A Software Implementation of a Satellite Interface Message Processor.
Eastwood, Margaret A.; Eastwood, Lester F., Jr.
A design for network control software for a computer network is described in which some nodes are linked by a communications satellite channel. It is assumed that the network has an ARPANET-like configuration; that is, that specialized processors at each node are responsible for message switching and network control. The purpose of the control software is to oversee network operations--for example to keep track of message queues and switching functions, to tag messages with addresses and insure that they arrive error-free, and to avoid disruption of network functions where a node or communications line is inoperative. The design presented is intended to insure both efficient use of the network communication resources and attractiveness to users. To achieve the goal of efficiency, the packet reservation scheme for computer communication by satellite is implemented. To gain the objective of attractiveness, the control software has been designed to make network operations essentially invisible to the user. (Author/DGC)
