Architecting the Telecommunication Evolution examines the driving force and fundamentals of the SOA, introducing a telecommunications-based SOA that enables cross-network services between the Internet and the telecommunications network. This book demonstrates how current telecommunications services can be accessed from Internet endpoints, but future networks will have to export discrete events to the Internet, leading to service execution. It discusses VoIP as a specialization of Web services and places it in the context of a telecommunications-based SOA. Providing comprehensive coverage, this text is ideal for researchers, students, and working professionals.
