Abstract : Development of the Air Force Institute of Technology Digital Engineering Laboratory's local computer network (DELNET) was continued with requirements formulation, environment evaluation, organization and structure design, network node software implementation, and host software design. System requirements were evaluated from an implementor's viewpoint. System organization and protocol structure emphasized the International Standards Organization's Reference Model of Open Systems Interconnection protocol standard. A locally developed network node, the Universal Network Interface Device (UNID), was advanced and confirmed as operative. Methodology was established for targeting node operating system software, packages consisting of both high order language Zilog PLZ/SYS and assembly modules, to the UNID. An initial node software package was organized and implemented. The study continued wth an evaluation of the host computer environment, applicable host requirements, and a map of the ISO protocol model on the DELNET topology. ISO model layers were defined for the DELNET, and design alternatives were suggested.
