    In this article we propose workflow techniques such as FUNSOFT for the specification of ODP Enterprise Models. Workflow-orientation as one of the most popular management paradigms and object-orientation as the state of the art software development paradigm are integrated in the ODP framework. Our example is related to our experience in the air traffic control application domain and will demonstrat... View full abstract»

    A network management system (NMS) has been built using distributed object technology and a four-layered architecture with device model objects. This NetKeeper NMS, which is built on a distributed object platform, has improved scalability and fault tolerance, and can be customized easily. It can thus be used to manage enterprise networks, which consist of a huge number of multi-vendor network devic... View full abstract»

    A new framework is required for the consistent and coordinated construction and configuration of multimedia components across heterogeneous distributed object environments. The paper presents a distributed multimedia component architecture which extends beyond the current well developed distributed object models, such as the Common Object Request Broker Architecture (CORBA) and the Microsoft Distr...

    Enterprise roles define the duties and responsibilities of the individuals which are assigned to them. This paper introduces a framework for the management of large distributed systems which makes use of the concepts developed in role theory. Our concept of a role groups the specifications of management policies which define the rights and duties corresponding to that role. Individuals may then be... View full abstract»

    Much of today's software development involves reengineering legacy applications, but the bulk of research and tools address new software development. The Distributed Object Management Integration System (DOMIS, 1993-96) project investigated how legacy applications can be incrementally modified, or migrated, by using distributed object management (DOM) technology. The paper describes a methodology ... View full abstract»

    The telephone network could be called the world's first distributed object computer system. The high reliability, availability and capacity requirements of the telephone network have forced the telecommunications industry to solve a number of key challenges. This paper discusses the applicability of these solutions to other areas of distributed object computing using the concept of “design p... View full abstract»

  • Mobility support: a multi-domain bridging matter

    We view mobility support as a bridging matter between fixed and mobile domains. In single domain systems, mobility is implicitly supported by access and location transparencies provided by the distributed processing environment (DPE). Distributed telecommunication systems span, however, several domains that are controlled by different actors and may also be fixed or mobile. Mobility is no longer a... View full abstract»

    The paper reports on the authors' experience gained in deriving a reference model for command, control, communication, computers and intelligence (C41) architectures. The reference model addresses a dilemma faced by organisations today: choosing the right distributed object platform for domain-specific applications. In making such a choice, organisations face both technological and market uncertai... View full abstract»

    Traditional systems development methodologies are not focused on the development of distributed systems. However, efforts to address these problems are going on within OMG, with the focus to standardise a meta-model for analysis and design methodologies. The initial submissions converged into a meta-model of Unified Modeling Language (UML), which is emerging as the standard from OMG. This meta-mod... View full abstract»

    The paper describes an environment for interactive configuration management of the software components comprising a distributed enterprise application. The environment permits one or more managers to view and modify the structure of components in terms of component instances, their allocation to hardware nodes and the bindings between their interfaces. The graphical management is based upon the Da... View full abstract»

  • Virtual private resources. An approach for long-term binding of services

    Current approaches for service mediation, such as trading, do not provide means for a long-term binding of services. They do not ensure that certain services are provided and that the desired service properties are fulfilled. Moreover, a server may withdraw a service offer at any time. For the integration of external services into an enterprise internal service market, it is necessary to guarantee... View full abstract»

  • Electronic contract negotiation as an application niche for mobile agents

    We propose electronic contract negotiation-a sub-part of the more general area of electronic commerce-as an example application for mobile agents. We start by presenting a set of requirements that an application should fulfil in order to take advantage of mobile agents and show that not all distributed applications meet these requirements. We then present contract negotiation, an example of an app... View full abstract»

    This paper reports on applying the ODP enterprise viewpoint in the domain of tele-education. The work is conducted as part of a research activity that aims at designing a tele-education system to support planning, execution and evaluation of dynamic distributed educational processes.

    The Internet and the World Wide Web (WWW) have elicited the explosion of accessible data repositories. Because high connectivity is now a reality, the challenge has been to take advantage of it to enable data sharing in a cost-effective way. Any proposed architecture would have to allow dynamic couplings of heterogeneous databases based on their content and interest. The authors propose an impleme... View full abstract»

    CORBA enables objects to interact in a transparent manner according to location and heterogeneity. However, this kind of platforms lack mobility functions. That is why the author proposes a solution based on a generic implementation of CORBA's LifeCycle service. The mechanism relies on intermediary objects that are used to encapsulate mobility management View full abstract»

    Previous work on long-running transactions for multi-database environments relaxes the isolation requirement of conventional ACID transactions. However, most of that work does not provide mechanisms to explicitly enforce isolation. This paper proposes a framework in which long-running transactions can specify global predicate-based locks to enforce limited forms of isolation between selected trans... View full abstract»

    One of the most important CORBA services defined by the OMG is the Object Transaction Service (OTS) which augments the CORBA object model with the notion of distributed transactions. The implementation design of the OTS is critical for the service to be really effective for applications. A good design suggests that the OTS should be part of the ORB (object request broker) itself rather than on top... View full abstract»

    IT systems play an ever increasing role in business, commerce, government and services, and can be involved in making decisions that carry enormous implications. This implies that these machines carry responsibility for those decisions and for their outcomes. This paper considers the implications of such “machine responsibility” both for the enterprise concerned and for the IT system, ... View full abstract»

    The goal of enterprise modeling is to capture the structure and operations of a business as simply and directly as possible. The object-oriented approach to enterprise modeling allows us to capture the structure and operations of a business as a collection of interacting business objects. The enterprise model provides us with useful insights into the workings of a business and hence facilitates ex... View full abstract»

    Enterprise level QoS issues are discussed, from which QoS evolution paths are derived. Service level QoS issues are identified and they have been studied as apart of service quality issues in TINA service architecture. TINA stream binding and its role in the TINA QoS framework are presented. A soft guarantee of stream quality is proposed, which does not require strict resource reservation. Soft gu...
