Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application. The relevant directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship between the components in a certain posture (as shown in the drawings). Sports conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0038] As mentioned in the background art, the routing selection method of the SDN network in the prior ar...

Abstract

The invention discloses an SDN network-based multi-QoS load balancing routing method, a storage medium and a terminal. The method comprises the steps: determining a plurality of service quality impactfactors of the SDN network, and calculating the weight corresponding to each service quality impact factor through employing an AHP analytic hierarchy process; calculating the weight of each link inthe SDN network based on the calculated weight of each service quality influence factor; and selecting a corresponding optimal load balancing route for the arrived data flow based on the calculated weight of each link in the SDN network. According to the scheme, the route meeting the multi-user service quality requirement can be selected in the SDN network. The service quality is improved, and thesatisfaction degree of users is improved.

Description

technical field [0001] The invention belongs to the technical field of software-defined networks, and in particular relates to a multi-QoS load balancing routing method based on an SDN network, a storage medium and a terminal. Background technique [0002] Software Defined Network (Software Define Network, SDN) is a new type of network architecture proposed by Stanford University in the United States. SDN technology is a method that breaks the traditional network organization and application method, and has logical centralization, separation of control and forwarding, open interface and programmable A brand-new network architecture with such characteristics. [0003] At present, the control plane of software-defined networks is mostly composed of single-instance controllers, and its performance, reliability and other indicators are difficult to meet the requirements of large-scale deployment. In addition, in the face of different network scenarios, the requirements for the ...
