SDWAN
Branch or remote ofice network architectures, including wide-area networks (WANs), have barely changed since the 1990s. The requirements for branch connectivity have changed signiicantly in this time, however. The most common approach for nodes on a WAN have been to connect through a combination of MPLS circuits or broadband / IPSec. While not perfect, this has worked for businesses for many years. Today, the demands on wide area network bandwidth are seeing drastic increases as network trafic volumes are pushed by a variety of workloads including mobile, video, cloud storage/ collaboration and other high bandwidth applications. Options for dealing with this problem include adding more capacity to the existing WAN circuit or introducing an Internet connection to the branch WAN architecture.
