Abstract
A method of setting up an end-to end connection between two end-points in an optical network. A plurality of validated paths in the network are defined. Each validated path extends between a respective pair of wavelength termination points and has requisite physical resources to carry signal traffic between its pair of wavelength termination points. A graph of the network is generated. An edge of the graph corresponds with a respective validated path, and a vertex of the of the graph corresponds with at least one wavelength termination point. The graph is analyzed to compute an end-to-end path between two vertices respectively corresponding with end-points of the end-to-end connection, and the end-to-end connection set up using the computed path.
