Abstract : This report describes the function of a Network Control Program (NCP) in the Advanced Research Projects Agency Computer Network (ARPANET), and surveys several representative implementations of such programs. The network control program is the operating system module that interfaces user programs to the communications network by providing system calls to invoke communications functions specified by the network-wide host-to-host protocol. The purpose of this report is to document the implementation of the network control program and the optional strategies used in different implementations. This report should be of use to individuals implementing network control programs for other computers, and to individuals designing network control programs for other computer networks. The ARPANET is an advanced computer communications system connecting together a set of computer centers in the United States and Europe. The following description of the network touches on several aspects: the physical implementation, the scope and size, and the functional goals. Additional keywords: packet transmission.
