Abstract

A method and device for detecting a NETCONF session state are provided. According to an example of the method, detection of a NETCONF connection is caused by a change of an OpenFlow connection. In the case that a NETCONF session is established between a controller and a switching device, when detecting that an OpenFlow connection between the controller and the switching device changes in state, the controller sends a packet for obtaining session information of the NETCONF session to the switching device. The NETCONF session is determined to be abnormal if no session information is obtained within a preset time period; and the NETCONF session is determined to be normal if the session information is obtained within the preset time period.
