With a total of three patents to her name, her work has had a substantial impact on improving network efficiency and reliability.

Latest Patents

Kaori Shimizu's latest patents include a path management control method, a path management control program, a path management controller, and a path management control system. The path management controller refers to resource information, including reservation statuses of working paths and advance reserved paths that are set in every link. This technology calculates a route for setting a new path and establishes this path within the calculated route. If the route for setting this new path cannot be obtained due to a shortage of residual bandwidth, the path management controller calculates an alternative route for another existing path used in the link of interest. Additionally, if there is no continuous bandwidth sufficient for setting the new path, the controller executes time slot rearrangement based on resource reservation information.

Another significant patent is the route switching method, which is designed for switching a route in a core network that accommodates service networks. This method utilizes a server that stores path information, including routes for both working and backup paths. The server calculates these routes in response to connection requests and can send the backup path information to the boundary node apparatus before a failure occurs in the core network. This allows for quick recovery by switching from the working path to the backup path when necessary.
