Zusatztext "Evolving from the current PSTN to Internet Telephony is not an easy task. ? The two authors [of this book] are uniquely qualified to explain how this evolution can be architected. ? Both authors have used their unique expertise to produce this very first book on the topic."-From the Foreword by Roch Glitho! Ph.D.! Editor-in-Chief! IEEE Communications Magazine! 2003-2005 Informationen zum Autor Vijay K. Gurbani, Xian-He Sun Klappentext Taking a standards-based approach to converged services! Architecting the Telecommunications Evolution lays a foundation for a service-oriented architecture in telecommunications. The authors begin by outlining the development of Internet telephony! focusing on how to use the respective benefits of the traditional public switched telephone network (PSTN) and the Internet to create and implement more value-added services. These two eminent specialists then examine services that originate in the Internet and take advantage of PSTN services followed by PSTN-originating services using the Internet. They conclude with a discussion on how this convergence creates smart spaces in the telecoms domain. Zusammenfassung Service-oriented architecture (SOA) uses services as baseline for developing architectures and applications, as networks are built specifically to satisfy service requirements. This book outlines the challenges of providing crossover services and architectures and protocols that enables convergence between circuit- and packet-switched networks.
