Abstract
The present invention reduces the labor required for setting VLAN information in the ports of the communication nodes in a centralized-control-type communication system. A control apparatus includes: a connection detection unit configured to detect connection of a terminal or a virtual machine to a control target communication node; a first VLAN information determination unit configured to determine VLAN information that is set in a port of the communication node, the port having been connected to the terminal or the virtual machine, on the basis of a virtual network to which the detected terminal or virtual machine belongs; and a VLAN information setting unit configured to set the determined VLAN information in the port.
