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 (10) controls a network (20) having a multi-layer structure, monitors whether or not a network service on a first layer fulfills a required service level, and depending on a result of the monitoring, changes a setting of a packet header so that resources on the first layer will be changed, wherein resources on the lower layer are changed in accordance with a change in the setting of the packet header.
Claims12
A network control apparatus for controlling a network having a multi-layer structure, comprising:
- a network monitor that monitors whether or not a network service on a first layer fulfills a required service level, a network service path being preset on the first layer, the network service path providing the same virtual network functions as at least part of those of the network service;
- and
- a controller configured to:
- change, depending on a result of the monitoring, a setting of a packet header so that resources on the first layer will be changed;
- and
- change the setting of the packet header so that a path on the first layer will be switched to the network service path, depending on the result of the monitoring,
- wherein the resources on a second layer, which is a lower layer than the first layer, are changed in accordance with a change in the setting of the packet header.
A network control method for controlling a network having a multi-layer structure by a network control apparatus, comprising:
- monitoring whether or not a network service on a first layer fulfills a required service level, a network service path being preset on the first layer, the network service path providing the same virtual network functions as at least part of those of the network service;
- and
- changing, depending on a result of the monitoring, a setting of a packet header so that resources on the first layer will be changed;
- and
- changing the setting of the packet header so that a path on the first layer will be switched to the network service path, depending on the result of the monitoring,
- wherein the resources on a second layer, which is a lower layer than the first layer, are changed in accordance with a change in the setting of the packet header.
A network system comprising:
- a network having a multi-layer structure;
- and
- a control apparatus for controlling the network,
- wherein the control apparatus is configured to:
- monitor whether or not a network service on a first layer fulfills a required service level, a network service path being preset on the first layer, the network service path providing the same virtual network functions as at least part of those of the network service;
- depending on a result of the monitoring, change a setting of a packet header so that resources on the first layer will be changed;
- and
- change the setting of the packet header so that a path on the first layer will be switched to the network service path, depending on the result of the monitoring,
- wherein the resources on a second layer, which is a lower layer than the first layer, are changed in accordance with a change in the setting of the packet header.
