Summary

This Recommendation describes the functional architecture of Transport MPLS (T-MPLS) layer networks using components of the MPLS network architecture described in ITU-T Rec. G.8110/Y.1370. The T-MPLS network functionality is described from a network-level viewpoint, taking into account T-MPLS network layering, definition of characteristic information, client/server associations, networking topology and layer network functionality. The functional architecture of the server networks used by the T-MPLS network is not within the scope of this Recommendation. Such architectures are described in other ITU-T Recommendations or IETF RFCs.
