Interface Message Processors for the ARPA Computer Network

Abstract

The basic function of the ARPA computer network is to allow large existing computers (Hosts), with different system configurations, to communicate with each other. Each Host is connected to an Interface Message Processor (IMP), which transmits messages from its Host(s) to other Hosts and accepts messages for its Hosts(s) from other Hosts. There is frequently no direct communication circuit between two Hosts that wish to communicate; in these cases intermediate IMPs act as message switchers. The message switching is performed as a store and forward operation. The IMPs regularly exchange information. A High Speed Modular IMP is under development; one goal of this effort is to increase IMP performance by a factor of 10.
