HANDLING ERRORS IN AN ERROR-TOLERANT DISTRIBUTED COMPUTER SYSTEM

摘要

The invention relates to a method for handling errors in an error-tolerant distributed computer system and such a system, with a number of nodal computers (K1...K4), connected by means of communication channels (c11...c42) with access to the channels by means of a cyclical time slice method. Messages emanating from nodal computers (K1...K4) are checked by independently formed guardians (GUA), which either convert a message suffering from an SOS (Slightly Off Specification) error into a correct message or convert the same into a message which is clearly recognisable as incorrect by all nodal computers.
