Provided is a network capable of achieving both fine path control based on a packet feature and easiness in setting and operation. The network includes a data forwarding node including: a logical network topology management unit managing a correspondence relationship among at least two different logical network topologies generated by applying different policies to a physical network topology and data traffic conditions to which the logical network topologies are applied; and a packet processing unit selecting a logical network topology corresponding to data traffic to which an incoming packet belongs, determining a packet forwarding destination, and transmitting the incoming packet. The data forwarding node selects a logical network and forwards a packet, based on data traffic. |
