information technology and the continued convergence of their
services, technologies and business models. Within
telecommunications, the historic separations between fixed
networks, mobile telephone networks and data communications are
diminishing. Similarly, information technology and enterprise
communications show convergence with telecommunications. These
synergies are captured in the concept of Next Generation Networks
that result from evolution to new technologies, enabling new
services and applications.
Network Convergence creates a framework to aid the
understanding of Next Generation Networks, their potential for
supporting new and enhanced applications and their relationships
with legacy networks. The book identifies and explains the concepts
and principles underlying standards for networks, services and
applications.
Network Convergence:
* Gives comprehensive coverage of packet multimedia, enterprise
networks, third generation mobile communications, OSA/Parlay and
developments in fixed networks.
* Gives an integrated view of diverse information and
communications systems and technology through a common NGN
Framework.
* Delves into protocols, APIs and software processes for
supporting services and applications in advanced networks.
* Discusses a variety of applications of telecommunications
supporting IT and IT enhanced by communications.
* Follows developments in operations support systems standards
and links these to next generation networks.
* Includes a wealth of examples, use cases, tables and
illustrations that help reinforce the material for students and
practitioners.
* Features an accompanying website with PowerPoint presentations,
glossary, web references, tutorial problems, and 'learn more'
pages.
This essential reference guide will prove invaluable to advanced
undergraduate and graduate students, academics and researchers. It
will also be of interest to professionals working for
telecommunications network operators, equipment vendors, telecoms
regulators, and engineers who wish to further their knowledge of
next generation networks.
