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 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.By applying the result of the discussion and introducing the concept of a process number, a transmission control method and call control signalling method between computer and packet switched network are proposed for the packet interleaved communication on the basis of the HDLC procedure.
