Internet Protocol Transition Workbook
Internet Protocol Transition Workbook is a 1982 technical workbook compiled by the Defense Technical Information Center, covering computer communications networks, gateways and installation planning. Its four pictures are plain line diagrams of networks joined by catenet gateways, hosts and access controllers, plus a geographic map of the ARPANET; a designer could borrow their node-and-link schematic language for network or infrastructure graphics.
