Abstract
Embodiments of the disclosure provide a method for packet tunneling through a software defined network (SDN), a method of intelligently controlling flow of a packet through an SDN network, and a system. The method for packet tunneling through an SDN includes: sending programmable instructions to an SDN controller from a processor executing an application program that includes the programmable instructions; wherein the programmable instruction comprises primitive operations regarding processing a packet for tunneling in accordance with a tunneling protocol; configuring a flow table by the first SDN controller in accordance with the programmable instructions; and processing and distributing the packet in accordance with the flow table by the SDN switch. The method may enable a system support multiple tunneling technologies without complicating the implementation of the SDN switch, and enable the system support new tunneling technologies without the need for updating the SDN switch, thereby reducing complexity of the SDN switch.
