Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] This invention relates to a method for creating information within a network by a network monitoring device that monitors a network consisting of a plurality of stations.

The purpose of the network monitoring device is to enable the network monitoring device to quickly respond to changes in the station configuration of the stations that make up the network and create accurate network information. Each station is periodically inquired about its station configuration, and in response to this station configuration inquiry, each station returns its own station configuration as response information to the network monitoring device, and the network monitoring device responds to the response information from each station. Based on this information, a database regarding the station configuration is created, and based on this database, inquiries are made to each station regarding the state of the station configuration, thereby creating network information.

[Industrial Application Field] The present invention relates to a method for creating network information using a network monitoring device that monitors a network consisting of a plurality of stations.

As this type of monitoring system, for example, a system is known in which a network monitoring device monitors and displays the status of a packet switch that constitutes a packet switching network (for example, the status of its installed equipment and the status of an accommodation line).

In this system, a network monitoring device sends a command to each switching center to request the transmission of the normal/abnormal status of each switching center's equipment and lines, and in response to this command, each switching center sends its own status information. The information is sent back to the network monitoring device, and the network monitoring device thereby creates network information to grasp and display the status of the entire network.

Such a system needs to be able to quickly respond to changes in the configuration of each station in the network and accurately monitor the network status in near real time.

[Prior Art] Conventionally, in a system in which a network monitoring device is connected to a packet switching network consisting of packet switching centers, for example, the network monitoring device monitors the station configuration of each packet switching center (the implementation state of various devices and the capacity of lines). It has a fixed database of information regarding the location, etc.), and based on this database, it sends various makeshift commands (for example, commands to inquire about the normality/abnormality of the installed equipment and accommodation line) to each exchange regarding the station configuration. Created and transmitted, each exchange responds to this timing command and sends a response message regarding the status of its own station configuration (normal/abnormal status of mounted equipment and accommodation lines, etc.) to the network monitoring equipment. However, this allows the network monitoring device to create a database of network information that allows it to grasp the status of the entire network.

That is, FIG. 8 shows a network that performs the conventional method of creating a line information database for a network monitoring device. In the figure, 11 is a network monitoring device, 12
．． 13 and 14 are packet switching stations, and the network monitoring device 11 has databases for stations 12, 13, and 14, respectively. Of these databases, the data regarding the station configuration is prepared in advance and is fixed. For example, regarding station 13, the station configuration information such as that line X is accommodated and devices Y and Z are installed is fixed. provided.

In such a conventional monitoring system, for example, as shown in FIG.
When creating a database regarding the station configuration status of No. 3 (normality/abnormality of installed equipment and accommodated lines), the network monitoring device 11 refers to the database regarding the station configuration of station 13 that it has in its own device, and determines whether station 13 accommodates line X. And equipment Y
, Z, and creates a timing command to inquire about the normal/abnormal status of the line X and devices Y and Z to the station 13, and sends it.

When the station 13 receives this timing command, it edits data regarding the status of its own equipment and line, creates a response message, and sends it back to the network monitoring device 11. In the example shown in FIG. 9, this response message contains data indicating that line X is normal and devices Y and Z are abnormal.

As a result, the network monitoring device 11 can have the status of the station configuration of the station 13 as a database, and by performing the same operation for the stations 12 and 14, it is possible to create network information indicating the status of the entire network. I can do it.

[Problems to be Solved by the Invention] In the conventional network monitoring system, each station 12, 13, 14 and the network monitoring device 11 have information regarding the network station configuration separately, and the network monitoring device 11 has information regarding the network station configuration separately. The network monitoring device 11 creates and sends timing commands to each station based on the database it has, and collects information on the station configuration status of each station. The content is

For this reason, for example, as shown in FIG. 10, the station 13 has the following information: When jIW is added and the station configuration is changed to lines x and W and devices Y and Z, the contents of the database will be changed in the station 13 due to the addition of lines, but on the network monitoring device 11 side, the database is fixed. Since it is a
Even if 3 lines are added, it will not be updated automatically.

