Embodiment Construction
[0040] The implementation of the technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0041] FIG. 1 is a structural diagram of a cluster system for implementing fault-tolerant functions in the present invention. in:
[0042] There are m processes running in a cluster system containing n computing nodes, and the computing node failures are all stopped by failure. When a node fails, other nodes can detect its failure immediately. A process running on a node can be described as a two-tuple: P=(pm, bk), where pm and bk represent the major version and minor version of the process, respectively. Since each process in the embodiment of the present invention contains only one corresponding copy, the fault-tolerant model only allows single-point failure. If more process copies are used, the model can be extended to multi-point failure. The fault-tolerant method of the present invention is completely ba...
