Description

Description: TECHNICAL FIELD The present invention relates to a network having a plurality of terminal devices and a network management device that controls a connection between them.

(Prior Art) For example, in a financial institution or the like, a host computer installed in a management center controls a large number of terminal devices installed in each branch. In addition, each branch is provided with a terminal controller that controls communication with the host computer and distributes instructions and the like from the host computer to each terminal device installed in the branch. Further, the terminal controller is provided with a network management device for controlling communication between the terminal devices installed in the branch. This network management device controls one sub-network including several terminal devices connected to it, and enables mutual communication without the intervention of a host computer.

These terminal devices include not only those for which a specialized operator inputs and outputs various data using a keyboard or the like, but also devices for monitoring or managing the flow and status of various business operations. Further, an automatic cash transaction machine (ATM) directly handled by the customer also functions as one terminal device.

The operation of the conventional network will be described with reference to FIGS. 2 and 3.

FIG. 2 is a diagram for explaining the operation of the conventional network.

Here, the host computer 1 is connected to the network management device 2. Here, for example, this network management device is connected to the terminal devices 11 to 14 and ATM2.
Consider the case of controlling 0 mutual communication.

Therefore, for example, a case where the ATM 20 outputs a predetermined message to the terminal device 13 will be described.

FIG. 3 shows a connection request, that is, an interlocking telegram issued from the ATM 20 in such a case. Therefore, it is assumed that the operating state of the ATM 20 is monitored by the terminal device 13 shown in FIG. In such a case, it is read that the ATM 20 performs predetermined communication with the terminal device 13 as interlocking.

That is, in FIG. 3, the ATM transmits the connection request 30 with the contents that the destination 31 is the terminal device 13, the communication source 32 is ATM, and the message 33 is "ATM voucher is empty".

In FIG. 2, the network management device 2 receives this message, selects the terminal device 13, and controls to display the content of the message 33 on the display thereof.

The conventional network operates as described above.

(Problems to be solved by the invention) By the way, in financial institutions, there are various management operations such as management of cash accounting, management of issuing passbooks, etc. These operations are carried out by monitoring the terminal devices installed in the etc. Therefore, each terminal device is associated with the office in advance according to the business, and the network management device controls the connection by regarding the terminal device as an administrator.

Therefore, the terminal device connected to the predetermined connection request of the ATM 20 as shown in FIG. 3 is fixed, and the message is always displayed on the terminal device on the desk of the officer in charge of its management. It will be.

However, for example, when the officer in charge is absent, some other officer must manage the ATM. For this, for example, there is a method of moving the terminal device near the desk of the proxy seat, but the terminal device itself is large, or there is a distance between the absent office seat and the proxy seat. It is not realistic when there is.

It is also possible to change the attribute of the terminal device on the desk of the corresponding absent official seat so that the electronic message addressed to the absent official seat is transferred to the terminal device of the acting official seat. However, usually, in the network management device, the attribute of the terminal device is set by hardware, and the change is complicated and cannot be flexibly coped with.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a network in which an operator or the like can easily change the attributes of a terminal device by using the terminal device and realize the substitution of officers' seats. It is intended.

(Means for Solving the Problems) In the network of the present invention, a plurality of terminal devices are connected,
There is a network management device for controlling the connection between these terminal devices, and this network device has a physical name for identifying each terminal device and a logical name indicating the role of each terminal device in the network. Storage means for storing a correspondence table for associating with each other, correspondence table processing means for requesting correspondence table processing from any one of the terminal devices and rewriting the correspondence table, and the logical device from the terminal device or another external device. Name conversion means for converting to a physical name when there is a connection request using a name, and connection control means for requesting execution of connection with the terminal device for which a connection request has been made using this physical name. It is characterized by being provided.

(Operation) In the above network, each terminal device makes a connection request to the network management device using a logical name. The logical name is given according to the role of the terminal device, and is a name that directly indicates a responsible officer or the like who uses the terminal device. Then, in the network management device, a correspondence table in which the logical name is associated with the physical name for identifying each terminal is stored.

Therefore, the physical name can be extracted by using the logical name and the connection control can be performed, and by rewriting this correspondence table by a predetermined process, an arbitrary terminal device can be easily set as the one for a predetermined responsible officer's seat. It becomes possible.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the network of the present invention.

In the figure, this network is composed of a network management device 2 connected to a host computer 1 and terminal devices 11, 12, 13 to 20 connected to this network management device 2. Further, the network management device 2 is configured to include a host communication control virtual terminal 3 and a network management virtual terminal 4.

The network management device 2 itself is composed of various known communication control microprocessors and the like. In this embodiment, the functions necessary for explaining the present invention, that is, the host communication control function and the network management, are included in this embodiment. I took out only the parts with connections and displayed them as virtual terminals. In addition, the network management virtual terminal 4
A connection control means 5, a name conversion means 6, a correspondence table processing means 7, and a correspondence table storage means 8 are provided.

