Automated Congestion Avoidance with an SDN Controller
2021-11-09, 14:50–15:00 (Europe/Berlin), Main Stage

In this presentation, I will discuss how an SDN Controller that receives streaming telemetry from the network can automatically tune the paths of SR-TE or RSVP-TE LSPs in order to avoid congestion occurring. Contrary to popular belief, it is not necessary to fully mesh all of the edge nodes with TE LSPs to achieve this.
