    The Spring name service does not prescribe particular naming policies; instead it serves as a foundation for building various policies. Our default policy is an environment containing name spaces for naming system-supplied objects, for a user's objects, for objects shared across applications, and for objects private to a process. Some name spaces are private, while others are shared. Any name spac... View full abstract»

    “Real world” group work occurs in a complex sociotechnical environment: CSCW and distributed systems have a word to say. This environment poses problems such as how to manage the whole system without having a master central element, how to support a diverse and large community of people, how to obtain information about different resources, how different systems can interoperate with un...

    In distributed systems, group communication among multiple entities is required in addition to the conventional one-to-one communication. Group communication protocols provide multiple entities with reliable data transmission service, i.e. messages are delivered to all the destination entities in the group. It is also important to guarantee that every application entity can receive messages in a w... View full abstract»

    We demonstrate that the typical problem of loss in performance due to disk I/O can be efficiently dealt with by using separate strategies for the storage of file data and data structures required for file management. Furthermore, to make the design very reliable, stable storage is provided. In fact the design is reliable to the extent that even after all types of hardware and software failures (ex...

    Widespread availability of IP multicast has renewed interest in structuring distributed applications around a group communication paradigm that exploits network-layer support for multicast applications. In the past, distributed systems that provided group communication supported a restricted group communication model. Such systems are either designed to provide reliable delivery with support for a... View full abstract»

    A key characteristic of mobile computing is that the end systems involved can experience differing degrees of connectivity during typical operational cycles. The paper discusses the issues associated with developing distributed system services to operate in such an environment. We focus on the provision of file system support and argue that existing file systems, including those developed for use ... View full abstract»

  • An ODP trading service for DCE

    Publication Year: 1994, Page(s):42 - 49

    The DCE Directory Service provides a dynamic white pages service, but DCE currently lacks a yellow pages service. A dynamic yellow pages service allows clients, at runtime, to find a required service by searching on service attributes. The ODP Trader provides such a service. We have implemented a trading service over DCE, which provides the basic ODP trading function and uses the operation signatu... View full abstract»

    We propose an architecture for an embedded adaptive scheduler in a heterogeneous workstation network. The generic architecture is applicable to various balancing problems arising in a distributed environment. As an example we introduce an adaptive job scheduler. The scheduler gives recommendations for a non-preemptive job transfer between the participating workstations. A neural network algorithm ... View full abstract»

    Because we like to run the AFS distributed file system on dataless clients at our homes, it is vital that the meager bandwidth available be used effectively. This makes Rx, the AFS remote procedure call package, a critical link in the overall system performance chain. We report on progress in adapting Rx to networks characterized by low bandwidth, high delay, or variable round-trip time. When we s... View full abstract»

    Networks such as the Internet and the telephone system are examples of ubiquitous large networks. While such networks are quite common, what is not so common is completely scalable, non-hierarchical naming that is independent of the entities location or affiliations. The problem of providing a unique, logical name for each nameable entity that can be kept immutant over the lifetime of the entity h... View full abstract»

    The trading function is an important function which specifies the trading service in open distributed systems. A trader is an object which provides the trading service. In the client-server model, the trader allows clients to locate servers dynamically and allows servers to advertise their services. A reliable trader is particularly important, because if the trader fails, clients could not find su... View full abstract»

    The paper presents a dynamic load sharing implementation based on OSF (Open Software Foundation) DCE (Distributed Computing Environment). Although DCE provides a wide spectrum of services for developing distributed application, DCE does not provide load sharing services. The proposed algorithm makes use of the technique of threshold and a smoothing function to reduce the overhead incurred by workl... View full abstract»

    Service interaction in open distributed processing (ODP) environments is difficult to visualize. Interaction often takes place asynchronously and new participants can join the system at any time. If errors are apparent in an interaction, debugging usually takes place through each service involved in the exchange. When peer-to-peer systems involve more than a couple of parties, this technique is of... View full abstract»

    We have designed and built a modular and extensible multi service storage architecture (MSSA) which allows evolution from, and compatibility with, traditional applications. The MSSA comprises a two-level hierarchy of storage servers with value-adding service layers above them. We present the access control mechanism of the MSSA. Access control lists (ACLs) are used to allow fine grained expression... View full abstract»

    Local area networks use a broadcast media to transfer messages between hosts. This allows for network snooping by unlisted parties. This paper proposes a novel way for cheaply replicating services in a local area network via snooping. We present a tool for the warm backup of files that employs network snooping for data dissemination. The tool allows for a selective replication of files in the syst... View full abstract»

    The NIST EXPRESS server is a computational facility at the National Institute of Standards and Technology (NIST), which provides the ability to run toolkit-based applications remotely. Users e-mail EXPRESS schemas and other data files to the server, which runs the requested applications on the files and returns any diagnostics or output. Applications requiring interaction can either be returned vi... View full abstract»

    Any architecture and infrastructure will implicitly embody certain concepts of the system life-cycle, of integration and of management that will be reproduced in any service that is developed on, or uses, them. Furthermore, the implicit assumptions in the architecture and the infrastructure might conflict. This is an architectural issue that is now recognised in the distributed system community, a...

    The paper investigates a mechanism that allows distributed programs to reduce their network usage by moving code segments between computers. The idea of moving code is developed into an abstract model of distributed computation called the Ship Model that has a basic entity called a ship. Ships contain code and data and are somewhat like objects that can migrate. The term `ship' is used to emphasiz... View full abstract»
