Fault Tolerance in Networked Control Systems Through Real-Time Restarts

Abstract

Networked control consists of sensors and actuators that interact with the "real world" environment (plant), which are connected to each other and to with controllers over digital networks. Such systems are long-running, have real-time requirements, and should function in a correct and timely manner even in the presence of failures and software upgrades. Arguably, the growth and the widespread use of the Internet, the largest operational distributed system today, has been enabled by its fault-tolerant properties such as robustness to router and link failures. As such systems take on an increasingly critical role, supporting local and national infrastructures, homes and industries, the importance of reliability and availability issues grows.
