Communication system, virtual network management apparatus, virtual network management method and program
View Patent ↗A communication system includes: a network configuration memory that stores network configuration information of a first layer in which an area of the first layer whose low level configuration is desired to be concealed is represented by a preset symbol and that also stores network configuration information of a second layer showing the area represented by the preset symbol. The system also includes a network configuration management section that allows a first user to manage a network of the first layer using the network configuration information of the first layer and that also allows a second user to manage a network of the second layer using at least the network configuration information of the second layer.
1. A communication system, comprising:
a network configuration memory that stores:
network configuration information of a first layer in which an area of the first layer whose low level configuration is desired to be concealed is represented by a preset symbol; and
network configuration information of a second layer showing the area represented by the preset symbol;
a network configuration management section that allows:
a first user to manage a network of the first layer using the network configuration information of the first layer; and
a second user to manage a network of the second layer using at least the network configuration information of the second layer;
a mapping information memory that stores a relation of correspondence between a first identifier for identifying a user in the first layer, and a second identifier for identifying a user in the second layer; and
a switch controller that causes a switch on a path of a user packet to write the second identifier in a header of the user packet, based on the first identifier contained in the user packet.
2. The communication system according to claim 1 , wherein, the second identifier is stored in a preset area of an additional header that stores an identifier of the first layer.
3. The communication system according to claim 2 , wherein,
the network of the second layer showing the area represented by the preset symbol is associated with the network of the first layer in a one to multiple relation.
4. The communication system according to claim 1 , wherein, the second identifier is stored in a preset area of the header of the user packet.
5. The communication system according to claim 4 , wherein,
the network of the second layer showing the area represented by the preset symbol is associated with the network of the first layer in a one to multiple relation.
6. The communication system according to claim 1 , wherein,
the network of the second layer showing the area represented by the preset symbol is associated with the network of the first layer in a one to multiple relation.
7. A virtual network management apparatus comprising:
a network configuration memory that stores:
network configuration information of a first layer in which an area of the first layer whose low level configuration is desired to be concealed is represented by a preset symbol; and
network configuration information of a second layer showing the area represented by the preset symbol;
a network configuration management section that allows:
a first user to manage a network of the first layer using the network configuration information of the first layer; and
a second user to manage a network of the second layer using at least the network configuration information of the second layer;
a mapping information memory that stores a relation of correspondence between a first identifier for identifying a user in the first layer, and a second identifier for identifying a user in the second layer; and
a switch controller that causes a switch on a path of a user packet to write the second identifier in a header of the user packet, based on the first identifier contained in the user packet.
8. A method for management of a virtual network including a network configuration memory that stores network configuration information of a first layer in which an area of the first layer whose low level configuration is desired to be concealed is represented by a preset symbol, and that also stores network configuration information of a second layer showing the area represented by the preset symbol, the method comprising:
accepting an operation on a network of the first layer made by a first user with the use of the network configuration information of the first layer;
accepting an operation on a network of the second layer made by a second user with the use of at least the network configuration information of the second layer;
storing a relation of correspondence between a first identifier for identifying a user in the first layer, and a second identifier for identifying a user in the second layer; and
causing a switch on a path of a user packet to write the second identifier in a header of the user packet, based on the first identifier contained in the user packet.
9. The method according to claim 8 , wherein:
the second identifier is stored in a preset area of an additional header that stores an identifier of the first layer.
10. The method according to claim 8 , wherein:
the second identifier is stored in a preset area of the header of the user packet.
11. The method according to claim 8 , wherein:
the network of the second layer showing the area represented by the preset symbol is associated with the network of the first layer in a one to multiple relation.
12. A non-transitory computer-readable recording medium storing a program that causes a computer, arranged in a virtual network including a network configuration memory that stores network configuration information of a first layer in which an area of the first layer whose low level configuration is desired to be concealed is represented by a preset symbol, and that also stores network configuration information of a second layer showing the area represented by the preset symbol, to execute a method, the method comprising:
accepting an operation on a network of the first layer made by a first user with the use of the network configuration information of the first layer;
accepting an operation on a network of the second layer made by a second user with the use of at least the network configuration information of the second layer;
storing a relation of correspondence between a first identifier for identifying a user in the first layer, and a second identifier for identifying a user in the second layer; and
causing a switch on a path of a user packet to write the second identifier in a header of the user packet, based on the first identifier contained in the user packet.
13. The non-transitory computer readable recording medium according to claim 12 , wherein:
the second identifier is stored in a preset area of an additional header that stores an identifier of the first layer.
14. The non-transitory computer readable recording medium according to claim 12 , wherein:
the second identifier is stored in a preset area of the header of the user packet.
15. The non-transitory computer readable recording medium according to claim 12 , wherein:
the network of the second layer showing the area represented by the preset symbol is associated with the network of the first layer in a one to multiple relation.
