A software fault detection and recovery in CDMA systems

This paper describes an approach to software fault detection and recovery in CDMA systems, which is based on the sanity monitoring and auditing techniques. Sanity monitoring is a fault tolerance technique in a distributed system. It detects and recovers from software faults. We discuss how to identify performance classes and fault types for processes, and how to locate and isolate faults. An audit program detects and recovers from data errors in communication systems such as telephone switches. It is adapted to distributed systems. We discuss data error detection and recovery methods for CDMA systems that also use OS primitives.
