TL;DR: In this paper, a new architecture capable of utilizing the existing twisted pair interface between the customer services equipment and the local office is used to provide a vast array of new services to customers.
Abstract: A new architecture capable of utilizing the existing twisted pair interface between the customer services equipment and the local office is used to provide a vast array of new services to customers. Using an intelligent services director (ISD) at the customer services equipment and a facilities management platform (FMP) at the local office, new services such as simultaneous, multiple calls (voice analog or digital), facsimile, Internet traffic and other data can be transmitted over the existing single twisted pair using xDSL transmission schemes. New services such as the implementation of Internet connectivity, videophone, utility metering, broadcasting, multicasting, bill viewing, information pushing in response to a user profile, directory look-up and other services can be implemented via a network server platform via this architecture. A network server platform for hosting a plurality of services comprises, for example, a memory for storing a user profile, the user profile containing interests of a user, and for storing information related to their interests and a controller for controlling the collection of information from information servers and for pushing the collected information to the user in accordance with their defined priority.

TL;DR: Draws on some of Hyperion’s recent experience in helping to launch electronic commerce services on the Internet, reengineering of financial institutions and electronic cash, to suggest approaches for organizations wishing to participate in this new “marketspace.”
Abstract: Financial services is undergoing a period of unprecedented change ‐ new products, new entrants, mergers and acquisitions, downsizing … and now another new delivery channel: the Internet. The performance attributes of the Internet are related to both the needs of consumers and the nature of financial services products. Suggests loans, cross‐border services, payments and “knowledge/advice” as areas of opportunity in the early development of this new marketplace. Explores scenarios for the future development of “bancassurer” offerings and for electronic commerce as a whole. Draws on some of Hyperion’s recent experience in helping to launch electronic commerce services on the Internet, reengineering of financial institutions and electronic cash, to suggest approaches for organizations wishing to participate in this new “marketspace.” While businesses can now begin to develop strategies for exploiting cyberspace, argues that existing organizational structures may be inappropriate.

TL;DR: In this article, the authors describe functionalities required for real-time group communication services and present an implementation based on Sun Microsystem's Java 2 programming language, focusing on the high-level functionalities and abstractions, but also describe an object-oriented programming model for group communication systems.
Abstract: The World Wide Web has evolved from a distributed hypertext system to a platform-independent graphical user interface that integrates many network services. So far, its technology has restricted it mainly to applications for information retrieval. As networks become ubiquitious and more and more users have a permanent connection, there is an increasing demand for other network services, such as real-time data feeds, group communication, and teleconferencing. So far, these services have been provided by various proprietary software systems, which were hard to set up and use, and thus not very successful. Integrating real-time group communication services into the World Wide Web is a natural way to make them more accessible and will take the Web a step further on its way to becoming the universal network application. In this paper, we describe functionalities required for these services and present an implementation based on Sun Microsystem's Java 2 programming language. We focus on the high-level functionalities and abstractions, but also describe an object-oriented programming model for group communication systems.

TL;DR: Some of the architectural options that must be carefully considered in order to deliver Internet protocol (IP) services to such users in an efficient yet flexible manner are reviewed.
Abstract: The current state of the art in digital broadband access technologies to support emerging telecommunications services makes imminent the introduction of interactive broadband services-including data, video and the Internet-into the residential market. Over the last few years, much attention has been paid to the development of media access control protocols for cable TV networks that will allow the immediate support of broadband data services as the first step toward enhanced communications services for residential users. We review some of the architectural options that must be carefully considered in order to deliver Internet protocol (IP) services to such users in an efficient yet flexible manner. Future residential cable data services are expected to deliver Internet access, work-at-home applications, small business access, local area network LAN-LAN interconnect, and LAN emulation services over cable (CATV) networks.

TL;DR: In this article, the authors argue that support for manageability has to be considered at the design stage if services are to be capable of delivering high levels of quality of service for their users.
Abstract: This paper focuses on the management aspects of Web service provision. We argue that support for manageability has to be considered at the design stage if services are to be capable of delivering high levels of quality of service for their users. Examples of the problems caused by lack of manageability include maintenance operations that necessitate service downtime, or difficulties in ensuring consistency of information. We categorise management issues into those concerning a site as a whole and those pertaining to individual services. Our approach to site management supports the arbitrary distribution of services to machines, allowing the optimum cost/performance configuration to be selected. Services can be easily migrated between machines, resulting in sites that scale, both in terms of the number of services and the number of users. Service management issues may be generalised as supporting evolution, for example, supporting changes to the functionality, the presentation logic, and the overall look and feel of a service. Our approach, based on the separation of functionality and presentation, allows such changes to be performed on-line and ensures that updates are reflected consistency across the various pages of a service, or across services. This approach also facilitates the development of services that utilise dynamic content for service customisations, such as tailoring a service to match the profile of users. Furthermore, all management operations are available through Web-based interfaces, making them accessible to a broad range of users, not only specialist system administrators.

