    Distributed object computing (DOC) middleware, even if commonly used, has several drawbacks in supporting large and complex distributed applications: no visibility of distributed object interconnections, no implementation separation between business logic and system services, and no application deployment process. In response to this, DOC middleware is evolving to distributed component computing (... View full abstract»

    Adaptability is one of the most important challenges in modern distributed systems. It may be defined as the ease with which a software application satisfies the different system constraints and the requirements of users and other applications. Adaptability is needed because distributed systems are inherently open, heterogeneous, and dynamic environments integrating a wide range of platforms, oper... View full abstract»

    The mobile Aaent (MA) paradigm proposes several attractive solutions to deal with the problems of network-centric programming. Despite the availability of several MA platforms, there are still only a few MA-based distributed services. The paper claims that the lack of interoperability is one of the major obstacles to the large-scale diffusion of the MA paradigm, and discusses solutions to permit t... View full abstract»

    RT CORBA has been specified with the intention of supporting real-time (RT) distributed applications using diverse scheduling, resource access and synchronisation protocols. This work analyses how two specific synchronisation protocols may be implemented over RT CORBA, and concludes that it is not possible if the spirit of the RT CORBA specification is to be followed, and unless current operating ...

    This work is a case study. We describe how we are provisioning QoS in a real-time distributed object platform dedicated to power plant control applications. A previous experiment based on a modified Java-ChorusOS-ATM platform enhanced our knowledge on QoS based distributed object systems. We used RM-ODP/ReTINA as a distributed computing object model where time requirements are specified in terms o... View full abstract»

    Publication Year: 2000, Page(s):263 - 272
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (716 KB)

    Most distributed applications would greatly benefit from a middleware set of services to provide scalability, fault-tolerance, adaptability to network events, load balancing and real-time guarantees. However current distributed paradigms, like CORBA or RPC only provide the basic protocols and services for interoperability, and fail (intentionally) to define more complex relationships among an appl...

    XML has emerged as the universal standard for exchanging and externalizing data. Software products of all kinds are being upgraded to “support XML”. Typically this means they can import and export XML data. But just defining standard representations for exchanging data is insufficient. The data need to be integrated with existing applications and databases and processed by programs wri... View full abstract»

    In the world of pervasive computing where large management systems, as well as small devices, all become interconnected, the problem of the configuration and management of networks is becoming increasingly complex. System administrators have to deal with many problems due to the increasingly distributed architecture of systems. Jini, a new paradigm for the development and management of distributed...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (964 KB)

    RoamX provides support for the user-controlled management of a distributed X desktop, potentially spanning multiple administrative domains. Instead of terminating X-based applications and restarting them manually elsewhere, applications can be suspended and restored selectively on different machines while preserving their context and state. The migration of the GUI is accomplished by an extended v... View full abstract»

    The wide acceptance of object oriented environments and proposals has renewed interest in all the class inheritance related issues; in particular its implementation in distributed architectures. The paper focuses on how the inheritance relationship could impact on (possibly heterogeneous) distributed systems that do not assume co-residence of objects and their classes/superclasses. In these system... View full abstract»

  • Integrating meta-information management and reflection in middleware

    The representation and management of meta-information is an important issue in reflective architectures. In the case of complex base-level systems, such as middleware platforms, this issue becomes even more crucial, given the large number of entities of different kinds that must be dealt with and especially, given the fact that such entities are normally distributed, which makes it difficult to ma...

    An increasing number of applications are being developed using distributed object computing middleware, such as CORBA. Many of these applications require the underlying middleware, operating systems, and networks to provide end-to-end quality of service (QoS) support to enhance their efficiency, predictability, scalability, and fault tolerance.

    There are tremendous interests and activities in migrating distributed desktop applications to the Web to take advantage of its explosive opportunities. Many would think that the migration effort would be minimal if the application is built using an object oriented and platform independent language, such as Java. While there is less effort in porting a distributed Java application to the Web, the ... View full abstract»

    Distributed interactive simulation applications require the use of networked virtual environments that represent external systems, and that can perform processing or communications on behalf of objects in the entire environment. We want to develop distributed interactive simulation systems using the object-oriented software approach, and deploy these systems in a large-scale. The systems must sati... View full abstract»

    Adaptability and composition are two of the most important research areas in object-oriented systems. Whereas adaptability tries to cope with system evolution by adding/replacing components, composition tries to facilitate system building by placing together different components or pieces of software. Nevertheless, object-oriented languages do not provide enough support for the development of true... View full abstract»

    Mobile agent technology raises a new dimension in distributed database processing. Of interest in this paper are mobile procedures querying multiple databases distributed over a network. In the used execution model, mobile execution can profit from both migration, reducing amount of transmitted data, and data prefetching at the most beneficial site. To achieve the lowest response time, an executio... View full abstract»

    COALA is a new language for high level design of distributed object applications. The design concepts used in COALA are those of Coordinated Atomic Actions (J. Xu et al., 1995), which propose a unified transactional approach to structuring complex concurrent activities and supporting error recovery. COALA integrates several formal techniques (D. Buchs and N. Guelfi, 2000) in order to address verif... View full abstract»

    Decoupling the components of a distributed application through an intermediate shared data model is a powerful concept. Components can work independently, but at the same time share intermediate results and collaborate on a shared data structure. This paper describes a particular realization of the shared data model, the shared concept space (SCS), which is an essential element of the DIVA visuali... View full abstract»

    Database schema integration is significant not only in building multidatabase systems but also in data warehousing. Meta data, which define schemas, are normally involved in the surrounding issues. And while many of these issues have been addressed in the past, unresolved issues remain. The authors present an approach that not only uses metadata but also uses meta-meta information to make schema i... View full abstract»
