Interprocess Communication Protocols for Computer Networks
A 1975 Stanford thesis by Carl Sunshine, catalogued by the Defense Technical Information Center, on interprocess communication protocols for computer networks, written for network engineers and researchers. The pictures are line diagrams of packet-switched networks: hosts, packet switches, gateways and network clouds linked by heavy and light connecting lines, with labelled nodes and a few schematic protocol stacks, offering a designer a clear vocabulary for node-and-link layouts.
