This Recommendation provides the functional components, based on [ITU-T G.805], that are necessary to describe the deployment of Multi-Protocol Label Switching Transport Profile (MPLS-TP) in a transport network. This model allows MPLS-TP to be modelled in a way that is consistent with the description of other transport technologies defined by ITU-T, (e.g., the synchronous digital hierarchy (SDH), the optical transport network (OTN), etc.).
