Development of the Digital Engineering Laboratory Computer Network: Host-to-Node/Host-to-Host Protocols
A 1981 technical report from the Air Force Institute of Technology's School of Engineering, issued through the Defense Technical Information Center, on protocols linking host computers to network nodes and to each other in the Digital Engineering Laboratory computer network. The pictures are rotated data-flow diagrams drawn as circles for processes, arrows for data flows, and underlined labels for buffers, with dashed lines marking multiple channels. A designer could borrow their clean boxes-and-arrows conventions for explaining a system's flow of inputs, buffers and outputs.
