Functional benefits that SD-WAN can provide

Advancement of SD-WAN deployment

On the other hand, companies with multi-site interconnection needs rarely communicate with operators about system data grading. First, because existing systems and data grading will involve the transformation of existing applications, and existing enterprise private line bandwidth prices are sufficient to support Its one-size-fits-all bearing method; second, data grading often involves internal data management, and these problems are often not solved by IT operations personnel. Therefore, it can be seen that most enterprises in the real world do not imagine the enthusiasm for the SD-WAN “multi-path selection of sub-service levels”. The main reason is that enterprises cannot truly distinguish the application data levels.

At present, most SD-WAN high-quality network solutions are actually an overlay solution carried on the original WAN network. By superimposing the network “tunnel” and utilizing the characteristics of high-quality network light load, the network quality is partially improved. Not fully meeting customer expectations for SD-WAN. The deployment of SD-WAN still has a long way to go.

Next stop: SD-Branch

With the advancement of SD-WAN deployment, the industry has set its sights on the next evolutionary trend of SD-WAN, the software-defined branch (SD-Branch). As the name suggests, SD-Branch provides software-efficient, network-based management, and cloud-based management to provide efficient bandwidth utilization, better application service quality, and greater security. A number of advantages within. It is reported that many corporate websites have 6 to 10 devices to manage the network, including routers, wireless access points, firewalls, unified threat management systems and WAN optimization. Since customers want to merge these multiple branches into one system, SD -Branch’s appearance is naturally also reasonable.

In SD-Branch, routing, firewall, and WAN optimization are virtualized as a NaaS model for the cloud to replace expensive hardware, management is automated, and services can be easily adapted to changes in business needs. Currently, SD-Branch is being designed to replace dedicated hardware with virtualized software. Centralized management allows centralized IT staff to effectively exclude, secure, and upgrade remote branches of the network.
