Technological innovation "SD-WAN" that overturns the common sense of networks
SD-WAN technology is now attracting attention as a solution to such demands.
So what is SD-WAN? Simply put, it's a technology that identifies applications and controls WAN traffic based on user policy.
This is the same concept as SDN used in data centers, etc., and it is applied to WAN to realize the requirements of (1) centralized management, (2) separation of data and control, and (3) software control.
In addition, overlay technology is used to communicate with each component on the WAN.
To be more specific, in the conventional corporate network, it is necessary to set the CPE of each base individually, and on-site work and adjustment for that are issues, and security device operation and policy management are also required for security measures. Etc. tend to be complicated.
In such a situation, using SD-WAN makes it easier to deploy bases and manage various things, and at the same time, strengthens security measures.
