Abstract

The invention provides a hot modification method for a flow table and configuration of a network controller. A software-defined network controller is provided, the software-defined network controlleris connected with at least one gateway, the software-defined network controller comprises an application layer and a control layer, the control layer is provided with at least one template, a plurality of applications are arranged in the application layer, and each application comprises at least one service; the hot modification method comprises the following steps that S1, the software-defined network controller determines an application corresponding to a service according to the service needing to be issued by a gateway; s2, an application is started, and a template corresponding to the service by the application is called; and S3, the application performs data filling on the called template to form a setting file, and the control layer issues the setting file to the corresponding gateway. The method has the beneficial effects that the development difficulty of the application in the application layer is reduced, and the development time is shortened, so that the online risk of theapplication is reduced, namely, the safe and rapid online of the application is realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for thermal modification of flow table and configuration of a network controller. Background technique [0002] Software Defined Network (SDN, Software Defined Network) is a new network innovation architecture. OpenFlow (an online communication protocol) is the core technology of software defined network, which can separate the control plane and data plane of network equipment. In this way, a flexible virtual network is created, thereby realizing flexible control of network traffic and making the network more intelligent. [0003] At present, the process of modifying the flow table and configuration issued by the gateway by the mainstream SDN controller will involve the modification of the SDN controller. Therefore, when the SDN controller version goes online, the SDN gateway must be migrated so that the SDN gateway is connected to At other controllers (if the mig...
