Latest Patents

Shibata's latest patents include a communication system and method that aim to improve network switching efficiency. One of his inventions involves a transmission-side switching device and a reception-side switching device. The objective is to provide a communication system that can perform network switching of multiple L2 networks with minimal communication disconnection time, without being limited by topology. The transmission-side accommodation switch duplicates frames from user devices and transfers them to various L2 networks. The reception-side accommodation switch selectively transfers frames to user devices, ensuring that only the appropriate frames are sent while discarding others during switching times.

Another notable patent focuses on a communication device and address learning method. This invention seeks to reduce bandwidth compression when a frame addressed to an original MAC address is received again after being overwritten. The communication device measures traffic amounts and holds MAC entry information, allowing for efficient management of MAC addresses and traffic data.
