Objective CASSIOPEIA has been running from 1992 through to 1994. Its mandate was to contribute to the discipline of Integrated Service Engineering by defining an Open Services Architectural Framework (OSA) suitable for rapid introduction of new and enhanced services and their management. - To specify OSA for a market context characterised by a wide variety of services, offered by many providers in co-operation and in competition.- To build consensus on OSA within the 'Intelligence in Services & Networks' Project Line- To disseminate OSA in major international forums.The research focuses on the definition and verification of the architecture for integrated service engineering (ISE) called OSA (open service architecture) for integrated broadband communications (IBC).Specific objectives of the research include:specification of OSA for a market context characterized by a wide variety of services, offered by many providers in cooperation and competition;building of a consensus on OSA;dissemination of OSA in major international forums.Four worlds of concern have been identified in IBC from the OSA perspective: a universe of IBC actors using, providing, and managing services; an open set of services, seen as distributed applications; a service support environment, seen as a logical infrastructure consisting of a network of cooperating systems; a resource infrastructure, seen as a universe of computing and telecommunications devices.OSA organizes the world of services by means of OSAAPP, an open services design architecture for applications, and the service support environment by means of OSASYS, an open services provision architecture for systems. The universe of actors and the resource infrastructure are not the focus of OSA, but provide environments that are represented in the framework.OSAAPP provides a canonical structuring of the problem domain of services, which can be used as taxonomy for a component library, and a specific component model, particularly suited to the unified design of usage and management aspects of services and to an environment of nested services (ie where chains of reuse relations between services are typical). OSASYS provides a service machine structure, reference interfaces, rules and system oriented components to guide configuration and deployment of services on an IBC target infrastructure.Technical Approach CASSIOPEIA, in an integrated approach to both service control and service management, has tackled the long term objectives of both IN and TMN. The ODP reference model has been used as a key input to handle the distributed processing aspects of the logical infrastructure supporting IBC: it has been adapted, where necessary, to support specialised IBC requirements. Key Issues - Integrated approach to service control and management.- IBC Service Models and service decomposition.- Service provisioning in an open telecommunications service market.- Applicability of ODP to the IBC environment. Expected Impact The definition of OSA has paved the way: - To a suitable framework for cost-effective design, provisioning and management of advanced telecommunications services.- To the adoption of international standards for Open Services Architectures.
