SD-WAN
SD-WAN or Software Defined Wide Area Network is the next level of virtualization. It enhances or even replaces traditional branch routers with virtualization appliances that can control application level policies and offer a network overlay. Less expensive consumer-grade internet links can act more like a dedicated redundant circuit. This simplifies the setup process for branch personnel. The SD-WAN Edge is a physical or virtual network function that is placed at an organization’s branch/regional/central office site, data center, and in public or private cloud platforms.
