    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»

    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»

    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»

  • An implementation of CORBA's LifeCycle service

    Publication Year: 1997, Page(s):111 - 117
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (512 KB)

    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»

    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»

    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»

    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»

    A communication infrastructure for enterprise information systems requires not only interoperability but also high reliability. An effective way to allow for differences in operation time and administrative policies is to provide a nonblocking communication interface. In the CORBA 2.0 specification, however, non-blocking communication is not defined as a delivery reliability aspect. The OMG is wor... 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...

    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»

  • Can CORBA fulfil data transfer requirements of industrial enterprises?

    Publication Year: 1997, Page(s):129 - 137

    The globalization of industrial enterprises leads to problems caused by the heterogeneity of hard- and software. To overcome these problems, distributed platforms can be used. Yet, much work remains to be done on distributed platforms before they actually can meet industrial needs. For example, there is no standardized mechanism for asynchronous data transfer and no possibility to transmit so-call... View full abstract»

    The Component Object Model (COM) (and by definition, DCOM) is the only component system where there is a significant market for commercially available components. This paper discusses the elements of COM's design that have all contributed to making COM such a viable commercial reality: black box-encapsulation, interfaces, interface immutability, multiple interfaces, and location transparency View full abstract»

    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»

    Meta-modeling is critical to the success of distributed object environments such as CORBA and ActiveXI DCOM. However, there is a surprisingly large variation in the nature of the meta-models (and meta-meta-models) that have been proposed for such environments. This paper investigates this phenomenon by examining the basic tenets of meta-modeling in the context of distributed object environments, a... 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 presents the development of a distributed architecture for the factory automation domain by applying the object-oriented domain engineering (OODE) method. The first part of the paper talks about extending formally defined object-oriented analysis and design (OOA&D) methods with domain engineering (DE) concepts. It defines the resulting OODE workflow, deliverables, and development cyc... View full abstract»

    A common problem in distributed systems is the selection of a particular service instance from a set of possible services. In this paper, we identify the kinds of information required to select services within enterprise distributed systems and present a flexible mechanism for selecting services. This mechanism enables clients to build complex queries that are able to utilise script-based interact... View full abstract»

    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»