Therefore, the station configuration information for station 13 is queried based on the previous database, but in this case,
Since no arrangement is made for the extension line W, the status of the extension line W cannot be monitored.

In this way, conventional network monitoring systems have the problem of not being able to accurately understand and monitor the network status unless the database of the station configuration of the network monitoring device is always the same for each station in the network to be monitored. be.

In addition, as a method to match the database regarding the station configuration of each station in the network and the network monitoring device, when there is a change in the number of lines or equipment on one station side, the database regarding the station configuration of the network monitoring device can be updated in accordance with this change. One possible method is to manually change the database, but in this case, it takes a lot of man-hours to change the database, and there is a risk that errors in the process may cause data inconsistencies between stations and monitoring equipment.

Furthermore, it is generally difficult to change the databases on the station side and the network monitoring device side at the same time, and this causes problems such as a time lag in the consistency of the databases on the station side and the network monitoring device side.

The present invention has been made in view of the above-mentioned technical problems, and its purpose is to enable a network monitoring device to monitor changes even when there is a change in the station configuration of the stations that make up the network. The goal is to be able to respond quickly and create accurate network information.

[Means to solve the problem] FIGS. 1 and 2 are explanatory diagrams of the principle of the present invention.

In one embodiment of the method for creating network information of a network monitoring device according to the present invention, as shown in FIG.
~53 is inquired about its station configuration, and each station 51~5
3 returns the station configuration of its own station as response information to the network monitoring device 54 in response to this station configuration inquiry, and the network monitoring device 54 creates a database 55 regarding the station configuration based on the response information from each of the stations 51 to 53. Based on this database 55, it is configured to inquire of each of the stations 51 to 53 about the state of the station configuration to create network information.

Further, as another form of the method for creating network information of a network monitoring device according to the present invention, as shown in FIG.
1 to 53 about the station configuration and the status of the station configuration, and each station 511 to 53 simultaneously returns the station configuration and the status of the station configuration as response information to the network monitoring device 54 according to this arrangement, Network monitoring device 54
is configured to create network information regarding the station configuration and the state of the station configuration based on the response information from each of the stations 51 to 53.

[Operation J] In the method for creating network information in the form shown in FIG. 1, the network monitoring device 54
The station configuration information of No. 3 is not fixed, but only the minimum station information such as where to send the timing command is stored, and based on this station information, the information is sent to each station 51 to 53. Inquiries regarding the station configuration are periodically made, and a database 55 regarding the station configuration of each station 51 to 53 is created based on the response information. As a result, even if there is a change in the station configuration of each of the stations 51 to 53, the database regarding the station configuration will be updated sequentially through periodic inquiries.

The network monitoring device creates and transmits an adjustment command regarding the station configuration status of each station 51 to 53 based on this database regarding the station configuration that is updated sequentially. In response to this station configuration state adjustment command, each of the stations 51 to 53 sends the station configuration state of its own station back to the network monitoring device 54 as response information. As a result, the network monitoring device 5
4, even if there is a change in the station configuration of the stations 51 to 53 in the network, it is possible to quickly respond to this change and accurately grasp the state of the network.

In the method for creating network information in the form of FIG. 2, as in the case of the above-mentioned form, the network monitoring device 54 does not have station configuration information of the stations 51 to 153 in the network in a fixed manner. The station should have only the minimum information on where to send the message.

Based on this station information, the network monitoring device
1 to 53 are periodically and simultaneously inquired regarding the station configuration and the station configuration status. Each station 51 to 53 returns its own station configuration and its station configuration state as response information to the network monitoring device 54 in accordance with this timing. This allows the network monitoring device 54 to
Even if there is a change in the station configuration in 53, it is possible to quickly respond to the change and accurately grasp the state of the network.

【Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 3 shows a network monitoring system for a packet-switched network using a method for creating information within a network as an embodiment of the present invention. In FIG. 3, 1 is a network monitoring device, and 2, 3, and 4 are packet switching stations to be monitored.

