The embodiments of the invention provide a network abnormity notification method and apparatus. An Open Flow switch detects whether an Open Flow network is abnormal, and when it is detected that the Open Flow network is abnormal, the Open Flow exchange sends a first asynchronous message for describing abnormities occurring in the Open Flow network to a controller so as to enable the controller to process the abnormities occurring in the Open Flow network according to the first asynchronous message, such that network abnormities can be timely notified, the processing efficiency of the abnormities of the Open Flow network is improved, and the technical problems are solved that the abnormities occurring in the Open Flow network, caused by emergencies cannot be notified timely, the abnormities occurring in the Open Flow network cannot be processed timely, and accordingly the processing efficiency of the abnormities occurring in the Open Flow network is quite low in the prior art.
Description
technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and device for notifying a network abnormality. Background technique [0002] The modern large-scale network environment is very complex. Various abnormalities may occur during network transmission. The open source (OpenFlow) network support controller sends query requests to the OpenFlow switch periodically or according to the instructions of the administrator to obtain relevant information. The obtained relevant information detects whether the OpenFlow network is abnormal, and handles the abnormality when an abnormality occurs. [0003] However, the existing technology cannot timely notify the abnormalities of the OpenFlow network caused by emergencies, for example, network congestion due to excessive instantaneous traffic, etc., so that the abnormalities of the OpenFlow network cannot be processed in time, and the processing efficiency of the...
