Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Reliability estimation for redundant communication subsystem of fault-tolerant computer system Bogatyrev V.A. The article suggests reliability estimation technique for redundant communication subsystem of fault-tolerant computer system. The technique provides obtaining accurate outcomes when switches redundancy rate is less than four. When switches redundancy rate is more than four, approximate estimation with low error at upper and lower bounds is given.
