Interworking Requirements to Support Operation of MPLS-TE over GMPLS Networks", RFC 5146

This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Operation of a Multiprotocol Label Switching (MPLS) traffic engineering (TE) network as a client network to a Generalized MPLS (GMPLS) network has enhanced operational capabilities compared to those provided by a coexistent protocol model (i.e., operation of MPLS-TE over an independently managed transport layer). The GMPLS network may be a packet or a non-packet network, and may itself be a multi-layer network supporting both packet and non-packet technologies. An MPLS-TE Label Switched Path (LSP) originates and terminates on an MPLS Label Switching Router (LSR). The GMPLS network provides transparent transport for the end-to-end MPLS-TE LSP
