Abstract

A flow table management method, device and system. A flow table management method, comprising: a software-defined network controller generates a first flow entry, wherein a first field set in the first flow entry carries an index of an actual value of the first field set, and the first field set includes N fields; the software-defined network controller sends an OpenFlow protocol message to the OpenFlow switching device, and the OpenFlow protocol message carries the first flow entry. The technical solution of the embodiment of the present invention is beneficial to reduce the data volume of the flow entry sent by the SDN Controller to the OpenFlow Switch, thereby reducing the control channel overhead, thereby reducing the risk of control channel congestion, and reducing the impact of the flow entry on the SDN Controller and the OpenFlow Switch. Network processing resource usage.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a flow table management method, related equipment and a communication system. Background technique [0002] OpenFlow (OpenFlow) technology was first proposed by Stanford University, aiming to solve the current network problems based on the technical conditions of Transmission Control Protocol / Internet Protocol (TCP / IP, Transmission Control Protocol / Internet Protocol) with innovative network interconnection concepts. Various bottleneck problems arising from new business. [0003] Among them, the core idea of ​​the OpenFlow technology is mainly to transform the packet forwarding process that was originally completely controlled by the switching device (switching device can be a switch, router, etc.) Defined Network) controller (SDN Controller) collaboratively complete. [0004] The SDN Controller can issue a flow entry to the OpenFlow Switch to indicate the packet f...
