    Abstract
    Describes types of international gateways available for online searching. Public data networks are provided by national telecommunications authorities. Private data networks are run by an organization for its own use, or for customers of its services. Academic data networks are a special case of private networks which serve the the academic and research communications. Gives details of a number of academic networks: JANET, BITNET, NETNORTH, EARN, Internet. Describes the gateways between JANET and the UK public data network, EARN and Internet. Describes the international X.25 infrastructure (IXI) network which is organized by COSINE (Cooperation for OSI networking in Europe) programme which aims to provide OSI-based services for European researchers

    Abstract
    Technological and regulatory developments are opening the door for competition and new services in the local loop. The reunification of Germany created an opprotunity for Deutsche Telekom to install fibre in the loop on a large scale in eastern Germany. Deutsche Telekom's strategy consists of 4 steps: fibre in the loop is seen as a process innovation. New broadband services - product innovations - can be based on the process innovation. Only a sufficient number of installations will enable the industry to invest in new products. Besides the local networks equipped with fibre, there is an overlay network for the rapid delivery of fibre access for business customers. The experience gained in eastern Germany will be transferred to western Germany when tranforming its existing network structure

    Abstract
    Describes a layer model for networks. For each layer, one or more services are defined, and for each service a protocol is specified. 2 OSI application level protocols have been defined for library services: SR and ILL. The underlying layers are supposed to be OSI services, but some implementations are using TCP/IP, and some are using a mixture of OSI and TCP/IP. The systems based directly on TCP/IP can not communicate with those based purely on OSI. Discusses the pros and cons for choosing OSI or TCP/IP. Gateways between the OSI and TCP/IP networks are needed. The ISO protocol SR and the ANSI protocol Z39.50 are both 'search and retrieve' protocols. The SR is almost a subst of Z39.50, but they may become identical in the future. There is only one protocol for interlibrary loan, the ISO ILL protocol. It covers 3 models of interlibrary loan and all services connected with ILL. Other services such as Explain, Scan and Update are presently being discussed in ISO TC 46. Discusses the needs of the library community for network services such as file transfer, remote login, directories and electronic mail

    Abstract
    Describes the development of SuperJANET, the new optical fibre network for the UK academic and research community. Considers pilot applications for SuperJANET covering library and non library applications and strategic issues to be met for SuperJANET to become an information superhighway. Gigabyte networks will be 1.000 time faster than JANET and will enable sophisticated image and voice communication. SuperJANET uses synchronous digital hierarchy technology. SuperJANET is being developed and and introduced in a number of phases. Discusses supercomputing, library and information services, and strategic issues. Examines the role of technology and librarians in the development of the virtual library

    Abstract
    Discusses Austrian government policy on the information superhighway (ISH) since Aug. 94. The Austrian telecommunications infrastructure is far behind the standards of Europe. The Austrain PTT monopoly over the public telecommunications network is an obstacle to development. The rates for data services are still based on copper cable with transmission speeds of 9600 Kbps. Although there are various ISH initiatives in Austria, the gap between vision and reality is large. Describes the initiatives of the Austrian National Host and the Bureau for International Research and Technology Cooperation; the Austrian Platform for Telematic Applications; BNet (Burgenland); Telematik Initiative Wien; TELKIS Telekommunikationsinitiative Steiermark; Datahighway Upper Austria; Vorarlberger Telekommunikations GmbH; Telematik Initiative; Datenbahn Telecom GmbH (Salzburg); Ti-KOM (Tirol) and other initiatives

    Abstract
    The function of the W3, like that of Z39.50, is to offer access to networked information, and they appear to have similar client/server architectures. However, libraries need both because of the W3's lack of support for the advanced search, retrieval and management facilities that are expected of modern OPACs and are offered by Z39.50. Current research is involved in developing hybrid W3/Z39.50 services

    Abstract
    Adaptive, in-call, bandwidth reservation may be used to enhance bandwidth utilization in a policed asynchronous transfer mode (ATM) virtual path shared by traffic streams originated by many bursty sources. Presents a model, based on Markov-modulated sources and stochastic fluid methods, for performance analysis of the proposed mechanism. The model, corroborated by simulations, is used to study achievable bandwidth gain and the effects of feedback delay and competing reservation processes

    Abstract
    In Sept. 1990, the US Dept. of Education's Library Technology and Cooperation Grants Program awarded a three-year grant to the Florida Center for Library Automation (FCLA), an agency of the Florida State University System, to develop software adhering to the ANSI Z39.50 Information Retrieval protocol standard. The Z39.50 software was to operate over the OSI communications protocols and be integrated with FCLA's NOTIS system, which is shared by all 9 state universities in Florida. In order to test the correctness of its Z39.50 software, FCLA sought out other library software developers who would be willing to develop Z39.50 systems of their own. As part of this process, FCLA helped to found the Z39.50 Implementor's Group (ZIG), which has since gone on to improve the standard and promote Z39.50 implementations throughout much of the North American library systems marketplace. Early on in the project, it became apparent that TCP/IP would be a more heavily used communication vehicle for Z39.50 messages than OSI. FCLA expanded its design to include TCP/IP and, by the end of the grant in Sept. 1993, will have a working Z39.50 system that can communicate over both OSI and TCP/IP networks

    Abstract
    Describes the asynchronous transfer mode (ATM) protocol, technology and architecture, as well as the issues which it is designed to solve. Traces the evolution of ATM and examines the applications for which ATM is likely to be used. Describes comparisons made with alternative networking technologies and matters which require further solution
