SD-WAN involves managing WAN branch routers from a central controller, or creating the “brains” of the network, so that potentially thousands of routers can be managed from one place.
The main benefit of SD-WAN is that the network is easily managed from a central controller. Network administrators can build policies and seamlessly push them to every device at once, greatly simplifying IT management.
In addition to simplified management, SD-WAN can run over any type of network (such as broadband, fiber, LTE), through any type of service provider connection (Internet, MPLS).
There are four core features of SD-WAN:
As the SD-WAN market changes, vendors continue to develop these capabilities as solution foundations.