The network monitoring device 1 sends device/line station configuration information (for example, the mounting status of various devices or the line accommodation position, etc.) to all stations of each switching center 2, 3. A function to send a time adjustment command to inquire about the station configuration information) and a function to rewrite the station configuration database held in the own device according to the response results from each exchange 2.3.4 to this station configuration inquiry command. and,
It has the function of monitoring and displaying the equipment/line status of each exchange according to the database held in its own equipment.

In addition, this network monitoring device does not have fixed station configuration information as a database regarding each station 2.3.4, and as fixed data, it sends timing commands to which stations when collecting information in the network. I only have station information that tells me what to do.

That is, FIG. 3 shows the contents of the databases of the packet switching center 2.3.4 and the network monitoring device 1 in the initial state.
has the station information of exchanges 2.3.4 as the destination station information, but these stations 2.3.
The station configuration information regarding the configuration of No. 4 is not held as fixed data and is blank. This station configuration information is
As will be described later, this is variable data that is updated sequentially as data is collected.

On the other hand, each station 2.3.4 in the network refers to the database regarding its own station configuration and its status, and the own station database for the station configuration and station configuration status adjustment commands from the network monitoring device 1. The network monitoring device 1 has a function of sending the information back to the network monitoring device 1. That is, as shown in FIG. 3, it holds data regarding the equipment/line status within its own station, and the content of this data is that the exchange 2 has lines/equipment X and Y, and this line/equipment X. , Y are both normal, exchange 3 is X as line/device,
Switching center 4 has X and Y as lines/equipment, of which lines/equipment x and z are in a normal state and line/equipment Y is in an abnormal state. It is assumed that line/device Y is in an abnormal state.

The operation of this embodiment scheme will be explained below.

First, as shown in FIG. 4, the network monitoring device 1 creates a station configuration inquiry command for each exchange 2.3.4 to inquire about the equipment and line configuration of each station based on the station information database. and sends this to the appropriate exchange.

When each exchange 2.3, 4 receives this station configuration inquiry command, it refers to its own database, edits data regarding the station configuration of its own devices and lines, and creates a response message. This is sent back to the network monitoring device l. The contents of this response message are that station 2 has lines/equipment X and Y as its station configuration, and station 3 has lines/devices X and Y as its station configuration; ! /Has devices x, y, and z as a station configuration, and station 4 has line/device X
, Y as the station configuration.

The network monitoring device 1 receives response messages from each exchange 2.3.4, and creates a database regarding the configuration of each exchange 2.3, 4 based on the received response messages.

This station configuration adjustment sequence is performed at startup of the network monitoring device I and periodically thereafter. This period may be a period at regular intervals or a period at random intervals. As a result, if there is a change in the station configuration of each exchange 2.3.4 and its database changes, the station configuration database on the network monitoring device 1 side will be rewritten at the above inquiry cycle. , it becomes possible to quickly respond to changes in station configuration.

Furthermore, in order to monitor the normal/abnormal state of the station configuration of each switching center 2, 3.4 in the network, the network monitoring device 1 has a system for each switching center 2.3 maintained in its own device, as shown in FIG. A station configuration state adjustment command that inquires about the status of the station configuration is created based on the database regarding the station configuration in .4, and is sent to each exchange 2.3.4.

In response to this timing command, each exchange 2.3.4 checks the station configuration status regarding the normal/abnormal status of its own lines and equipment based on its own station database, and uses this information as a response message to monitor the network. Return to device 1.

As a result, the network monitoring device 1 writes the contents of these response messages into the database regarding the station configuration status of each station 2.3.4, and displays the status according to these contents if necessary.

If network information is created in the network monitoring device 1 as described above, each exchange 2.
3.4 Even if there is an increase or decrease in the number of lines or devices, the contents of the database of the network monitoring device 1 can be changed quickly in response to this, and this situation is shown in Figure 6. .

That is, in FIG. 6, it is assumed that the station configuration of switching center 3 initially consisted of lines a and b and devices A and B, and that this station configuration was later changed to a station in which line tdAc was added and device B was reduced. It is assumed that the configuration has been changed.

