Abstract
An object is to provide a logical network construction system. A logical network construction system is provided with first and second gateway devices and a controller which communicate with each other via a network, a source device, a destination device, and a storage unit in which an entire device connection list and an entire route definition list are stored. A controller constructs a logical network for communication between a source device connected to a first port of a first gateway device and a destination device connected to a second port of a second gateway device on the basis of an entire device connection list and an entire route definition list.
Claims10
A logical network construction system comprising:
- a first gateway device, a second gateway device, and a controller connected to a network and communicating with each other via the network;
- a transmission source device connected to a first port of the first gateway device and communicating with the first gateway device;
- a destination device connected to a second port of the second gateway device and communicating with the second gateway device;
- a storage unit in which an entire device connection list and an entire route definition list are stored;
- wherein
- in the entire device connection list, connection information for specifying the first gateway device to which the transmission source device is connected and the second gateway device to which the destination device is connected is registered,
- in the entire route definition list, information for specifying the destination device with which the transmission source device should communicate is registered, and
- the controller constructs a logical network for communication between the source device connected to the first port of the first gateway device and the destination device connected to the second port of the second gateway device based on the entire device connection list and the entire route definition list.
A gateway device comprising:
- a storage unit that stores a first route definition list in which the device identifier of the source device, the device identifier of the destination device, and the network address of the transfer destination gateway device are registered in association with each other, and a first device connection list in which the port identifier of the first port and the device identifier of the source device are registered in association with each other;
- wherein
- the transfer destination gateway device is specified by referring to the first route definition list and the first device connection list, and the communication between the transmission source device and the transfer source gateway device is transferred to the specified transfer destination gateway device.
A controller comprising:
- a storage unit that stores an entire device connection list and an entire route definition list in which information for specifying the destination device with which the source device is to communicate is registered in which connection information for specifying a first gateway device to which a source device is connected and a second gateway device to which a destination device is connected is registered;
- wherein
- on the basis of the entire device connection list and the entire route definition list, an instruction for constructing a logical network for communication between the source device connected to the first port of the first gateway and the destination device connected to the second port of the second gateway is transmitted to the first gateway device and the second gateway device.
