What it shows

  • SLA probes monitor jitter, packet loss, and latency across links every second.
  • Voice (MOS > 4.0) routes via MPLS; bulk web traffic routes via cheap broadband.
  • Automatic sub-second failover prevents dropped Zoom calls during ISP brownouts.

The takeaway

SD-WAN applies real-time link telemetry to forward traffic based on application SLA requirements.
