    The impact of buffer management and priority scheduling is examined in stressful scenarios when the aggregate incoming traffic is higher than the output link capacity of an Asynchronous Transfer Mode (ATM) traffic shaper. To simultaneously reduce cell loss and extreme delay behavior for two or more classes of service, we show that a dynamic priority scheme is required. We propose a scheduling algo...

    Benes networks are known to be nonblocking rearrangeable networks which can realize arbitrary permutations. Topological equivalence extends the nonblocking rearrangeability to a class of multistage interconnection networks (MIN), which has the same topology as Benes networks. There is another class of well-known multistage interconnection networks, which is not yet known as either nonblocking rear... View full abstract»

    Congestion avoidance is one of the key issues for the effectiveness and reliability of high-speed networks. The design of congestion avoidance mechanisms is usually based on some assumptions of the traffic model and the performance is strongly influenced by the related parameters. Such parameters are usually initialized subjectively and adjusted by applying some predefined linear transformation to... View full abstract»

    In an object oriented, distributed environment, program maintenance, which has never been the most predictable task, becomes even more uncertain. Java's dynamic loading mechanism was developed to tackle some of the uncertainties. In doing so, it shifts the focus from the state of the sources to that of the binaries. This paper discusses some of the implications of that move View full abstract»

    CORBA is currently the most popular middleware platform. Due to the progress and acceptance of mobile communications, it is inevitable to offer CORBA services for mobile terminals, especially over a wireless link. The Object Management Group, the standardization body for CORBA, already requested proposals for extending CORBA in the wireless environment, leading to several submissions. However, the...

    We describe a distributed system architecture that supports the integration of different front-office trading systems with middle and back-office systems, each of which have been procured from different vendors. The architecture uses a judicious combination of object-oriented middleware and markup languages. In this combination an object request broker implements reliable trade data transport. Mar...

    This paper presents a model-based approach to support service creation. In this approach, services are assumed to be created from (available) software components. The creation process may involve multiple design steps in which the requested service is repeatedly decomposed into more detailed functional parts, until these parts can be mapped onto software components. A modelling language is used to... View full abstract»

    Network-centric computing involves fundamental changes at many levels that amount to a substantial paradigm shift in computing. Creative approaches and competent strategies to manage the network-centric environment at both the instructional design and user levels need to be established and understood in order to ensure a degree of quality comparable to what we had before.

    Active networks are an example of a wide area distributed system. The objects in this system require platform independent machine-readable, flexible behaviour specifications. Current mechanisms in CORBA, DCOM and similar technologies are not adequate. We demonstrate for the first time how specifications with the required properties can be written in XML, the new language of the WWW View full abstract»

    Distributed software systems need to evolve according to the ever-changing requirements on which they were built. Software systems' tailorability can be achieved in terms of component software. Atoms and molecules the basic constructs of the ATOMA framework are the building blocks for distributed tailorable component-based software systems. These constructs can be considered as independent agents,... View full abstract»

    Telecommunication systems these days are moving from static wide area component structures towards highly dynamic mobile infrastructures. This shift requires new algorithms to interconnect these mobile entities/components and route messages between them. In this paper we describe a naming and routing algorithm which can be used in fine-grained mobile component systems. As a case we use a homogenou... View full abstract»

    Due to the rapid growth of World Wide Web applications on the Internet, a web server may encounter the situation that a huge number of connection requests coming in within a very short period of time. We call it the “connections explosion”, which usually causes the web server system overload or even to crash if the problem were not prevented in advance. This article presents a dispatch...

    This paper describes an architecture that provides support for quality of service (QoS) in open systems. The Quartz QoS architecture aims to avoid the dependency on specific platforms that limits the application of most existing QoS architectures in open, heterogeneous and distributed systems.

    Present-day object-oriented middleware provides little support for the distribution, replication and caching of the state of a distributed object. This makes these platforms unsuitable for the development of large-scale distributed applications. We argue that the model of distributed objects on which these middleware platforms are based hinders the addition of comprehensive distribution and replic... View full abstract»

    In this paper we introduce JWire, a new component model for Java. JWire is designed for building dynamic architectures of components that use an open set of binding and communication protocols, and supports the use of architectural styles in assembling components. Using JWire, a system is composed of “wireable” components that each encapsulate state and behaviour behind an interface de... View full abstract»
