SD-WAN Buying Guide from Tech Guidance

Network World defines SD-WAN as “combining multiple
physical WAN links into one logical network and providing traffic prioritization to accelerate application performance. Using network abstraction, SD-WAN improves the economics of branch connectivity by enabling organizations to leverage inexpensive circuits, such as the Internet, to address growing bandwidth requirements. SD-WAN is relatively easy to deploy and manage as it maps new services – application prioritization, security, management – on top of existing physical networks.”
