摘要： A stand alone Redundancy Management System (RMS) provides a cost-effective solution for managing redundant computer-based systems in order to achieve ultra-high system reliability, safety, fault tolerance, and mission success rate. The RMS includes a Cross Channel Data Link (CCDL) module and a Fault Tolerant Executive (FE) module. The CCDL module provides data communication for all channels, while the FTE module performs system functions such as synchronization, data voting, fault and error detection, isolation and recovery. System fault tolerance is achieved by detecting and masking erroneous data through data voting, and system integrity is ensured by a dynamically reconfigurable architecture that is capable of excluding faulty nodes from the system and re-admitting healthy nodes back into the system.
