On Packet Switching for Communication Systems

Abstract

Packet switching techniques are reviewed in the context of computer communication networks. Communication systems, in the form of networks of terminals, based on packet switching techniques are then examined and their design parameters analysed. Such systems are compared with voice communication networks from a cost/performance point of view. The nature of long-distance communication in packet switching networks is discussed. Quantitative estimates are made with reference to a 400-node network with 20,000 terminals. The role of message switching in these networks is also covered.