In this case, the network configuration database regarding the exchange 3 of the network monitoring device 1 initially has contents of times 1diia, b and devices A and B, but the station configuration inquiry periodically made to the exchange 3 As a result, this surface configuration database corresponds to the station configuration of exchange 3, times,! a,
b, c, and device A, and therefore, the station configuration state adjustment made to exchange 3 is related to the normal/abnormal status of these lines a, b, c and device A, and the exchange The station 3 returns response messages regarding the station configuration status, so that the network monitoring device 1 can immediately know the status regarding the newly added line C.

In this way, in the embodiment system, even if there is a change in the station configuration on the network side, the surface configuration database on the network monitoring device side is automatically changed based on periodic adjustments from the network monitoring device. When changing the station configuration of a network, it is now possible to do so without having to manually change the database of the network monitoring device, and the information after the network change is automatically reflected in the network monitoring device after a certain period of time. The status will now be displayed.

Furthermore, according to the system of this embodiment, when installing a program/data for network monitoring into a network monitoring device of a network at the time of system startup, the network monitoring device has a fixed configuration of the device/line configuration of the network in advance. Since there is no need to register it as a configuration database, when performing initial installation on network monitoring devices of various types of networks with different device/line configurations, it is possible to use common programs/data for all networks. This makes it possible to reduce the unique adjustment work required for each individual network, as well as the on-site installation work.

Various modifications are possible in implementing the invention. For example, in the above embodiment, the network monitoring device adjusts the station configuration for each station and its station configuration state as separate sequences, but the present invention is not limited to this. It is also possible to make inquiries about the station configuration status and the station configuration status in the same sequence.

FIG. 7 shows a sequence diagram of another embodiment of the present invention using the same sequence. In this example,
Each exchange 2.3.4 is configured to add status information about the station configuration information of the device/line as well as the station configuration information of the device/line to the scheduling command from the network monitoring device 1, and send it back to the network monitoring device 1. ing.

In the example shown in FIG. 7, initially, the station configurations of stations 2 and 3 are both lines x, y, and devices X, Y. After that, line Z is added to station 2, and device It shows how the database on the network monitoring device l side is changed when there is a change in .

As shown in FIG.
Inquire about the station configuration and status of the device/line at the same time, and in response, receive notification from station 2 of the station configuration and its status information (line x, y” normal, device X = abnormal, device Y = normal). , this is held as a database for station 2. The same thing is done for station 3, and a database for station 3 is created and held.

If line 2 is added to station 2, response information including information about line Z is sent from station 2 to network monitoring apparatus 1, depending on the station configuration of network monitoring device L and its status. As a result, the data "time m z = normal" is added to the database of the station 2 on the network monitoring device 1 side, and the database is updated in accordance with the addition of the line 2.

Similarly, when device X of station 3 is reduced, the database of network monitoring device l regarding station 3 is updated, and the data regarding device X is reduced.

In addition, in one or more embodiments, the explanation has been made assuming that the target to be monitored by the network monitoring device 1 is a packet switching center.
Of course, the present invention is not limited to this, and it is clear that the present invention is applicable to various communication stations having equipment to be monitored.

[Effects of the Invention] According to the present invention, even if there is a change in the configuration of a network station, such as adding or removing equipment or lines, the changes can be automatically and quickly reflected in the database of the network monitoring device. This eliminates the need to manually rewrite the data page of the network monitoring device in response to network changes, which not only reduces work man-hours, but also prevents data matching between the monitoring device and the station due to a single work error, or data matching. It is possible to avoid the occurrence of a time delay until the process is completed. This makes it possible to accurately monitor the network status in near real-time in response to changes in the network station configuration.

Further, according to the present invention, there is no need to fixedly register data regarding the station configuration of each station of the network in the network monitoring device, so that data can be initially installed in network monitoring devices of various types of networks. When connecting network monitoring devices, there is no need to change the data of each station inside the network monitoring device, and therefore, network monitoring services can be provided using common standard software. Coordination work that depends on the network will be reduced.
