How do companies with a large number of nodes network?

A domestic group has a global business layout, with bases in the United States, Europe, Asia and China. Therefore, IT is necessary to arrange IT departments in each region, and IT headquarters will take the lead in strategic planning and design implementation, and introduce global related software and hardware systems to support the daily maintenance of R&D, design, marketing and production departments. In order to enhance operational efficiency and meet future demands, the global network architecture has been continuously optimized, and SD-WAN solutions have been continuously introduced.

In the past, it often took 6-8 months for customers to add a node overseas or apply for a dedicated line. Now, through the SD-WAN scheme, SD-WAN can be directly deployed on Internet lines to complete the connection, and then integrated with Internet lines for backup, or directly deployed to small offices through multiple Internet lines to quickly realize intranet network services, and the construction time is reduced by half compared with before.

Soon after SD-WAN went online, the office line was disconnected. At that time, SD-WAN immediately played the backup function, which made the whole network switch without induction and continued to provide network services.

Before and after the establishment of SD-WAN network, customers saved about 50% of the line cost.
