Problems solved by technology

However, if the behavior of the default flow entry is to discard all packets, it will cause a delay in user response time and thus affect user experience; if the behavior of the default flow entry is to report all user packets to the SDN controller , which may cause a large number of user packets to be sent to the SDN controller in an instant when the system starts, causing a large impact on the SDN controller

Embodiment Construction

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0022] see figure 1 , which is a schematic structural diagram of an embodiment of an SDN system to which the user policy-based SDN message processing method provided by the present invention is applicable. The SDN system 100 includes an SDN switch 110, an SDN controller 120, and a plurality of user equipment 130; wherein the plurality of user equipment 130 can be connected to the Internet 140 through the SDN switch 110, and the SDN controller 120 can also connected to the SDN switch 110. In the SDN system 100, the SDN controller 120 mainly perf...

Abstract

This application provides a method for processing SDN packets based on user policies. The method for processing SDN packets based on user policies includes: generating a default flow table according to a user policy configuration file, the default flow table including a plurality of flow entries respectively corresponding to different priorities; between the SDN device and the SDN controller Establish a message transmission channel between; according to the relevant flow entry of the default flow table, transmit the high-priority user message to the SDN controller through the message transmission channel, and transmit the low-priority user message to the SDN controller The text is discarded directly. The present application provides an SDN device and an SDN system adopting the above SDN packet processing method.

Description

technical field [0001] The present application mainly relates to communication technologies, and in particular, relates to a user policy-based SDN packet processing method, system and SDN equipment. Background technique [0002] Traditional computer networks lack a centralized control mechanism. Each network protocol needs to consider mechanisms such as network state coordination, network element discovery, and fault recovery, and it is very difficult to deploy new functions on the network. In response to the above problems, the industry proposes a new network architecture SDN (Software Defined Network, Software Defined Network), which mainly uses the OpenFlow (Open Flow) protocol mechanism to separate the control plane of network equipment from the data plane and realize centralized and flexible networks. Control greatly facilitates the maintenance of the network and the deployment of new functions, making the network more intelligent as a pipeline. [0003] Generally spea...
