SD-WAN creates an overlay on top of your existing network and combines traditional transport connections with inexpensive broadband. Then SD-WAN dynamically and intelligently routes network traffic like voice, video, data, and cloud applications wherever it is needed across less expensive routes. This automated process improves overall network performance and simplified remote network management and control.

In an SD-WAN environment, implementation of changes or updates is done automatically so that users are completely unaware of the impact on their application usage. Network issues are automatically corrected based on quality metrics with little to no performance degradation versus in a traditional WAN environment.
