On the Packet-Interleaved Interface Between Packet-Switched Network and Computers

This paper describes a study of transmission control procedure for computer-to-computer and computer-computer-to-terminal communication through a public packet-switched network. Four types of basic data link are defined over a packet travel path in the network, and the functions required for the data link are discussed. A process number and its associated control method are proposed as a method of packet-interleaved communication. By applying the result of the discussion and introducing the concept of a data link and a process number, a transmission control method and a call control method between packet-switched network and computers are proposed for the packet-interleaved communication on the basis of the HDLC procedure (high-level data link control procedure).
