Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses. [1]
In telecommunications, Multiprotocol Label Switching - Transport Profile (MPLS-TP) is a variant of the MPLS protocol that is used in packet switched data networks. MPLS-TP is the product of a joint Internet Engineering Task Force (IETF) / International Telecommunication Union Telecommunication Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and ...
Generalized Multi-Protocol Label Switching (GMPLS) [1] 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.

Multi-Protocol Label Switching (MPLS) [6] [7] architecture is described in the RFC-3031. It is a packet-based network technology that provides a framework for recovery through the creation of point to point paths called Label Switched Paths (LSP). These LSPs creation are between a head-end and a tail-end label switch router (LSR).
GMPLS consist of several protocols, including routing protocols (OSPF-TE or ISIS-TE), link management protocols (LMP [1]), and a reservation/label distribution protocol . The reservation/label distribution protocol CR-LDP has now been deprecated by the IETF in RFC 3468 [2] (February 2003) and IETF GMPLS working group decided to focus purely on ...
The control plane is implemented on a separate network and typically employs one network controller for each node in the data plane, as shown in the figure. The Generalized Multi-Protocol Label Switching (GMPLS) protocol suite, the de facto standard control plane for WSONs proposed by the IETF, is composed of three protocols. [2]
Label switching is a technique of network relaying to overcome the problems perceived by traditional IP-table switching (also known as traditional layer 3 hop-by-hop routing) [1]. Here, the switching of network packets occurs at a lower level , namely the data link layer rather than the traditional network layer .
