AN ADAPTIVE DISTRIBUTED SYSTEM AND METHOD FOR FAULT TOLERANCE

摘要

An adaptive distributed system and method for fault tolerance is provided in a network (12) of at least three nodes (14) that are able to execute a distributed diagnosis algorithm in communication with the network. Each node has a device (16, 18) for testing whether a node is in a desired state or an undesired state and for determining which node to test. The method begins by using a tester node to test another node, determining whether the other node is in a desired or undesired state. If the tested node is in an undesired state, the testing is repeated on at least one further node until a node in a desired state is tested. If the tested node is in a desired state, an activation signal is provided to the tested node, causing it to become the tester node.
