Abstract
In an OPENFLOW communication method an action that needs to be transferred and sent by the service gateway is received, one appropriate virtual switch is selected according to the action and a network topology, a flow table is delivered to the service gateway and the virtual switch, and a first data channel is established between the service gateway and the virtual switch to forward a packet, a flow table including an extended action is delivered to the virtual switch so as to execute a related extended action on the packet, the packet is obtained after the virtual switch executes the related extended action is sent to a destination server. Accordingly, some data processing services are transferred to a virtual server when a processing capability of a service gateway is insufficient such that the virtual service implements load balance among network elements in a system.
