The Interface Message Processor Program.
Abstract
The ARPA Network has been in operation for almost eight years and has become an international facility. The network has grown to more than sixty sites spread across the continental United States, plus satellite connections to Hawaii, Norway, and England, and is steadily growing; approximately one hundred independent computer systems of varying manufacture are interconnected. Provision has been made for terminal access to the network from sites which do not enjoy the ownership of an independent computer system. Implementation of the IMPs required the development of a sophisticated computer progam. This program has been previously described in. As stated then, the principal function of the IMP program is the processing of packets, including the following: segmentation of Host messages into packets; receiving, routing, and transmitting store-and-forward packets; retransmitting unacknowledged packets; reassembling packets into messages for transmission into a Host; and generating RFNMs and other control messages. The program also monitors network status, gathers statistics, and performs on-line testing.