Here, the host communication control virtual terminal 3 controls communication with the host computer 1, and the host computer 1 itself communicates with the host communication control virtual terminal 3 to perform various operations for each terminal device 11 to 20. It is possible to send and receive data. This technique is a technique well known by a known general communication control technique, and a description thereof will be omitted.

The network management virtual terminal 4 is a device for managing the mutual connection of the terminal devices 11 to 20 connected to the network management device 2.

The connection control means 5 analyzes a connection request received from any of the terminal devices and realizes connection with the terminal device according to the request.

By the way, in the network management device 2 of the present invention, the network management virtual terminal 4 includes a name conversion means 6, a correspondence table processing means 7, and a correspondence table storage means 8.

The contents of the correspondence table of the correspondence table storage means 8 are specifically shown in FIG. This table is a table in which a logical name 41 and a physical name 42 are associated with each other, which is registered in advance in a secondary storage device (not shown) and stored by the secondary storage device when the network management device 2 is started up. It is stored in the means 8.

The logical name 41 is, for example, AA staff, BB staff, CC staff, DD staff, EE staff ... This is a name set with focus on the role. Further, the physical name 42 is a name for physically specifying each terminal device such as the terminal devices 11, 12, 13 ,.

For example, when there is a connection request using the logical name of AA officer, the name conversion unit 6 refers to this correspondence table to extract the physical name of the terminal device 11, and controls this connection. The conversion control for notifying the means 5 is performed.

The correspondence table processing means 7 inputs a correspondence table processing request from any one of the terminal devices and arbitrarily changes the correspondence table shown in FIG. This gives a logical name
The correspondence between 41 and physical name 42 can be freely changed.

FIG. 5 shows an example of the correspondence table processing request.

This table processing request 40 includes a network management header, that is, a portion 43 indicating the destination, a command 44 indicating the processing request content to the correspondence table, a logical name 41, and a physical name.
It consists of 42 and. In this embodiment, the network management header destination 43 has the destination set to network management. This network management refers to the network management virtual terminal 4 shown in FIG. Therefore, the operator inputs the correspondence table processing request 40 from the terminal device 11 and is sent to the network management virtual terminal 4 to execute the table processing.

The command 44 of the table processing request 40 instructs the rewriting of the correspondence table of FIG. 4, and requests the terminal device 11 to rewrite the physical name 42 corresponding to the CC responsible officer of the logical name 41. .

By this request, for example, the terminal device 13 corresponds to the CC officer's seat having the original correspondence table contents, but the correspondence table processing request in FIG. 5 rewrites the correspondence table contents shown in FIG. That is, the terminal device 13 in FIG.
It is installed at the desk in charge of CC. However, the fifth
The correspondence table processing request shown in the figure has been rewritten so that the terminal device 11 is associated with the CC officer seat.

This means, for example, if the person in charge of managing the ATM20, which is one of the terminal devices shown in FIG. 1, is the person in charge of CC, this person in charge of CC is absent, and the management work is in charge of AA. This is based on the assumption that the officers will act on their behalf.

Under the above conditions, this network operates as follows.

FIG. 6 shows the connection request output by the ATM 20 (FIG. 1).

In FIG. 6, in the connection request 30, the destination 31 in the network management header is the CC officer, and the source 32 is the ATM2.
0, and the message 33 is "ATM voucher is empty"
That is the content. In this case, such a connection request from the terminal device (ATM) 20 shown in FIG.
When inputting, the name conversion means 6 refers to the correspondence table shown in FIG. 4 stored in the correspondence table storage means 8. Since the physical name 42 of the CC officer seat is the terminal device 11, the name conversion means 6 notifies the connection control means 5 to that effect. The connection control means 5 uses the result and outputs the message 33 (FIG. 6) of the terminal device (ATM) 20 to the terminal device 11. As a result, the content of the message shown in FIG. 6 is displayed on the display or the like of the terminal device 11. Therefore, even if the AA officer does not go to the place where the terminal device 13 is installed,
You can substitute the work of the CC staff. When the CC officer's office returns to work, the physical name corresponding to the CC officer's office is rewritten to become the terminal device 13 by using the correspondence table processing request as shown in FIG. 5 again.

Through the above processing, each terminal device can make a connection request by using a logical name without being aware of the physical name (physical address) of the connection destination. Therefore, even if the physical name itself is not changed, the position of the connection partner can be freely changed by a processing request of a simple correspondence table.

The present invention is not limited to the above embodiments.

The terminal device in which the present invention is implemented is not limited to such a management terminal device, and may be a terminal device used by an operator or the like to perform various accounting operations.
Further, with respect to the connection request when the host computer communicates with the terminal device, the above function may be used.

(Effects of the Invention) The network of the present invention described above uses a correspondence table that associates a physical name that identifies each terminal device with a logical name that indicates the role of each terminal device in the network. Since the connection request using the name is made possible, it is possible to extremely easily perform the work substitution when the person in charge is absent, switching when a failure occurs in a specific terminal device, and the like. Further, by using the logical name, it is possible to freely change the role division of each terminal device in the network at any time, and it is possible to meet various needs.
