    The impact of broadband ISDN (integrated services digital network) is assessed. It is pointed out that the key step in its introduction, i.e. the replacement of the copper wire infrastructure by optical fiber, is already taking place. Two alternative routes for the introduction of broadband services are described: the market-driven route and the investment-led route. The market-driven route entail... View full abstract»

    Five areas of technological advancement that affect network management are examined. They are: expert systems and machine learning/induction: fault tolerance; object-oriented databases; facsimile; and ease of use (user friendliness). The following points are emphasized. Machine induction will give network managers the opportunity to understand reasons behind actions instead of just seeing the resu... View full abstract»

    The author explains how X.25-based packet switching networks, whether public or private, can be upgraded to provide a point-to-multipoint (broadcast) service. He describes the experiences of a X.25 packet switching network vendor. He first deals with broadcast service access, discussing application concerns and requirements. He then presents networking alternatives and solutions and discusses broa... View full abstract»

    The authors review briefly the testing architecture of ISO 9646, a standard for defining testing methodology and architecture for all of the ISO Open Systems Interconnection layers. They then describe the test systems of the US National Institute for Standards and Technology for both the link and packet layers, and, for vendors interfacing their data terminal equipment to DDN. They explain how con... View full abstract»

    A heuristic, rule-based approach to network design is presented. The problem of designing high-performance packet radio networks by altering individual radio powers (i.e. by altering network connectivity) is considered. It is assumed that node locations, traffic requirements, and a multiaccess protocol are specified. The focus is on the dependence of capacity on connectivity for two reasons: conne...
