Embodiment Construction
[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] Therefore, it would be advantageous to provide a method to enable an SDN system to support multiple tunneling technologies without complicating the implementation of the SDN switch. It would also be advantageous to enable an SDN system to support new tunneling technologies not yet supported by conventional technologies without the need to update SDN sw...

The present invention provides a method for transmitting messages in a tunnel through a software-defined network (SDN), a method for intelligently controlling message flow through an SDN network, and a system. The method for transmitting a message in a tunnel through an SDN includes: sending the programmable instruction from a processor executing an application program including a programmable instruction to an SDN controller, wherein the programmable instruction includes information on processing the message so that according to The tunneling protocol performs a primitive operation through the tunnel; the first SDN controller configures a flow table according to the programmable instruction; and the SDN switch processes and distributes the message according to the flow table. The method can enable the system to support multiple tunneling technologies without complicating the implementation of the SDN switch, and can enable the system to support new tunneling technologies without updating the SDN switch, Therefore, the complexity of the SDN switch is reduced.
Description
[0001] The present invention claims the prior application priority of the US Provisional Application No. 61862400 filed with the US Patent and Trademark Office on August 5, 2013, entitled "SOFTWARE DEFINED NETWORK BASED GENERIC TUNNELING", The content of this prior application is incorporated by reference into this text as if reproduced in its entirety. technical field [0002] The embodiment of the present invention relates to the communication field, and in particular to a method for transmitting packets in a tunnel through a software-defined network, a method for intelligently controlling packet flow through an SDN network, and a method for transmitting packets through tunnels used in SDN system. Background technique [0003] Traditional software-defined networking (SDN) technologies, such as the Openflow protocol used to connect SDN controllers and SDN switches, can only provide limited support to selected tunneling technologies or protocols, such as GRE, MPLS, VLAN.
