Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a network management control system for managing, for example, a communication device connected to a communication network.

[0002]

2. Description of the Related Art As is well known, in a conventional network management control system, various communication devices to be managed (for example, exchange devices such as a key telephone device and a PBX) are:
As shown in FIG. 9, the management is controlled by a management device CS1 such as a workstation existing on the same LAN or a management device CS2 through a wide area network.

[0003] The management devices CS1 and CS2 are
Access the management information storage unit of the communication device as necessary,
It performs operations such as reading data and setting data.

FIG. 10 shows a configuration of a conventional communication device to be managed (hereinafter, referred to as a device to be managed). In addition,
Here, the configuration mainly related to management control will be schematically shown.

The device to be managed includes a plurality of management information storage units 10a to 10d for storing various parameters such as control data of the device to be managed, and a read control unit 2 connected to the management information storage units 10a to 10d.
0 and a write control unit 30 and a network management protocol control unit 40.

[0006] Network management protocol control unit 40
Communicates with devices on a network according to a predetermined protocol. For example, the aforementioned management device C
When communicating with S1 (or CS2) and receiving a data setting instruction and its setting data, the instruction and the setting data are input to the write control unit 30. On the contrary,
The write control unit 30 stores data obtained through the network management protocol control unit 40 in the management information storage units 10a to 10a.
d is sequentially recorded.

The network management protocol control unit 40 communicates with the management device CS1 (or CS2), receives a data read request, and reads the data.
To the management information storage unit 1
The data is read out from 0a to 10d, and the read-back data is transmitted to the management device CS1 (or CS2).

Here, referring to FIGS. 11 and 12,
The update control operation of the data setting of the management target device will be described.

First, referring to FIG. 11, an example of successful data update will be described. The management device CS1 (also in CS2) manages data through the read control unit 20 and the network management protocol control unit 40 (both not shown). The data (a, b, c, d) stored in the information storage units 10a to 10d are read out and temporarily stored in the storage unit M of the own device.

Thereafter, the management device CS1 sends the management information storage units 10a to 10a through the network management protocol control unit 40 and the write control unit 30 (both not shown).
Data d is sequentially rewritten into data (A, B, C, D).

At this time, the management target device sequentially verifies whether there is any inconsistency or defect between the data to be rewritten, and if there is no such problem, accepts the data rewriting request from the management device CS1 and Is updated and rewritten to data (A, B, C, D).

Next, referring to FIG. 12, a description will be given of a failure example of data update. First, as described above, the management device CS1 (the same applies to the CS2) transmits data (a) stored in the management information storage units 10a to 10d through the read control unit 20 and the network management protocol control unit 40 (both not shown). , B, c, d) are read out and temporarily recorded in the storage unit M of the own device.

Thereafter, the management device CS1 sends the management information storage units 10a to 10a through the network management protocol control unit 40 and the write control unit 30 (both not shown).
Data d is sequentially rewritten into data (A, B, C, Dx).

At this time, the management target device refuses to update the data if there is an inconsistency or a defect between the sequentially rewritten data. In this case, the management device CS1 stops updating the data (A, B, C, Dx) and returns to the previous data (a, b, c, d) stored in the storage unit M again. Implement control to update.

As described above, in the conventional network management control system, since a plurality of data recorded in the device to be managed are related to each other, there is a contradiction or a problem between newly input data at the time of updating. It is necessary to return the data updated so far to the state before the update again.

This includes management devices CS1 and CS2
In addition, there is a problem that not only a storage unit M for storing data before updating is required, but also software implementation is complicated.

[0017]

In a conventional network management control system, when data recorded in a device to be managed is updated, if there is a contradiction or a problem between newly input data, the updated data is updated. Must be restored to the state before the update. This not only complicates the implementation of the software required for update control,
There is a problem that a storage unit for storing data before update is required.

The present invention has been made to solve the above-mentioned problem, and does not require a storage unit for storing data before updating, and can perform data updating control with a simple software implementation. It is an object to provide a simple network management control system.

[0019]

To achieve the above object, the present invention provides a network management control system in which a management device manages a communication device connected to a communication network through the communication network. A data verification unit that verifies whether or not a plurality of data can be recorded in a storage unit of the own device; and a data verification unit that verifies a plurality of data when a request for recording a plurality of data from the management device to the storage unit is issued. The data is input to the means for verification, and as a result, when all the data can be recorded, a recording control means for recording a plurality of data in the storage means is provided.

In the network management control system having the above configuration, before recording a plurality of data in the storage means, it is verified whether or not the data can be recorded, and only when all the data can be recorded, the plurality of data are stored in the storage means. To be recorded.

Therefore, according to the network management control system having the above-described configuration, a data storage unit for storing data before update is not required for updating data in the storage means, and simple software is used. Data update control can be performed by implementing the software.
