The invention is a resource coordinating method based on WWW service, a WWW service coordinating technique, specially relating to a resource allocation system (such as e-commerce service system or network application) lock and livelock preventing method, able to avoid lock and livelock in the resource allocating process, thus raising resource utilization ratio. And it has high flexibility and does not need to exchange global or neighbor resource request information between coordinators of different applications, avoiding the communication caused by this. And resource allocation gives consideration to spare resource allocation solution. If resources are unable to meet the requirements of the current target state, it can assure reaching the spare target in the current resource possessing state as soon as possible, thus raising resource allocating speed. |
