Abstract:

The ARPA network consists of a Network Control Program NCP which handles Host to Host communications, a LOGGERSERVER for providing access to a CP virtual machine from the network, and a user subroutine package for communicating with other Hosts on the network form a logged on CP virtual machine operating in the CMS environment. The NCP and the LOGGER each run in separate virtual machines the NCP handling the IO operations with the IMP and the LOGGER handling pseudo IO operations with CP through a software supported virtual terminal device. CMS virtual machines communicate with the NCP virtual machine through a special virtual machine to virtual machine communications facility. The report describes the routines which make up the NCP and the LOGGER.
