A Novel Optical Control Plane for Switching an Electro-Optical Hybrid Node in Translucent WDM Optical Networks
In a translucent network scenario, development of an Optical Control Plane (OCP) that is aware of the location and number of available regenerators and All-Optical Wavelength Converters (AOWCs) is of paramount importance. However, current Generalized MultiProtocol Label Switching (GMPLS) protocol suite does not consider the distribution of regenerator and AOWC availability information to all the network nodes. In this paper, the authors propose a novel Optical Control Plane (OCP) architecture that; disseminates information about network components (i.e. regenerators and AOWCs) to all the network nodes and evaluates candidate routes which use fewest amounts of network components.
