| Service-Oriented Design: The jABC Approach (2008) | |||||||||||||||
Abstract | |||||||||||||||
| Service-Oriented Design has driven the development of telecommunication infrastructure and applications, in particular the so-called Intelligent Network (IN) Services, since the early 90s: IN services are customized telephone services, like e.g., Free-Phone, where the receiver of the call can be billed if some conditions are met, Virtual Private Network, enabling groups of customers to define their own private net within the public net, or Credit Card Calling, where a number of services can be billed directly on a credit card account. The realization of new IN services was quite complex, error prone, and extremely costly until – a service-oriented, feature-based architecture, – a corresponding standardization of basic services and applications in real standards, and – adequate programming environments came up: they set the market, enabled the flexibilization of services, and dramatically reduced the time to market. Today the current trend moves toward triple-play services, which blend voice, video, and data on broadband wireline | |||||||||||||||
