Description

  The present invention relates to an automatic setting system, and more particularly, to an automatic setting system for device identification information and an IP address in a linear or ring network.

  In a backbone network device that forms a network in a conventional linear form (straight) or ring form (annular), control that directly connects device identification information and IP address to each backbone network device It was necessary to use the device and set it individually.

  A conventional apparatus identification information and IP address setting method in a backbone network apparatus forming a linear network will be described with reference to FIG.

  Referring to FIG. 1, a conventional linear network includes a backbone network device 1 and a control terminal 2.

  The backbone network device 1 (1-i, i = 1 to X: X is the number of devices) forms a linear network.

  The control terminals 2 (2-i, i = 1 to X) are connected one-to-one to the backbone network device 1 that forms a pair. For example, the control terminal 2-1 is connected to the backbone network device 1-1, and the control terminal 2-2 is connected to the backbone network device 1-2.

  The conventional apparatus identification information and IP address setting method in a backbone network apparatus that forms a linear network has the following problems.

  For example, when setting device identification information and an IP address for each backbone network device, it is necessary to set before each backbone network device, and it is necessary to connect and set a control terminal individually. This means that the device identification information and the IP address cannot be set remotely.

As a related technique, Japanese Patent Laid-Open No. 2003-046519 (Patent Document 1) discloses an address automatic setting method.
In this prior art, the setting machine detects a free IP address and transmits a network address including the free IP address by broadcast. Broadcast transmits information to all devices on the network. Next, the device to be set decodes the network information in the broadcast packet and sets a network address such as an IP address. After setting the network address, a confirmation packet is transmitted from the set device to the set device by unicast. Unicast sends information only to one designated partner. In unicast, communication is not possible unless the correct network setting is performed. Therefore, the setting machine receives a confirmation packet from the setting machine, thereby confirming that the correct network setting has been performed.

Japanese Patent Laying-Open No. 2005-327075 (Patent Document 2) discloses a network configuration setting method, a network-compatible host device, and a network-compatible target device.
In this prior art, when the host device finishes assigning the target IP address and transmits a network setting packet, it waits for a network setting response packet. When the target device receives the network setting packet and determines that it is a request packet based on the packet type field, the target device extracts the target IP address, subnet mask, gateway address, and DNS server address from the received network setting packet. Change the network settings of the device. The target device reboots to make the network configuration change effective and updates the network configuration page URI based on the new IP address after reboot. The updated network setting page URI is set in the target device network setting page URI field, the identification information indicating the response packet is set in the packet type field, and the identification information indicating that the network setting request is accepted in the message type field To broadcast the network setting packet to the network. Next, when the host device receives the network setting packet and determines that it is a response packet based on the packet type field, the host device sets the network setting page URI of the target device from the target device network setting page URI field of the received network setting packet. , The Web browser is activated and the network setting page specified by the network setting page URI is displayed.

Japanese Patent Laid-Open No. 08-237285 (Patent Document 3) discloses an automatic setting method of an Internet protocol address.
In this prior art, in order to determine the IP address of each terminal and notify each terminal, the host individually sends a notification packet generated according to the UDP format, for example, to each terminal. Each terminal receives the notification packet sent by the host, sets the IP address notified by the received notification packet in the IP address storage table owned by each terminal, and registers the physical address of the host. Communication is performed using the set IP address.

Japanese Laid-Open Patent Publication No. 11-33270 (Patent Document 4) discloses a network system.
In this conventional technology, among the setting information necessary for each network device at the management terminal that manages the network devices on the network system, only the setting information that only each device has as a friend is given to each other. By mutually referencing the necessary setting information, all the setting information required by each network device is automatically processed, and the setting information is created and distributed, so that each network device is included in the entire network configuration. Automatically process and distribute all setting information required by.

