TL;DR: The paper emphasizes the introduction of a subsection of the network layer: the internet layer, which will help LANs comply with the OSI Reference Model of the ISO.

TL;DR: The amalgamation of spread system and local area network techniques is presented, and the flexibility of the new approach is illustrated with respect to specialized applications.

TL;DR: A control algorithm suitable for slotted multiaccess schemes based on monitoring the channel transmissions is proposed, and a model is presented and the algorithm is analysed in detail.

TL;DR: The authors argue why network management is necessary, examine the difficulties involved, and take a look at the current standards work in the area.

TL;DR: The impact on local area networking of recent technological developments is discussed and four carrier services: cable television, British Telecom's IDA system, value added networks and public information networks are assessed.

TL;DR: The design of a hybrid encryption system to allow secure data transfer between computers in a communications network and a protocol sequence to establish a secure connection between the users in the network and to authenticate each other's identity is outlined.

TL;DR: The approach adopted by the National Computing Centre to solve the problems is presented, together with a description of the test environment, and the third party test service offered by NCC Comms-Aid is outlined.

TL;DR: The paper describes the US government's security policy and its implications for private organizations and the present status of information systems security.

TL;DR: The design of the Multilink network is described, followed by a review of the support software required for use with personal computers.

TL;DR: An explanation of the concepts involved in voice messaging systems is presented, and comparisons are made with conventional text and telephone communications systems.

TL;DR: A factory monitoring and control network has been installed by the electrical division of Lucas CAV and some of the teething problems they encountered are outlined, together with the modifications that were introduced as a result.

TL;DR: The provision of value added networks involves more than just supplying the network service itself, and some lessons learned from their operation are presented.

TL;DR: A network in a major London hospital with external links is described with particular emphasis on its evolution and the need for versatility with cost effectiveness.

TL;DR: An approach to the performance evaluation of a communication protocol operating in a concurrent environment is described and suitable performance indices are defined and the implementation of a software monitor embedded in the protocol is outlined.

TL;DR: The special bandwidth efficiency features of coded single carrier multilevel data communication signals pave the way for implementation of high speed data transmission via public analogue telephone networks and security of data on public networks is improved by advanced trellis coding.

TL;DR: An account is given of recent developments in the work towards publication of standards for data security, and a forecast of the progress to be expected in the future is concluded.

TL;DR: A multi-access scheme is proposed for handling priority-based messages in data communication systems through satellites using different schemes by which time slots are alloted by the satellite based on a 'priority index'.

TL;DR: An outline is given of simulation studies that have been carried out to demonstrate the feasibility and effectiveness of a congestion control scheme for implementation in an integrated services local area network.

TL;DR: The background to the design of the system and the facilities that it offers, the results of a programme to test the service, and the requirements for operating the system are outlined.

TL;DR: The paper sets out some of the current developments in the integration of voice and data services, with an emphasis on British Telecom's pilot Integrated Services Digital Network.

TL;DR: There is growing interest in the concept of electronic funds transfer at point of sale, i.e. the replacement of cash in everyday shopping transactions with an all-electronic alternative that must be highly secure.
