What Is Managed SD WAN?

SD WAN is an acronym for software-defined wide area networking. Managed SD WAN refers to offering this approach to networking as a managed service.

SD WAN architecture defines traditional WAN routers and other physical network technologies through software definitions and simplifies the use of data transport standards such as MPLS, internet and cellular networks. It enables load sharing of traffic across multiple network connections, optimizing data routing and making transmission more efficient.

Because it is managed, the service provider performs the implementation of the software and hardware with the customer only paying the provider a fee to manage the network; this includes applications running on the network as well as its monitoring, and maintenance services.

The main benefit of SD WAN is that it reduces the costs of running WANs because it supplements or replaces dedicated private network links, usually implemented via MPLS, with regular broadband connectivity.