Next, with reference to FIGS. 3A to 3D, device identification information and IP address automatic setting operations in a linear network formed by the backbone network device of FIG. 2 will be described.
(1) Step S101
First, the operator uses the control terminal 20 directly connected to the parent backbone network device 10-1, and the network type (linear form) and the number of devices (for the parent backbone network device 10-1) For example, X units), a network name (for example, “linear network # 1”) that is the basis of device identification information, and a list of available IP addresses (for example, “192.168.1.1 to 192.168 .. 1. X ") is set.
(2) Step S102
Network form (linear form), number of apparatuses (for example, X units), network name (for example, “linear network # 1”) that is the basis of apparatus identification information, and list of available IP addresses (for example, “192. 168.1.1 to 192.168.1.X ") is set as the parent backbone network device 10-1, the device identification information of the device is changed to" linear network # 1-1 " Is set to “192.168.1.1” and the number of devices that have been set is changed to 1.
(3) Step S103
Next, the main trunk network device 10-1 confirms the set network configuration. Here, it is confirmed whether the network form is a linear form. As a result of the confirmation, when the network form is not the linear form, the process is terminated.
(4) Step S104
As a result of the confirmation, when the network form is a linear form, the backbone network apparatus 10-1 serving as a parent has only one DCC (Data Communication Channel) used by the own apparatus, and therefore, via this DCC (FIG. 2). In the example, on the DCC1 side), the setting request packet is used for the backbone network device 10-2 which is the adjacent device, the device identification information is “linear network # 1-2”, and the IP address is “192. Send a request to set to "168.1.2".
(5) Step S105
The backbone network device 10-2 that has received the setting request packet checks whether the device identification information and the IP address of the own device are set. When the device identification information of the own device and the IP address are set, the setting completion packet is sent back to the parent backbone network device 10-1 via the received DCC.
(6) Step S106
When the device identification information and the IP address of the own device are not set, the backbone network device 10-2 sets the device identification information of the own device to “linear network # 1-2” and the IP address of the own device. Set to “192.168.1.2”. When the setting is completed, the backbone network device 10-2 sends back the setting completion packet to the parent backbone network device 10-1 via the received DCC.
(7) Step S107
After receiving the setting completion packet from the backbone network device 10-2, the parent backbone network device 10-1 adds 1 to the number of devices that have been set, and then completes the set number of devices and the setting. Compare the number of devices. 1 plus means incrementing the value of a variable indicating the number of devices that have been set by 1 (increment).
(8) Step S108
As a result of the comparison, if there is a device that has not been set yet, the parent backbone network device 10-1 passes through the backbone network device 10-2 to the next backbone network device 10-3. Setting information is sent using a setting request packet.
(9) Step S109
The backbone network device 10-2 that has received the setting request packet for the backbone network device 10-3 from the backbone backbone network device 10-1 is set with the device identification information and the IP address of its own device. Make sure that If the device identification information and the IP address are not set, the device identification information and the IP address are set in the own device (return to step S106).
(10) Step S110
When the device identification information and the IP address are set, the backbone network device 10-2 sends a setting request packet to a DCC port different from the DCC port that received the setting request packet. That is, a setting request packet is sent to the backbone network device 10-3 via another DCC.
(11) Step S111
The backbone network device 10-3 that has received the setting request packet confirms whether the device identification information of the own device and the IP address are set.
(12) Step S112
When the device identification information and the IP address of the own device are not set, the backbone network device 10-3 sets the device identification information and the IP address of the own device.
When the setting is completed, the backbone network device 10-3 sends back a setting completion packet to the parent backbone network device 10-1 via the DCC that has received the setting request packet. The backbone network device 10-2 that has received the setting completion packet from the backbone network device 10-3 sends a setting request packet to a DCC port different from the DCC port that has received the setting request packet.
(13) Step S113
After receiving the setting completion packet from the backbone network device 10-3, the parent backbone network device 10-1 adds 1 to the number of devices that have been set, and then completes the set number of devices and the setting. Compare the number of devices.
(14) Step S114
If there is a device that has not been set as a result of the comparison, the parent backbone network device 10-1 sends setting information to the next backbone network device via the DCC 1 side using a setting request packet. . Thereafter, similarly, exchange of a setting request packet and a setting completion packet is performed, and the backbone network device 10-1 as a parent sets device identification information and an IP address in order to each backbone network device. That is, the same operation as the setting for the backbone network device 10-2 and the backbone network device 10-3 described above is repeated up to the backbone network device 10-X.
(15) Step S115
After receiving the setting completion packet from the backbone network device 10-X, the backbone network device 10-1 serving as the parent adds 1 to the number of devices that have been set, and then completes the set number of devices and the setting. Compare the number of devices. As a result of the comparison, since the number of devices set matches the number of devices that have been set, it is determined that the settings of all the backbone network devices have been completed.
(16) Step S116
Finally, the parent backbone network device 10-1 notifies the control terminal 20 of device identification information and IP address combination list information.
(17) Step S117
Upon receiving the device identification information and the IP address combination list information from the parent backbone network device 10-1, the control terminal 20 automatically creates / updates the device identification information and the IP address combination list. To do.

