Embodiment Construction
[0036] In order to realize the fault diagnosis of the SDN network control plane, the present invention needs to obtain accurate visibility when the SDN control plane system is running. For the internal and external events and messages transmitted from the data plane and application plane, the SDN controller will generate a series of For procedure call and processing process, the design of the present invention expresses the processing flow inside the control plane by defining the behavior model of the calling system. When an exception occurs, the relevant system behavior model will reflect the relevant event that triggered the exception and the key call process information, which can be used for fault identification, diagnosis and further root cause location.
[0037] The framework of the present invention is as figure 1 As shown, two environments are involved. On the one hand, deploy the data acquisition module in the control plane in the actual production environment to mon...
