Abstract : This report summarizes the architecture and design developed for an adaptive fault- resistant distributed computing environment. A prototype Adaptive Fault Resistant System (AFRS) was developed as part of an ongoing investigation into using adaptive fault-tolerant techniques to improve the survivability of Battle Management/C3 systems. An Adaptive Fault Manager (AFM) is described. The ATM provides a capability to monitor and dynamically reconfigure a system in response to changes in its internal state (e.g., equipment failures) and/or changes that occur in the external environment. The enabling technologies that were exploited to implement this system are described, and a brief discussion of lessons learned is presented. A national Battle Management/C3 application was selected and modified to demonstrate the adaptive fault-tolerance concept. That application, Theater Missile Defense - Command and Control (TMD-CC), is also briefly described.
