Research on Optical Communication Network Based on GMPLS Technology

The huge demand for communication network has tend to make topologies of optical networks based on wavelength division multiplexing (WDM) complex. This article proposes a new approach for optical communication network with GMPLS technology in WDM networks. GMPLS grew out of vanilla MPLS, a packet-switching technology designed to improve the efficiency of data networks. A flavor of MPLS, known as MPLS-TE, provided for provisioning of end-to-end connections using signaling with constraint-based routing. It was a natural move to generalize and extend it to cover circuit- oriented optical switching technologies such as time- and wave-division multiplexing (TDM and WDM). With the help of GMPLS, optical communication network will be more efficient.
