Abstract(in Japanese) (See Japanese page)
Abstract(in English) We propose a hierarchical network configuration architecture, which minimizes the repairing time from a disruption state to a sub-optimal state (e.g., 80% traffic recovery), by recomposing wavelength and/or MPLS paths on 10,000 nodes network. When a single platform configures 10,000 nodes, repairing time increases because of limit of parallel configurations, and computation algorithm, whose computation time increases with the cube of the number of nodes. By dividing network to multiple domains and using multiple platforms for configuration, we realize parallel configuration, and can drastically reduce the configuration time. For the computation, which cannot be divided for parallel computation such as multi-domain path computation, we compress the amount of network information and reduce the computation time by optimizing the function deployment on each platform. We implement above platforms, and evaluate the total repairing time, which consists of wavelength/MPLS path configuration and algorithm computation.
