Abstract:
   Service Function Chain (SFC) defines an ordered set of service
   functions (SFs) to be applied to packets and/or frames and/or flows
   selected due to classification.  SFC Operation, Administration and
   Maintenance can monitor the continuity of the SFC, i.e., that all SFC
   elements are reachable to each other in the downstream direction.
   But SFC OAM must support verification that the order of traversing
   these SFs corresponds to the state defined by the SFC control plane
   or orchestrator, the metric referred to in this document as the path
   consistency of the SFC.  This document defines a new SFC active OAM
   method to support SFC consistency check, i.e., verification that all
   elements of the given SFC are being traversed in the expected order.
