Method and apparatus for notifying network abnormality

A method for notifying a network abnormality, the method comprising:

• receiving, by a controller, a first asynchronous message sent by an OpenFlow switch, wherein the first asynchronous message is generated and sent when the OpenFlow switch detects an abnormality occurring in an OpenFlow network, and the first asynchronous message is used to describe the abnormality occurring in the OpenFlow network;
• and
• processing, by the controller and according to the first asynchronous message, the abnormality occurring in the OpenFlow network.

An apparatus for notifying a network abnormality, the apparatus comprising:

• a detecting module, configured to detect whether an abnormality occurs in an OpenFlow network;
• and
• a sending module, configured to send a first asynchronous message to a controller when it is detected that an abnormality occurs in the OpenFlow network, so that the controller processes, according to the first asynchronous message, the abnormality occurring in the OpenFlow network, wherein the first asynchronous message is used to describe the abnormality occurring in the OpenFlow network.
