Software-Defined Networking in a Wide Area Network (SD-WAN), is a new approach to support branch office connectivity in a simplified and cost-effective manner. It is the ability to use multiple ISP egress links to provide continuity across a specific path, whether that’s an SD-WAN that you define internal to your own perimeter network, or what you're also connecting to internet resources – like SalesForce, PeopleSoft, Cloud, and SaaS applications.
