Verification of Coordinated Exception Handling

Lookup NU author(s): Professor Alexander RomanovskyORCiD



An important challenge faced by the developers of fault tolerant distributed systems is to build fault tolerance mechanisms that are reliable. To achieve the desired levels of reliability, the development of mechanisms for detecting and handling errors should be rigorous or formal. In this paper, we present an approach to modeling and verifying fault-tolerant distributed systems that use exception handling as the main fault tolerance mechanism. The proposed approach is based on a formal model for specifying the structure of a system in terms of cooperating participants that handle exceptions in a coordinated manner. We use a medical control system as a case study to validate the proposed approach.
