Problems solved by technology

The sending of a large number of flow entries containing information between flow tables not only brings a heavy signaling burden on the interface connecting the OpenFlow switch and the OpenFlow controller, but also consumes a large amount of resources in the OpenFlow switch to store and process the flow table. The flow entry of the inter-information, thereby reducing the efficiency of the OpenFlow switch in processing data packets

Abstract

Embodiments of the present invention provide a method, controller, switch, and system for information transfer between OpenFlow flow tables, which relate to the technical field of wireless communication. The method includes: generating a flow entry, the flow entry includes indication information, and the indication information It is used to indicate the method of obtaining delivery information; wherein, the delivery information is the information to be delivered to the lower-level flow table; the flow entry is sent to the OpenFlow switch, so that the OpenFlow switch obtains the delivery information for the lower-level flow table according to the instruction information. The present invention generates a flow entry including indication information, and the indication information is used to indicate the method of obtaining transfer information; wherein, the transfer information is information that needs to be transferred to the lower-level flow table; the flow entry is sent to the OpenFlow switch, so that the open The flow switch obtains transfer information for the lower-level flow table according to the indication information, which reduces the number of flow table entries, thereby reducing the resources used for storing and processing flow table entries, and improving the efficiency of processing data packets.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method, a controller, a switch and a system for transmitting information between OpenFlow flow tables. Background technique [0002] With the development of wireless communication technologies, SDN (Software Defined Networking, software-defined network) has gradually become the development direction of mobile networks due to its advantages such as customizable network capabilities. The method of SDN processing data packets is as follows: the OpenFlow controller controls the OpenFlow switch to process data packets through the pipeline composed of flow tables at all levels through the flow entries of the flow tables at all levels in the OpenFlow switch. Wherein, each flow entry of any level of flow table describes a processing logic of the level of flow table processing data packets. When a data packet is processed through the flow table, if the information betwee...
