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 Hosts to other Hosts and accepts messages for its Hostss 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.
