WAVELENGTH PATH MANAGEMENT APPLICATIONS FOR RECONFIGURABLE ARRAYED WAVEGUIDE GRATING-STAR NETWORK

We have proposed an arrayed waveguide grating router (AWGR) network with a loopback function by optical switches (OSWs) that are located on optical nodes that allow the arbitrarily reconfigured wavelength path architecture. In order to easily manage the architecture, we have also proposed the method expressed network topology so that it could also calculate network information based on topologies and be helpful for a network controller that needed topology information. However, since the proposed method outputs the wavelength path from the OSW state, it is impossible to calculate the required OSW states from the information between the nodes where the wavelength path is multiplexed. If we employ the inverse matrix calculation to know the required OSW states, we must know all matrices except OSW state in advance, which is unrealistic. Thus, in this study, our proposed method simulates the case that the target network has only the required path and, calculates wavelength path routes and required OSW states. In addition, from the network management perspective, we need an interface easy for network administrators to manage, but previous proposals have only considered basic calculation methods. In this study, we develop an application with a graphical user interface for network administrators, which can show the required wavelength path and OSW states when the information between the nodes where the wavelength paths are multiplexed is inputted into the application.
