Abstract: PROBLEM TO BE SOLVED: To provide a method for continuing node operation in a protocol based on quorum. SOLUTION: This method wherein a group comprising especially plural nodes includes only two nodes is especially useful in the state where communication to one node is damaged. A means for adding, to each node, an additional state instruction for showing whether a single node quorum operation is enabled or not is provided. A means for dispatching one node as a first node, and dispatching the other node as a second node for the purpose of time-out response is provided.
