Abstract
Embodiments of the present invention provide a switch mode switching method, a device, and a system, so that routing and switching information in a hardware forwarding entry in the conventional switching mode is represented in a form of OpenFlow flow table. The method includes: receiving, by a switch, a mode switch request message that is sent by a controller and that is used to request the switch to switch from a conventional switching mode to an OpenFlow switching mode; freezing, by the switch, all routing and switching information tables of the switch in the conventional switching mode, and generating, according to routing and switching information in each routing and switching information table, an OpenFlow flow table corresponding to the routing and switching information table; and switching, by the switch, to the OpenFlow switching mode, and sending a mode switch response message to the controller.
