摘要
Provided are a method and device for processing a Graceful Restart (GR) of an OpenFlow switch, and an OpenFlow controller. The method includes that: the OpenFlow switch is determined being in a GR state; and the state of the OpenFlow switch is marked as the GR state, wherein marking the state as the GR state includes: keeping a flow table and external connection of the OpenFlow switch before GR still valid, and prohibiting the flow table from being modified. Through the present disclosure, the problem in the related art that GR of an OpenFlow switch cannot be achieved is solved, thereby achieving the effect of effectively implementing the GR of the OpenFlow switch.
