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 () 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.
