Problems solved by technology
[0004] However, the failure of the connection between the switching device and the SDN controller may be caused by the failure of the SDN controller, or the failure of the link between the switching device and the SDN controller.
Based on this, the method of determining whether the SDN controller is faulty by the switching device through its connection status with the SDN controller is inaccurate, which will cause unreasonable fault handling by the switching device

The embodiment of the present invention provides a method and device for determining a failure of a software-defined network controller, which is applied to a failure server. The method includes: receiving a connection status sent by a switching device; The connection status of the device; when receiving the first connection status indicated as a connection failure for the first time, determine the connection status of all other switching devices except the first switching device sending the first connection status to the SDN controller; When the connection states of all other switching devices and the SDN controller are indicated as abnormal, it is determined that the SDN controller is faulty. By applying the technical solutions provided by the embodiments of the present invention, the accuracy of determining whether the SDN controller is faulty is improved.
Description
technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for determining faults of software-defined network controllers. Background technique [0002] SDN (Software Defined Network, software defined network) is a new type of network architecture, which separates the control plane and the forwarding plane, and realizes flexible control of network traffic. In SDN, the SDN controller is a key device of the SDN, which is responsible for delivering forwarding rules to the switching device, and the switching device forwards traffic according to the received forwarding rules. [0003] For the switching device, the switching device determines whether the SDN controller is faulty through the connection status between the switching device and the SDN controller, and handles the fault to forward traffic. Specifically, if the switching device is successfully connected to the SDN controller, it is determined th...
