Embodiment Construction

[0052] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0053] like figure 1 , a cloud computing-based SD-WAN network intelligent link selection method of the present invention is applied to a client device, and the method includes:

[0054] Step S10, establishing multiple communication links between the client device and multiple edge routers deployed in the cloud environment;

[0055] Step S20, detecting the network status of each communication link;

[0056] Step S30, evaluating the quality level of each link according to the detected network condition;

[0057] Step S40, according to the quality level of each link, determine the one with the highest quality level among the links as the main link, and the others as the backup links;

[0058] Step S50, setting the route of...

Abstract

The invention discloses an SD-WAN network intelligent link selection method based on cloud computing, and belongs to the technical field of networks. The method is applied to client equipment and comprises the following steps: S10, establishing a plurality of communication links between the client equipment and a plurality of edge routers deployed in a cloud environment; S20, detecting the networkcondition of each communication link; S30, evaluating the quality grade of each link according to the detected network condition; S40, according to the quality grade of each link, determining one link with the highest quality grade in each link as a main link and other links as standby links; and S50, setting the route of the client equipment according to the determined main link and standby links. According to the method, through periodic active detection, the network quality grade is evaluated in time, the relatively optimal link is intelligently selected for the network, and the actual usedemand of a user is fully considered.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a cloud computing-based SD-WAN network intelligent link selection method. Background technique [0002] Two basic components of a traditional enterprise network: (1) network equipment such as routers, switches, and VPN gateways; (2) enterprise-level line resources such as MPLS / MSTP. Although line resources can meet a certain SLA (Service Level Agreement, defined by delay, packet loss rate, jitter, bandwidth, etc.), in reality, the network environment is changing all the time and is very complicated. Even if there is a combination of good network equipment and high-quality line resources , nor can it guarantee that enterprise IT applications can get satisfactory results, such as: (1) network resources cannot be used reasonably, such as during peak hours of Internet access, network congestion, line resources are not enough, and expensive network dedicated lines are not...
