    A personal view of an extended concept of personal communications is discussed. The relationship between low-power digital cordless technology and some alternatives (analog cordless, digital mobile radio, and cellular mobile radio) is examined. Personal communication network (PCN) power requirements, circuit quality, level of network integration, and access to network intelligence (e.g. call forwa... View full abstract»

    The economic feasibility of using SONET self-healing-ring (SHR) architecture in survivable interoffice fiber networks is studied. The model used is discussed, and the selection criterion for the candidate area in this study, the SHR cost model, the hubbing network cost model, the network survivability measure, and the network growth model are described. Results of two case studies based on a metro... View full abstract»

    A possible methodology for network security design is investigated. The ideas for each phase of the method-specification, design, and implementation-are described in detail. An attempt is made to apply the method to an invented example. Several pitfalls that await the requirements specifier are discovered. One problem is that defining and classifying security services is not as straightforward as ... View full abstract»

    How to introduce packet switching into ISDN and, in particular, whether frame switching should be privileged are addressed in the context of NUMERIS. In addition to 64-kb/s access to Transpac, the national packet-switching public data network (PSPDN), it has been decided to offer packet-mode data communications services on the D channel of the user access to provide access to switching facilities ...

    A set of performance specifications that seem appropriate for real-time computer communication services is proposed. They include various types of delay bounds, throughput bounds, and reliability bounds. Other requirements and desirable properties are described from a client's viewpoint, and the ways in which each requirement is to be translated to make it suitable for lower levels in the protocol...