The network name setting unit 13 sets and manages information indicating a network name (for example, “linear network # 1”) that is the basis of the device identification information. The device identification information setting unit 14 sets and manages device identification information (for example, “linear network # 1-1”) of the own device. The IP address setting unit 15 sets and manages the IP address (for example, “192.168.1.1”) of the own apparatus. The usable IP address list setting unit 16 can use an IP address list (for example, “192.168.1.1” that can be used by the backbone network device 10 (for example, “10-1 to 10-X”) belonging to the same network. To 192.168.1.X "). The DCC communication unit 17 communicates with an adjacent backbone network device via a DCC (Data Communication Channel) used by the own device. Here, the setting request packet is transmitted to the adjacent backbone network device, and the setting completion packet is received from the adjacent backbone network device. Packets to be transmitted / received include packets for other backbone network devices other than the adjacent backbone network device. In addition, in the case where the backbone network device 10 is the parent backbone network device 10-1, communication is also performed with the control terminal 20.

Conversely, in step S103 of the first embodiment shown in FIG. 3A, when the network form is a ring form, the processes after step S204 of this embodiment may be performed.
(4) Step S204
As a result of confirmation, when the network form is a ring form, the backbone network apparatus which is an adjacent apparatus via the smaller DCC number used by the own apparatus (the smaller number in the example of FIG. 6) A request is sent to 10-2 to set the device identification information to “ring network # 1-2” and the IP address to “192.168.1.2” using the setting request packet. However, in reality, contrary to the above, via the non-young DCC number (the one with the larger number) (in the example of FIG. 6, on the DCC2 side) to the backbone network device 10-X that is an adjacent device. It is also possible to transmit a setting request packet. Alternatively, a setting request packet corresponding to each of the DCC1 side and the DCC2 side may be transmitted. In this case, the setting can be advanced simultaneously on the backbone network device 10-2 side and the backbone network device 10-X side.
(5) Step S205
The backbone network device 10-2 that has received the setting request packet checks whether the device identification information and the IP address of the own device are set.
(6) Step S206
When the device identification information and the IP address of the own device are not set, the backbone network device 10-2 sets the device identification information of the own device to “ring network # 1-2” and the IP address of the own device. Set to “192.168.1.2”. When the setting is completed, the backbone network device 10-2 returns a setting completion packet to the parent backbone network device 10-1 via the DCC that has received the setting request packet.
(7) Step S207
After receiving the setting completion packet from the backbone network device 10-2, the parent backbone network device 10-1 adds 1 to the number of devices that have been set, and then completes the set number of devices and the setting. Compare the number of devices.
(8) Step S208
If there is a device that has not been set as a result of the comparison, the parent backbone network device 10-1 uses the setup request packet to send the setup information to the next backbone network device 10-3 via the DCC1 side. send.
(9) Step S209
The backbone network device 10-2 that has received the setting request packet for the backbone network device 10-3 from the backbone backbone network device 10-1 is set with the device identification information and the IP address of its own device. Make sure that If the device identification information and the IP address are not set, the device identification information and the IP address are set in the own device (return to step S206).
(10) Step S210
When the device identification information and the IP address are set, the backbone network device 10-2 sends a setting request packet to a DCC port different from the DCC port that received the setting request packet.
(11) Step S211
The backbone network device 10-3 that has received the setting request packet confirms whether the device identification information of the own device and the IP address are set.
(12) Step S212
When the device identification information and the IP address of the own device are not set, the backbone network device 10-3 sets the device identification information and the IP address of the own device. When the setting is completed, the backbone network device 10-3 sends back a setting completion packet to the parent backbone network device 10-1 via the DCC that has received the setting request packet. The backbone network device 10-2 that has received the setting completion packet from the backbone network device 10-3 sends a setting request packet to a DCC port different from the DCC port that has received the setting request packet.
