Interface Message Processors for the ARPA Computer Network

Abstract

The ARPA computer network is a packet-switching store-and-forward communications system designed for use by computers and computer terminals. This report describes aspects of the work in network operation; Terminal IMP access control and accounting; Private Line Interface design, construction, and checkout; Pluribus IMP construction and checkout; sizeable changes to the IMP message-processing algorithms; and Satellite IMP issues. The IMP message- processing algorithms have been completely redesigned and the operational IMPs are now using a message-block scheme on a Host-pair basis, rather than the previous IMP-pair message number scheme. The major topics addressed in the report on Satellite IMP progress are the Pluribus implementation and the acknowledgement scheme the authors have chosen for use on the broadcast channel.
