Abstract: The application of a fault tolerance technique to the intelligent agent technology to create a highly-reliable distributed computing system. The present invention relates to the merger of software fault tolerance techniques to cooperative intelligent agents to provide highly reliable coordination of interactions between computer systems, even when data is corrupt, when available information is incomplete, or when synchronization of the computer systems is imperfect. Agents engaged in an interaction exchange information. Received information is acceptance tested to determine if the information indicates the occurrence of a fault. If the information is outside a range of expected values, or otherwise does not take the form of expected information, a fault is indicated. A fault tolerance technique is employed to overcome the fault. One such technique is the retry block software fault technique. Re-expression and re-transmission of the information may be requested.
