ABSTRACT:
A multicast data communication system is provided that has high security, and prevents problems such as an attack by a malicious user creating a great number of meaningless tables at nodes in the network. Clients regularly transmit request packets toward a server; a node receives the request packet, and subsequently receives a delivery-table-creation packet or a delivery packet from the server; if the node has no delivery table corresponding to the server, the node creates the delivery table, registers the addresses of the clients, and their request packet arrival times, and regularly transmits the request packet toward the server; when the node has received a delivery packet from the server, the node duplicates and delivers the delivery packet only to those clients whose request packet arrival times, registered in the delivery table, are within a fixed period from the arrival of the delivery packet.
