Wide Area Networks (WANs) are increasingly difficult to manage. The average enterprise network has assets in diverse locations, increasing scale and numerous unique devices. To add to that, most leverage many different transport options including MPLS, Carrier Ethernet, Frame-Relay, legacy T1/E1 circuits and cellular connections.
Enterprises are looking at new technologies such as Software Defined WAN (SD-WAN) to achieve agility and cost savings. As enterprises leverage this approach, they must choose between testing new vendors with proprietary solutions requiring new hardware, or increasing and extending the life of their existing infrastructure while turning embedded feature sets on.
