Top 3 Challenges for SD-WAN Performance

Image
In a Software-Defined Wide Area Network (SD-WAN), a branch router uses two or more network connections to dynamically route traffic over one another based on its profile. For example, real-time Voice-over-IP (VoIP) traffic is sent through a low latency MPLS circuit, while high bandwidth applications that don’t require low latency are routed over a broadband Internet connection. Another benefit of SD-WAN routers is that traffic is dynamically distributed between links, on a per-packet basis, based on links’ congestion, latency, and loss.
