What is a software-defined wide area network (SD-WAN)?
SD-WAN is a software-based network technology that provides virtualized resources to wide area network connections over traditional broadband Internet and private links. SD-WAN applies the concept of software-defined networks to WANs, virtualizing traffic management and monitoring in network hardware and applying them to individual applications.
SD-WAN can more efficiently route all network traffic between data centers , branch offices and clouds compared to traditional WAN routers . SD-WAN dynamically uses multiple available connections to find the best path to deliver traffic across the entire network, eliminating jitter and preventing data packet loss, providing an optimal user experience to remote branch offices farthest away. .
