MPLS-TP is subset of MPLS. It uses the same data plane as used by MPLS (Defined in RFC 3031 and RFC 3032). MPLS-TP has four major areas:-
1. Data Plane
2. Control Plane
3. O&M
4. Survivability
MPLS-TP has no control plane, the reason for this was that the recovery. If the dynamic control plane is used, in that case the convergence would depend on the dynamic protocol and providers cannot leverage the <50 ms failover time in that case. It uses the same QoS diffserv model except uniform model as used in MPLS.
