Title: Takafumi Hamano: Innovator in Communication Systems

Introduction

Takafumi Hamano is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of communication systems, holding a total of 6 patents. His innovative work focuses on enhancing network control and optimizing optical transport systems.

Latest Patents

One of his latest patents is a control apparatus, network control method, and program. This control device manages a communication system where a network device and a virtual network device on a cloud communicate through a tunnel. The device includes a calculation unit that predicts the number of future setting entries in the virtual network device. It also features an autoscale execution unit that adjusts the scale of the virtual network device based on a comparison between the predicted value and a threshold. Additionally, a control unit performs routing control between an application and the virtual network device in a cloud service platform.

Another notable patent is related to an optical transport system and resource optimization method. In this system, a transport frame generator divides a transport frame containing multiple client signals into several transmission signals. Subcarrier transmission units convert these signals into optical signals using different optical carriers for transmission. The subcarrier reception units then receive and convert the optical signals back into reception signals. A transport frame termination unit combines these reception signals to restore the original transport frame, while a time-demultiplexing processor separates the client signals. A time slot control unit allocates new time slots when time-multiplexing the client signals and manages power supply to the transmission and reception units.
