What is SD-WAN?
Software-defined wide area networking (SD-WAN) is a distributed networking approach that provides organizations a sustainable alternative to high latency hub-and-spoke network topologies.
How SD-WAN supports network performance
Legacy hub-and-spoke networks backhaul branch office traffic to a centralized data center directly through MLPS dedicated lines, with remote and home-based workers connecting through VPN. Organizations of the past favored this model for its centralized management and security, which worked reasonably well in an era when all applications were installed on the desktop or data center servers.
But the rapid proliferation of cloud applications and services overload MPLS circuits, as every little action a remote user takes in a cloud application must send traffic:
First to the data center,
Then out to the cloud
Back through the data center again, and…
