The present invention contributes to improvement of connectivity of a virtual network established in each of a plurality of sites. In a communication system, a virtual network management apparatus includes: an endpoint management unit configured to manage virtual network endpoints of control target communication nodes; a policy control unit configured to select, when a communication occurs between two sites in each of which a virtual network is configured, virtual network endpoints for realizing the communication from among the virtual network endpoints managed by the endpoint management unit; and a network configuration unit configured to generate and manage a third virtual network that connects the selected endpoints to each other. A control apparatus configured to notify the virtual network management apparatus of occurrence of a communication between the two sites and control a communication node group including the communication nodes having the virtual network endpoints so as to configure the third virtual network on the basis of an instruction from the virtual network management apparatus. |
