1. A load balancing system, comprising:
an application information storage configured to store information obtained by associating application information including flow characteristics of an application of a flow constituted by a packet with a flow identifier for identifying the flow of the packet;
an acquisition unit, implemented using one or more computing devices, configured to acquire, based on an input port receiving a packet, application information of a flow constituted by the packet from the application information storage; and
an output unit, implemented using one or more computing devices, configured to output the packet received by the input port to a packet transfer apparatus in a load state indicating that a load due to the flow of the flow characteristics is determined to be less than a predetermined threshold among a plurality of packet transfer apparatuses according to the flow characteristics included in the application information acquired by the acquisition unit.
