Segment Routing Traffic Engineering Policy (SR-TE) aka SR Policy makes use of Segment Routing (SR) to allow a headend to steer traffic along any path without maintaining per flow state in every node. A headend steers traffic into an “SR Policy”. Class Based Forwarding (CBF) for SR-TE is a means for steering IP traffic into an SR Policy based on the ingress DSCP values. This mechanism is described in the section on Per-Flow Steering in the Segment Routing Policy Architecture Internet draft.

Class Based Forwarding (CBF) is a means for steering IP traffic into colored tunnels based on the ingress DSCP values. CBF may be used with SR-TE Policy, RSVP-TE or Flex-Algo colored tunnels.

Bidirectional Forwarding Detection (BFD) is a protocol that provides low-overhead, short-duration detection of failures of arbitrary paths between two systems.
