Abstract​

RFC 7 is a working paper on the preliminary software design of the Host-IMP (HI) interface, written at UCLA in May 1969. Its stated object is to outline the specification of the Host-IMP interface programs. It describes the two main programs of the system — the Network program, which multiplexes the outgoing and distributes the incoming messages and prepares the 16-bit Host heading, the word-boundary marking and the 1006-byte segmentation of outgoing text, and the Handler program, which drives the channel hardware unit and empties the buffers filled by the Network program — together with the pool of buffers and the ring-shaped interface table through which the two exchange data. It closes with open questions on the control procedure between HOST and IMP, on where the special channel hardware unit is to be connected, and on the availability of the Gordo documentation.
