SD-WAN is a software-based network technology that delivers virtualized resources to wide area network connections over both ordinary broadband Internet and private links. Applying the concepts of software-defined networks to WANs, SD-WAN abstracts traffic management and monitoring from network hardware and applies them to individual applications.
SD-WAN can more effectively route all network traffic between data centers, branch offices, and the cloud than traditional WAN routers. SD-WAN dynamically uses multiple available connections to find the best delivery path for traffic across the entire network, eliminating jitter and dropped data packets, to deliver an optimal user experience in even the most far-flung remote offices.
SD-WAN provides a software abstraction to create a secure, reliable, transport-independent network overlay and decouples networking software services from the underlying hardware.
Many enterprises use WANs to connect branch offices to a variety of business-critical applications, including video-conferencing systems, ERP and CRM solutions, and more. SD-WAN enables companies to create a hybrid WAN architecture that combines multiple MPLS, mobile, and broadband connections into a single, logical, virtualized application-delivery path that dynamically responds to network conditions. And, unlike with a traditional WAN, companies can avoid upgrading network bandwidth to meet the demands of additional cloud services.
