Title: Masanori Kamata: Innovator in Broadband Technology

Introduction

Masanori Kamata is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of broadband technology, holding a total of 7 patents. His work focuses on enhancing multicast accounting systems and packet forwarding methods, which are crucial for efficient data transmission in modern networks.

Latest Patents

One of Kamata's latest patents is the "Multicast Accounting Control System and Broadband Access Server." This invention differentiates listening or viewing charges based on bit rates depending on distributed programs. It features a broadband access server that manages user channels and replicates multicast packets. The system includes a counter that tracks the number of distributed multicast packets and bytes for each multicast group address. When a user joins or leaves a multicast group, the system sends the counter values and a multicast session ID to a multicast accounting radius server, which provides accounting based on these metrics.

Another notable patent is the "Packet Forwarding Control Method and Packet Forwarding Apparatus." In this invention, an edge side gateway (EGW) acquires layer 2 tunneling control information from an authentication server upon receiving a PADI from a user terminal. The EGW stores the correspondence between the source address and the tunneling control information, encapsulates the PADI, and transmits it to the wide area Ethernet network. A core side gateway (CGW) then decapsulates the received packet and forwards it to a broadband access server, ensuring efficient packet forwarding for users.
