Autonomous system control for a distributed switching node

This paper describes the main techniques that prevent the influence of a fault in an autonomous distributed system from spreading to the whole system. Several inter-subsystem communication methods are proposed and evaluated. From the standpoints of fault processing and processing load, frames should be sent though a data link over an ATM connection and when a fault occurs the link should be switched over without loss of data. A pilot system attains sufficient reliability without an excessive number of dynamic program steps. This autonomous control method will lead to a highly reliable switching node system with a large capacity
