Software-defined wide area networking (SD-WAN) doesn’t need to be a mystery. In essence, it’s technology that simplifies the operation and management of the many network connections between sites in an organization.SD-WAN lets you control how traffic is directed and prioritized across multiple uplinks, and enables your network to immediately and intelligently adapt to changing performance conditions — ensuring latency-sensitive traffic like VoIP or point-of-sale services have the throughput and optimization they need.
