive coverage also makes this highly relevant for professional
network engineers, designers and managers, decision makers and project
managers overseeing VoIP implementations and market analysts and
consultants.
