Information Model: From Abstraction to Application

“…Therefore, we think it reasonable to present, as a first step, a much simpler model than those mentioned above. We follow the simplicity philosophy exemplified by the network modeling works in [7,15,16]. These works, however, did not consider the specific features of multimedia resources as described in section 2.2.…”

Today's enterprises are accepting networked systems as a fundamental part of their information technology strategy. The constant growth in quantity and quality of networked systems and the thereby arising problems concerning complexity, heterogeneity and diversity of components in a multi-vendor environment require a sophisticated management of resources. Increasingly the automation of such management is being demanded. In this paper we introduce an architecture for the integrated management of all resources in a networked system, i.e. application, system and network resources. The architecture uses domains as flexible and pragmatic means of grouping resources and of specifying management responsibility and authority boundaries. It maintains a clear distinction between management objectives and the resources being managed in order to provide an integrated view of the various tasks of management as well as an integrated and uniform view of the distributed and heterogeneous managed environment. The uniform management model on which the architecture is based is expressive enough to capture the full richness of management structures and policies both within enterprises and between them. It allows for recursive and generic structuring, we consider as the basis for management activity automation. As an example, we apply our architectural concepts to structure the management of a high speed multi-network (ATM, DQDB, FDDI). Emphasis lies on an automated Quality of Service management in the FDDI management domain.

In this paper, recently concluded work on the development of a communication support tool kit is reported. The analysis, design and implementation steps of this project follow closely the Open Distributed Processing reference model (RM-ODP). We have used the ODP concepts and design rules as the basis of our development. In this paper we present the results of ODP's application on a specific case along with all the additional elements resulting from our case analysis. . IntroductionIn this paper we present the research activity carried on at both TELECOM Paris and Doxa Informatique for the realization of the Doxa Distribution Tool Kit (DDTK). Our research has been done within the framework of a pilot project for a telecom operator. DDTK provides communication support for distributed applications. Using portable communication tools as well as data presentation tools based on standard application interfaces, DDTK supports applications within distributed and heterogeneous environments. It administrates these tools in order to manage the communication from one application to an other and reuse the called treatments. The global objectives are:• the provision of a client/server communication model supporting message exchanging through message queues, • the treatment of the heterogeneity of a distributed environment as well as the interoperability between the different sub-sets constituting the information system, • the securization of the system by considering the information distribution, the heterogeneity as well as the decentralisation of responsibilities, • The administration of the transport network, the telecommunications infrastructure as well as of applications. To cope with the complexity of distributed systems and to meet the applications requirements in terms of distribution, interworking, interoperability and portability we have followed the overall framework of ODP that provides us with design rules and guidance to meet the previously mentioned requirements. Following the five ODP viewpoints, we pass from the analysis, to the design and implementation ofDDTK.In this paper, considering the complexity of the subject, we focus our presentation on the development work concerning the DDTK communication module and its basic mechanism: the message queue. Following the five viewpoints' presentation order, we will present the K. Raymond et al. (eds.), Open Distributed Processing
