Software-defined wide area network

Software-defined wide area network (SD-WAN) is a type of computer network that enables the bonding of multiple internet access resources – such as DSL, cable, cellular, or any other IP transport – to provide reliable high throughput data channels.

SD-WAN abstracts connectivity options – like multiprotocol label switching (MPLS), mobile, and broadband – to create a virtual enterprise-wide-area network (WAN).

An SD-WAN has a virtual WAN architecture and software-driven technology. A key element of a Software-defined wide area network is its centralized control, so that network connection, security mechanisms, policies, application flows, and general administration are separated from the associated hardware.

For security considerations, data communications between offices are typically transmitted via VPN and funneled through the main office facility. Read more..
