Segment Routing (SR) policy is a set of candidate SR paths consisting of one or more segment lists and necessary path attributes. It enables instantiation of an ordered list of segments with a specific intent for traffic steering. In-situ Flow Information Telemetry (IFIT) refers to network OAM applications that apply dataplane on- path telemetry techniques. This document defines extensions to PCEP to distribute SR policies carrying IFIT information. So that IFIT behavior can be enabled automatically when the SR policy is applied.
