It was intended specifically as a connection-oriented packet-switched (co-ps) application offering a simpler implementation by removing MPLS features that are not relevant to co-ps applications and adding mechanisms that provide support of critical transport functionality.
Service providers have already developed management processes and work procedures based on these principles for use in networks that use those other technologies.
In this way T-MPLS was intended to provide a reliable packet-based technology that is familiar and also aligned with circuit-based transport networking; it supports current organizational processes and large-scale work procedures.
T-MPLS is a low cost Layer 2 technology that provides QoS, end-to-end OA&M and protection switching.
These Recommendations will be superseded (i.e., replaced) by new revisions that apply to MPLS-TP and reference the joint work being undertaken by the ITU-T and IETF.
