In particular, GMPLS offers the additional support for TDM, lambda, and fiber (port) switching''<ref>E. Mannie, "Generalized Multi-Protocol Label Switching (GMPLS) architecture", RFC 3945, Oct. 2004, IETF.</ref> ==How GMPLS works== GMPLS is based on Generalized Labels. The Generalized Label is a label that can represent either (a) a single fiber in a bundle, (b) a single waveband within fiber, (c) a single wavelength within a waveband (or fiber), or (d) a set of time-slots within a wavelength (or fiber). The Generalized Label can also carry a label that represents a generic MPLS label, a Frame Relay label, or an ATM label. ==References==
