vEdge Tunnels - High Loss

[Oliquino_2009]

How do tunnels are built on SDWAN? How does it computes for jitter, loss and latency?

.. for how tunnels are built on SDWAN
and

for how loss, jitter etc is computed. (it is used in application aware routing w/ sla classification)

SD-WAN tunnels are built with IPSEC for dataplane and TLS/DTLS for the control plane.

BFD runs between edges to measure jitter, loss and latency
