Abstract: A method and an apparatus for notifying a network abnormality are provided. An OpenFlow switch detects whether an abnormality occurs in an OpenFlow network. The OpenFlow switch sends a first asynchronous message for describing the abnormality occurring in the OpenFlow network to a controller when detecting an abnormality occurring in the OpenFlow network, so that the controller processes, according to the first asynchronous message, the abnormality occurring in the OpenFlow network. In this way, the abnormality in the network is notified in time, thereby improving efficiency in processing the abnormality in the OpenFlow network. A technical problem in the prior art that an abnormality occurring in an OpenFlow network and caused by an unexpected event cannot be notified in time, so that the abnormality occurring in the OpenFlow network cannot be processed in time and efficiency in processing the abnormality occurring in the OpenFlow network is relatively low is solved.

Abstract translation: 提供了一种用于通知网络异常的方法和装置。 OpenFlow开关检测OpenFlow网络是否发生异常。 当检测到OpenFlow网络中发生的异常时，OpenFlow交换机发送用于描述在OpenFlow网络中发生的异常的第一异步消息给控制器，使得控制器根据第一异步消息处理在OpenFlow网络中发生的异常 。 以此方式及时通知网络异常，提高处理OpenFlow网络异常的效率。 现有技术中的技术问题是，不能及时通知OpenFlow网络中发生的异常并且由于意外事件引起的异常，从而不能及时处理在OpenFlow网络中发生的异常并且处理在 OpenFlow网络相对较低被解决。
