Book: QoS Measurement and Evaluation of Telecommunications Quality of Service
ISBN: 9780471499572
Publisher: John Wiley & Sons
Year: 2001
Most people know that quality of service (QoS) in telecommunications has
grown in importance over the past decade. This is thanks to the new competitive
environment which has followed as a direct result of privatization and
de-regulation, forcing companies to increase the quality of their networks and
services. Yet QoS means different things to different people. In some developing
countries where it is a struggle for QoS managers to wrestle with outdated
equipment, even making a network perform in the way it was designed
is an improvement in QoS.
The Quality of Service Development Group (QSDG) is a field trial group of
QoS professionals from over 130 carriers, service providers, research companies
and vendors from around the world. While informal, we operate under the
auspices of Study Group 2 of the ITU-T. We gather annually in different
geographic regions to discuss QoS issues within our companies. QSDG Magazine
(www.qsdg.com) which as well as being our group’s official magazine, is
also the only periodical in the world about QoS, and is distributed in 201
countries and territories.
William C. ‘‘Chris’’ Hardy is unquestionably among the leading lights in the
field of QoS. As chairman of the QSDG I appreciate the contributions Chris
has made, both to the QSDG group as a whole, and through his QDSG Magazine
column Telecom Tips and Quality Quandaries, on which much of this
book is based. If you are coming to grips with QoS in your company, this is the
place to start.
