Cable Bus Applications in Command Centers

摘要

Microprocessor technology has advanced to the extent that the three or four lowest layers of a typical long-haul network protocol architecture may be implemented on one microprocessor-based circuit board. The impact of this evolutionary step on the capabilities of microprocessor-based networks will be profound. This report documents the FY 79 activities of a MITRE/DCA program to determine the applicability of such a futuristic microprocessor-based cable bus local area network to World Wide Military Command and Control System (WWMCCS) command centers. The major emphasis of this program has been on a comparative analysis of cable bus and message switch local area network architectures. Potential cable bus and message switch command center applicability is measured here is terms of security, functionality, reliability, cost, flexibility and performance. Specific tasks during FY 79 included the installation of a cable bus test bed with a gateway to the ARPA network, measurement of cable bus performance, and partial implementation of a cable bus protocol architecture.