(13) Step S213
After receiving the setting completion packet from the backbone network device 10-3, the parent backbone network device 10-1 adds 1 to the number of devices that have been set, and then completes the set number of devices and the setting. Compare the number of devices.
(14) Step S214
If there is a device that has not yet been set as a result of the comparison, the parent backbone network device 10-1 sends setting information to the next backbone network device using the setting request packet via the DCC1 side. Thereafter, similarly, exchange of a setting request packet and a setting completion packet is performed, and the backbone network device 10-1 as a parent sets device identification information and an IP address in order to each backbone network device. That is, the same operation as the setting for the backbone network device 10-2 and the backbone network device 10-3 described above is repeated up to the backbone network device 10-X.
(15) Step S215
After receiving the setting completion packet from the backbone network device 10-X, the backbone network device 10-1 serving as the parent adds 1 to the number of devices that have been set, and then completes the set number of devices and the setting. Compare the number of devices. As a result of the comparison, since the number of devices set matches the number of devices that have been set, it is determined that the settings of all the backbone network devices have been completed.
(16) Step S216
Finally, the parent backbone network device 10-1 notifies the control terminal 20 of device identification information and IP address combination list information.
(17) Step S217
Upon receiving the device identification information and the IP address combination list information from the parent backbone network device 10-1, the control terminal 20 automatically creates / updates the device identification information and the IP address combination list. To do.

  As described above, according to the present invention, device identification information and an IP address can be automatically set in each backbone network device in a backbone network device that forms a network in a linear form or a ring form. It is characterized by that.

  The control terminal 20 is directly connected to the parent backbone network device 10-1. The operator uses the control terminal 20 to set a network form, the number of devices, a network name that is the basis of device identification information, and a list of available IP addresses for the parent backbone network device 10-1. . The parent backbone network device 10-1 in which the network name that is the basis of the device identification information and the list of available IP addresses is set, uses the setting request packet, and is sent from the backbone network device 10-2. The device identification information and the IP address are notified to the backbone network device 10-X in order. The backbone network device 10-X receives the device identification information and the IP address from the backbone network device 10-2 that has received the device identification information and the IP address from the parent backbone network device 10-1. After that, the setting completion packet is notified to the parent backbone network device 10-1 that the setting has been completed. After the master network device 10-1 as a parent receives the notification of the completion of setting from all the core network devices that form the network in the linear form, the combination of the device identification information and the IP address to the control terminal 20 Notify list information. Upon receiving the device identification information and the IP address combination list information from the parent backbone network device 10-1, the control terminal 20 automatically creates the device identification information and IP address combination list.

  In this way, in the present invention, the parent backbone network device 10-1 sends a setting request packet from the backbone network device 10-2 forming the linear network to the backbone network device 10-X. The device identification information and the IP address to be used are notified, and the device identification information and the IP address are received from the main network device 10-2 that has received the device identification information and the IP address. X sets the device identification information and IP address in its own device, and notifies the parent backbone network device 10-1 that the setting has been completed, so the device identification information and the IP address are Can be automatically set for each backbone network device.
