Title: PROCESSING METHOD AND DEVICE FOR GRACEFUL RESTART OF OPEN FLOW SWITCH, AND OPEN FLOW CONTROLLER
Abstract:
Provided are a processing method and device for the graceful restart of an open flow (OpenFlow) switch, and an OpenFlow controller. The method comprises: determining that a state of an OpenFlow switch is a graceful restart state; and marking the state of the OpenFlow switch as a graceful restart state, wherein the step of marking the state as a graceful restart state comprises: keeping a flow table and an external connection of the OpenFlow switch before graceful restart still valid, and prohibiting making modifications to the flow table. By means of the present invention, the problem existing in the related art that the graceful restart of an OpenFlow switch cannot be realized is solved, thus achieving the effect of effectively realizing the graceful restart of the OpenFlow switch.
