PROBLEM TO BE SOLVED: To efficiently transfer broadcast and multicast when a virtual network is configured in a network over a plurality of domains.SOLUTION: A data transfer system comprises: a first data transfer server provided with respect to a tunnel termination point which belongs to a first domain; and a second data transfer server provided with respect to a tunnel termination point which belongs to a second domain. The first data transfer server, when receiving a packet from the tunnel termination point which belongs to the first domain, transfers a packet to the second data transfer server and tunnel termination points other than a transfer source of the packet of the tunnel termination point which belongs to the first domain. The second data transfer server, when receiving a packet from the first data transfer server, transfers a packet to the tunnel termination point which belongs to the second domain. |
