Route control and resource reservation mechanisms are integrated so as to perform multicast communication efficiently. In response to a connection establishment request from a new receiver (host F) with a sender (host A), resources are temporarily reserved and a route suitable for the receiver initiated request is selected, and the connection establishment request is transferred to an upper node. A similar process is performed in host D, and a connection establishment request is transferred to an upper node. In host C, resources are reserved, a confirmation request is transferred to a lower node, and the confirmation request is transferred to the host F via host D. In host F, the quantity of resources is adjusted, and the establishment of the connection with host A is completed.
