What is SD WAN? (Software-Defined Wide Area Network)

SD-WAN stands for Software-Defined Wide Area Network. It is a network technology that uses software to control and manage the routing of network traffic across a business network. Traditional WANs typically rely on expensive proprietary hardware, which can be difficult to configure and manage, particularly for large and geographically distributed networks.

SD-WAN technology, on the other hand, enables the use of more cost-effective, commercially available Internet connections, while still providing the necessary security and quality of service for enterprise applications. SD-WAN provides a centralized control panel to manage the routing of traffic, which allows administrators to prioritize different types of traffic (e.g. VoIP, video conferencing, web traffic, etc.) and to create policies for network traffic management.

In summary, SD-WAN is a software-based approach to network management that provides greater flexibility, scalability, and control over enterprise networks, and can help organizations reduce costs and improve network performance.
