Generalized Multi-Protocol Label Switching (GMPLS) [RFC3945] extends MPLS to handle multiple switching technologies: packet switching (PSC), Layer 2 switching (L2SC), Time-Division Multiplexing (TDM) Switching, wavelength switching (LSC) and fiber switching (FSC). A GMPLS switching type (PSC, TDM, etc.) describes the ability of a node to forward data of a particular data plane technology, and uniquely identifies a control plane LSP region. LSP regions are defined in [RFC4206]. A network comprised of multiple switching types (e.g., PSC and TDM) controlled by a single GMPLS control plane instance is called a Multi-Region Network (MRN).

Generalized MPLS (GMPLS) Protocol Extensions for Multi-Layer and Multi-Region Networks (MLN/MRN)
There are specific requirements for the support of networks comprising Label Switching Routers (LSRs) participating in different data plane switching layers controlled by a single Generalized Multi- Protocol Label Switching (GMPLS) control plane instance, referred to as GMPLS Multi-Layer Networks / Multi-Region Networks (MLN/MRN).
This document defines extensions to GMPLS routing and signaling protocols so as to support the operation of GMPLS Multi-Layer / Multi-Region Networks. It covers the elements of a single GMPLS control plane instance controlling multiple Label Switched Path (LSP) regions or layers within a single Traffic Engineering (TE) domain.
