IDC transaction cross-domain decision-making method of remote active-active system

The invention relates to an IDC transaction cross-domain decision-making method of a remote active-active system, which manages and issues a cross-domain rule and cross-domain configuration by adding a configuration management center, and collects information about whether a gateway cluster request in each region is successfully transferred by adding a decision-making center; judging whether cross-domain is needed when the gateway in each region performs related interface request transfer by combining a cross-domain rule; and finally, comprehensively judging the cross-domain results of all gateways in each region, making a request transfer cross-domain decision of related interfaces in each region, and notifying all gateways in each region. According to the method, request switching and cross-domain decision making are decoupled, so that the gateway only carries out pure request switching, and the decision making center carries out complex cross-domain decision making; in the method provided by the invention,
