What is SD-WAN?

    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: 

    • Transport independence
    • Application visibility
    • Path intelligence
    • Centralized management

    As the SD-WAN market changes, vendors continue to develop these capabilities as solution foundations.
