Latest Patents

Ishihara's latest patents include a multicast data communication method and system, as well as a repeater and medium for storing repeating programs. His innovative multicast data communication system is designed to provide high security and prevent issues such as attacks from malicious users who create numerous meaningless tables at nodes within the network. The system allows clients to regularly transmit request packets to a server. A node receives these request packets and subsequently receives either a delivery-table-creation packet or a delivery packet from the server. If the node does not have a delivery table corresponding to the server, it creates one, registering the addresses of clients and their request packet arrival times. The node then regularly transmits the request packet to the server. Upon receiving a delivery packet from the server, the node duplicates and delivers it only to those clients whose request packet arrival times, registered in the delivery table, fall within a specified period from the arrival of the delivery packet.
