SD-WAN Insights

What is SD-WAN?

SD-WAN (Software-Defined Wide Area Network) is a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including MPLS, broadband internet, and cellular – to securely connect users to applications. SD-WAN uses centralized control and management to intelligently direct traffic across the WAN, increasing application performance, lowering costs, and improving network agility.
