Abstract

The authors discuss the design of a large-scale front-end computer in terms of system requirements, available technology, and the authors' experience with the ARPANET. The design is contrasted with that of the ARPANET TIP. Issues discussed include the choice of hardware configuration (CPU requirements, reliability, modularity, terminal interface units), what facilities to provide in the front-end, the communications protocol between front-end and Host, flow control on various inter-computer data paths, and data buffering strategies. The resulting system is being installed at the Research Computer Center at Bolt Beranek and Newman Inc.
