What is SD-WAN and how does it work?
What is SD-WAN?
Software Defined Wide Area Network, also known as “SD-WAN” is a software defined networking (SDN) approach that elevates network traffic management away from hardware and premise, to next generation software in the cloud for enhanced agility, control and visibility.
How does it work?
SD-WAN uses a centralized control function incorporating user defined application and routing policies, to provide highly secure, dynamic, application-aware network traffic management.
This level of control allows for optimal delivery paths across any combination of network transport type, providing flexible deployment options and improved total cost of ownership.
