Abstract: A network system, a network control method, and a control apparatus are provided that can easily achieve assurance of the quality of a network service and optimization of the throughput of an entire system. A network control apparatus (11) controls a network having a multi-layer structure, sets a first layer path that provides virtual network functions for a network service on a first layer, monitors whether or not the network service on the first layer fulfills a required service level, and depending on a result of the monitoring, changes a setting of a packet header so that the first layer path will be switched at an end point of the network service. This causes a resource on a second layer, which is a lower layer than the first layer, to change.

Abstract: Communication allowance determination means determines, using information of a packet received by a packet relay unit and based on a policy which is information associating a match condition with communicability information, whether to allow or not to allow communication to a destination unit for the packet that meets the match condition, the match condition being information identifying the packet, and the communicability information indicating whether to allow or not to allow the communication to the destination unit for the packet that meets the match condition. Rule setting means sets, at least in the packet relay unit receiving the packet, a rule of executing a process for suppressing forwarding of the packet to the destination unit, on condition that the communication allowance determination means determines not to allow the communication to the destination unit for the packet that meets the match condition.
