On Distributed Communications

II. Digital Simulation of Hot-Potato Routing in a Broadband Distributed Communications Network

Cover Image

By: Paul Baran, Sharla P. Boehm

One in a series of eleven Memoranda detailing the Distributed Adaptive Message Block Network, a proposed digital data communications system based on a distributed network concept. It describes preliminary computer simulation of a message routing scheme investigated as part of a study of ways of reducing the vulnerability of command and control communications networks. This routing doctrine, referred to as the “hot-potato” switching doctrine, differs from normal store-and-forward switching in that it permits an apparent real-time transmission of data even though it itself uses store-and-forward techniques.
