Disclosed is a data communication method, comprising: a first network management device acquiring identifier information about a second network device managed by a second network management device; according to the identifier information about the second network device and identifier information about a first network device managed thereby, establishing a corresponding relationship table between the identifier information about the second network device and the identifier information about the first network device; when the first network management device detects that the first network device fails to work normally, and the first network device is fault-free, according to the established corresponding relationship table, the first network management device acquiring the identifier information about the second network device corresponding to the first network device; and sending the identifier information about the second network device to the second network management device for performing fault processing. The present invention realizes that systems independent from each other can also coordinate with each other, a fault response speed and positioning accuracy are improved, and operation and maintenance costs are greatly reduced. |
