    Business-oriented development of telecommunication services
    SINNOTT, RICHARD ; Kolberg, Mario (Association for Computing Machinery, 1998)
    The development of software for distributed systems, e.g. telecommunication services, is a complex activity. Numerous issues have to be resolved when developing such systems, examples of which are language/system heterogeneity and remoteness of components. Interface definition languages (IDLs) are used as the basis for addressing some of these issues. IDLs allow for the specification of the syntactic aspects of the interfaces of the components in the system to be made. Whilst lending itself to issues of heterogeneity and location transparency, dealing with IDL as the basis for system development is not without its problems. Two of the main problems with IDL are its lack of behaviour and its lack of abstraction. Thus designers should not be constrained to work within the syntactic notations used to implement their systems, nor should they be unaided in how they might better design their systems. In this paper we show how these issues are being addressed in the TOSCA project in its development of a service creation and validation environment.

    Experiences of modelling and using object-oriented telecommunication service frameworks in SDL
    Kolberg, Mario ; Sinnott, Richard O. ; Magill, Evan H. (Elsevier, 1999)
    This paper describes experiences in using SDL and its associated tools to create telecommunication services by producing and specialising object-oriented frameworks. The chosen approach recognises the need for the rapid creation of validated telecommunication services. It introduces two stages to service creation; firstly a software expert produces a service framework, and secondly a telecommunications ‘business consultant’ who specialises the framework by means of graphical tolls to rapidly produce services. Here we focus on the underlying technology required. In particular we highlight the advantages of SDL and tools as well as issues and problems incurred.
