Abstract
High-speed control of disaggregated network systems is implemented. A control device includes a main memory and an interface. The main memory shares management information contained in memory spaces possessed by a plurality of respective component devices connected and stores the management information as integrated management information. When the management information is to be updated, the interface transmits an update signal for updating the management information to the component devices and receives a response signal to the update signal from the component devices.
Claims6
A control method comprising:
- setting identifiers for respective memory spaces possessed by a plurality of respective component devices connected in order to share and manage management information contained in the memory spaces;
- storing the management information by associating the memory spaces with the identifiers;
- and
- transmitting an update signal for updating the management information to the component devices when the management information is to be updated,
- wherein:
- a control device transmits the update signal to one memory space of a first one of the plurality of the component devices,
- the first one of the plurality of component devices performs update processing of the memory space and transmits the update signal to a memory space of a next component device, which is a next connection destination, and the connected component devices sequentially repeat update processing of the memory spaces in connection order, and
- the control device receives a response signal from a last component device.
A control device comprising:
- a main memory configured to share management information contained in memory spaces possessed by a plurality of respective component devices connected and store the shared management information as integrated management information;
- and
- an interface configured to transmit an update signal for updating the management information to the component devices and receive a response signal, responsive to the update signal, from the component devices, when the management information is to be updated,
- wherein:
- the control device transmits the update signal to one memory space of a first one of the plurality of component devices,
- the first one of the plurality of component devices performs update processing of the memory space and transmits the update signal to a memory space of a next component device, which is a next connection destination, and connected component devices sequentially repeat update processing of the memory spaces in connection order, and
- the control device receives a response signal from a last component device.
A control method comprising:
- setting identifiers for respective memory spaces possessed by a plurality of respective component devices connected in order to share and manage management information contained in the memory spaces;
- storing the management information by associating the memory spaces with the identifiers;
- and
- transmitting an update signal for updating the management information to the component devices when the management information is to be updated,
- wherein:
- a control unit generates the update signal,
- a signal transmission/reception unit transmits the update signal to the component devices via a transceiver,
- the control unit determines whether a response signal is received within a predetermined time,
- when the response signal is received within the predetermined time, the control unit determines whether the response signal includes an error message, and
- when the response signal does not include the error message, the control unit updates integrated management information.
