RFC 8372 describes the requirement for introducing flow identities within the MPLS architecture. This document describes a method of accomplishing this by using a technique called Synonymous Flow Labels in which labels which mimic the behaviour of other labels provide the identification service. These identifiers can be used to trigger per-flow operations on the on the packet at the receiving label switching router.
