Generalized Multi-Protocol Label Switching (GMPLS)
Generalized
Multi-Protocol Label Switching (GMPLS) is a protocol suite
extending MPLS to manage further classes of interfaces and switching
technologies other than packet interfaces and switching, such as
time-division multiplexing, layer-2 switching, wavelength switching
and fiber-switching.
Generalized MPLS
differs from traditional MPLS in that it extends support to multiple
types of switching such as TDM, wavelength and fiber (port)
switching. For instance, GMPLS is the de facto control plane of
wavelength switched optical network (WSON). The support for the
additional types of switching has driven GMPLS to extend certain
base functions of traditional MPLS and, in some cases, to add
functionality.
These changes and additions impact basic label-switched path (LSP)
properties: how labels are requested and communicated, the
unidirectional nature of LSPs, how errors are propagated, and
information provided for synchronizing the ingress and egress LSRs.
GMPLS is based on
Generalized Labels. The Generalized Label is a label that can
represent either
- a single fiber
in a bundle,
- a single
waveband within fiber,
- a single
wavelength within a waveband (or fiber), or
- 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.
GMPLS is composed of three main protocols:
- Resource
Reservation Protocol with Traffic Engineering extensions
(RSVP-TE) signaling protocol.
- Open Shortest
Path First with Traffic Engineering extensions (OSPF-TE) routing
protocol.
- Link Management
Protocol (LMP).
Wavelength Switched Optical Network with two established lightpaths.