TL;DR: This paper presents a framework for management of distributed applications and systems based on a set of common management services that support management activities, which include monitoring, control, configuration, and data repository services.
Abstract: A distributed computing system consists of heterogeneous computing devices, communication networks, operating system services, and applications As organisations move toward distributed computing environments, there will be a corresponding growth in distributed applications central to the enterprise The design, development, and management of distributed applications presents many difficult challenges As these systems grow to hundreds or even thousands of devices and similar or greater magnitude of software components, it will become increasingly difficult to manage them without appropriate support tools and frameworks Further, the design and deployment of additional applications and services will be, at best, ad hoc without modelling tools and timely data on which to base design and configuration decisions This paper presents a framework for management of distributed applications and systems The framework is based on a set of common management services that support management activities The services include monitoring, control, configuration, and data repository services A prototype system built on the framework is described that implements and integrates management applications providing visualisation, fault location, performance monitoring and modelling, and configuration management The prototype also demonstrates how various management services can be implemented

TL;DR: A shift from face-to-face human contact to human-machine interaction; from paper-based information transfer to electronic delivery; from text-centered mode to multimedia; and from physical presence to telepresence or virtual presence is seen.
Abstract: Emerging technologies, notably the Internet and World Wide Web (WWW), have profoundly changed the way we work, live, collaborate and communicate. [1] With the rapid growth of the Internet and the Web, we have seen a move toward a new communication paradigm: a shift from face-to-face human contact to human-machine interaction; from paper-based information transfer to electronic delivery; from text-centered mode to multimedia; and from physical presence to telepresence or virtual presence. Another significant impact caused by the Internet is the creation of a virtual global community. This community bears some resemblance to the existing, physical world but is more dynamic in nature.

TL;DR: This work describes the experience with the deployment of a system that gives the home consumer broadband access to community content as well as to the Internet and derives a blueprint for a general architecture for managing federated services.
Abstract: The explosive growth of the Internet, widespread use of the World Wide Web, and a trend towards deployment of broadband residential networks are stimulating the development of new services such as interactive shopping, home banking, and electronic commerce. These services are federated since they depend on an infrastructure that spans multiple independent control domains. Managing federated services and providing effective support to the customer of these services is difficult, because only a small part of the environment can be observed and controlled by any given authority. We characterize different dimensions of this problem, using our experience with the deployment of a system that gives the home consumer broadband access to community content as well as to the Internet. This type of system is referred to as Broadband Interactive Data Services or BIDS. We then focus on diagnosis and describe a customer support tool that was developed to partially automate diagnosis in BIDS. We use the experience with this tool to derive a blueprint for a general architecture for managing federated services. The architecture is based on service contracts between control domains.

TL;DR: The Java Agent Environment — JAE is introduced, a multi-agent system comprised of mobile agents communicating with a fixed infrastructure of agent servers making services provided through the Internet accessible.
Abstract: Mobile agents offer unique opportunities for structuring and implementing open distributed systems. This new paradigm is an alternative to Remote Procedure Calls used in client/server systems. Consequently a wide range of applications are perfectly suitable to be implemented through mobile agent technology, e.g. electronic commerce. This paper introduces the Java Agent Environment — JAE, a multi-agent system comprised of mobile agents communicating with a fixed infrastructure of agent servers making services provided through the Internet accessible. An important constituent of this architecture is the exploitation of existing trader systems.

TL;DR: A framework for an expanded model of the information counselor role integrating information diagnostic and repackaging services is presented and it is suggested that corporate librarians serve as information counselors on multifunctional project teams.
Abstract: The outsourcing of information services challenges corporate libraries to shift their focus toward those services that are not readily “outsourcable.” An analysis of library services indicates that the diagnostic level of service is potentially the least outsourcable. To effect this level of service, it is suggested that corporate librarians serve as information counselors on multifunctional project teams. A framework for an expanded model of the information counselor role integrating information diagnostic and repackaging services is presented.
