IBM's Token-Ring LAN (Local-Area Network) -- A Base-Level Communications Solution

摘要

This document reviews the computer revolution and information explosion within the Air Force and their part in increased data communications requirements. It investigates the local-area network topologies for capabilities and characteristics that are advantageous in a CONUS, non-secure, base-level configuration. Focused upon are the bus and ring topologies. Then a closer examination is made of a hybrid star-ring local area network (LAN) utilizing a token-access control mechanism. This LAN, as proposed by IBM, is seen to have superior maintainability, reliability, and flexibility. (Author)
