  • Design of a middleware service for scalable wide area network applications

    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...

    The Turkish Navy (TN) has started an initiative to build a new middleware as part of a generic CMS development project named GENESIS. This middleware should satisfy the requirements of CMS applications that should run in a heterogeneous distributed computing environment. It should also be flexible enough to support existing applications. The approach was to use Off-The-Shelf (OTS) components and o... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (816 KB)

    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»

    The paper presents an information retrieval system for use by the Global Change Master Directory. The GCMD is a repository that contains Earth Science data collected by various agencies worldwide. The GCMD does not house the actual data, it contains descriptions of the data including the location of the actual data set. The GCMD also provides search services to locate these data descriptor files. ... View full abstract»

    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 paper provides a comparison of the basic DO (distributed object) concepts, namely “object”, “instance” and “class” used in various standards of the DO world. Two families of standards are identified: those related to the modelling aspects (MOF and UML) and those related to the architectural and implementation aspects (CORBA and Java). Moreover, the RM-ODP st... 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»

    Previously, the Object Management Group (OMG) has published a standard for a common object service, called the event service, to support decoupled and asynchronous communication between distributed CORBA object components. However, the service, albeit flexible, still suffers from a number of limitations. Among others, it has poor scalability, and it is not totally reliable. In view of these drawba...

    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»

    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»

    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...

    The Replication Logic is a set of protocols, mechanisms and services that allow a CORBA system to handle object replication. We present a specific implementation of a Replication Logic, namely Interoperable Replication Logic (IRL), which exhibits nice properties like non-intrusion (i.e., the replication logic is built “above” the ORB) and interoperability (i.e., a client can reside on ...

    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»

    A corporate Web site is the virtual representation of a corporation or organization on the Internet. Corporate Web sites face numerous problems due to their large size and complexity, and the nonscalability of the underlying Web infrastructure. Current solutions to these problems generally rely on traditional scaling techniques such as caching and replication. These are usually too restrictive, ho... View full abstract»

    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.
