Telecommunications

Advances in telecommunications have rapidly brought nations together to share in research, development, and cultural exchange. RAND research on telecommunications includes development of satellites, surveillance, and other new technologies, as well as related questions of standards, authority, and the rights to private data.

    Cost Estimate

    The tenth in a series of 11 memoranda detailing the Distributed Adaptive Message Block Network, this volume provides a cost estimate for the proposed system, based on an arbitrary network configuration of 400 switching nodes, servicing 100,000 simultaneous users via 200 multiplexing stations. Assuming a usable life of ten years, all costs are estimated at about $60,000,000 per year.

    Introduction to Distributed Communications Networks

    The first in a series of 11 memoranda detailing the Distributed Adaptive Message Block Network, this volume introduces the system concept and outlines the requirements for and design considerations of the distributed digital data communications network. It considers especially the use of redundancy as a means of withstanding heavy enemy attacks.

    Tentative Engineering Specifications and Preliminary Design for a High-Data-Rate Distributed Network Switching Node

    The seventh in a series of 11 memoranda detailing the Distributed Adaptive Message Block Network, this volume considers the specifications of the proposed system's switching node. Timing calculations, together with a projected implementation scheme, provide a strong foundation for the belief that the construction and use of the node is practical.

    The Multiplexing Station

    The eighth in a series of 11 memoranda detailing the Distributed Adaptive Message Block Network, this volume describes the multiplexing stations which connect subscribers to the switching nodes. The network will simultaneously process traffic from up to 1024 separate users sending a mixture of start-stop teletypewriter, digital voice, and other synchronous signals at various rates.

    Digital Simulation of Hot-Potato Routing in a Broadband Distributed Communications Network

    The second in a series of 11 memoranda detailing the Distributed Adaptive Message Block Network, this volume describes a computer simulation of the message routing scheme proposed. The basic routing doctrine permitted a network to suffer a large number of breaks, then reconstitute itself by rapidly relearning to make best use of the surviving links.
