FIG. 2 shows an example of the structure of the configuration information of the communication network 102 of the managed object, which is held in the management information database 105 in the network management device 101. As shown in the figure, managed objects belonging to the network are defined in a tree-like structure.

It has a root 201 at the top, and below it shows the entire logical network including a packet switch, PBX, multiplexer, etc. Packet switching network 202, PBX network 203

Here, n indicates that there are a plurality of objects to be managed.

On the other hand, the display device 103 generally takes a display form as shown in FIG. That is, the entire country of Japan is normally displayed (the topmost display is not limited), and the display 302 of district A of the national map 301 is displayed by the operation of the network operation manager.
The screen transitions as shown in the display 303 of district B. Furthermore, the display becomes progressively more detailed, from the A district display 302 to the A1 station display 304 and the A2 station display 305. Of course, a deeper level of display is also possible, and if a screen for displaying the internal configuration of communication devices such as TDMI and TDM2 is prepared in the display 304 of the A1 station, even more detailed parts can be displayed.

FIG. 4 is an example of the screen configuration display database 115 that the display device 103 has. A managed object 400 named "Pakistan" is a managed object corresponding to the national map 301 in FIG.
401 to correspond to the local map at the local level, and the managed object 401 "A region", etc., to the local map corresponding to the local level "A1 station" 402, "A3 station" 404 at the communication station level below it.
etc. are defined in a tree-like manner as shown in the figure. Further, for communication devices at a lower level, the structure of the management information database 105 shown in FIG. 2 can be used as is, as shown in the figure.

Next, before operation of the network management system to explain the configuration and operation of each part of the embodiment shown in FIG.
3, first, when operating the network management display processing system, the user on the display device 103 side uses the display presentation method setting unit 119 using the keyboard 120 to set the state values (management state values) of the components on the communication network configuration diagram displayed on the CRT 113. , operating status value, and alarm importance level), and stores the settings in the screen configuration/display database 115.

Next, an instance of each component is displayed as a communication network configuration diagram on the CPU 112 (in terms of the communication network configuration, an address name indicating whether the managed object belongs to a certain area, or (Internal system name convenient for identification)
The display data setting unit 118 associates the display identifier with the display identifier (a unique number within the system) and the screen configuration data (screen display coordinates), and the correspondence table between the display identifier and the screen display coordinates is created in the database. 115
A list of correspondence between display identifiers and instances is sent to the network management device. If the network management device 10'l directly transmits the instance of each component, there is no need to send this correspondence list. The operation of the network management device before operation of the information network system is shown.

First, the network management device 101 receives the correspondence list of the indicator identifier and the instance, and the display data setting/selection unit 108
Using the instance name as a key, the display identifier corresponding to the data field of the managed object having the corresponding instance name on the management information data table 501 as shown in FIG. 5 in the management information database 105 is stored. Next, the behavior of the network management device 101 during system operation of the information network management system will be described.

During system operation, the network management device 101 receives management information such as status information autonomously through the communication network 102 or transmitted by the management information collection unit 107 via the communication control unit 104, and stores it in the work memory 106. Next, the display data conversion/processing unit 109 searches the management information data table using the instance included in the status information as a key, and converts it into a display identifier. This results in
Display data consisting of the display identifier and the received status value is configured and transmitted to the display device 103 via the communication control unit 104.

The operation of the display device 103 during system operation is shown.

The display device 103 stores the received display data in the work memory 1.
16 is temporarily stored. Next, the screen conversion/display control section 117
The display coordinates (x, y) on the network configuration diagram are searched by using the display identifier and status value as keys to search the correspondence table of display identifier and display coordinates in the screen configuration display database 115, table for identifying the display color of the status, etc. , converts it into display color information corresponding to the status value, and displays the CRT1 according to this screen configuration data (drawing display coordinates, color) as shown in Figure @6.
13, the corresponding part of the communication network configuration drawing 601 (X, -'
J) Display the status at 602.

The above is a description of the display method based on autonomous management information notification from the communication fi 102.

Next, we will demonstrate the behavior when a network operator actively refers to the network configuration and various information. When a network operation manager wants to view detailed information of equipment that constitutes a communication station, such as 601 in FIG. (There are various possibilities such as, but not limited to here), a list display area 701 is secured on the communication network configuration diagram display screen 601 as shown in FIG. Can be of any size. It is also possible to separate the display bags. Here, displaying on the same screen is shown as an example.

Here, the request type of the display device 103 and the network management device 101 according to the request operation for displaying as a list is agreed upon in advance by the display presentation method setting section 119 and the display data setting/selection section 108, respectively.

When the network management device 101 receives a request to display a list of the internal device configuration from the display device 103, it displays the management information data table 50 using the instance of the component included in the request as a key.
1, and refer to and obtain its attribute information. After being stored in the work memory 106, the request response data is transmitted to the display device 103 via the communication control unit 104.

After issuing the request, the display device 103 sends the basic display frame data to the screen construction/display database 1 for list display.
15 and displayed by the screen conversion/display control unit 117. When receiving data from the network management device 101, it interprets the format of the received message and displays the necessary data in the list display frame in the list display area 701.

The list can be displayed not only in the internal configuration diagram as described above, but also at various levels such as "Japan 400, IIA region" 401 in FIG. In order to make this possible, a method is adopted in which the water increase of the display data trees shown in FIG. 4 is specified in the request data of the list display request from the display device 103 to the network management device 101.

As an example of displaying the list, Figure 8 shows the structure of the national map -vIi
801, ff19 Figure 2 A region (7) 4ff Sei R-
A list 901 is shown in FIG. 10, and a list 1001 of the constituent equipment of station A1 is shown in FIG.

- The list can be used not only to specify all the managed objects in a certain display screen as described above, but also to specify a single managed object and display the management attribute information of that managed object in a table format. There is also a way to reference and display it.

FIG. 11 shows an attribute information list 1101 of a certain managed object, for example, an individual device (here, a host computer).

An example of possible attribute information of a managed object is shown below. Logical relationship information between management and fish bodies is provided as attribute information to the management information table 501 stored in the management information database 105. For example, in the case of a computer network, this relationship information can be obtained from information on a processing procedure called generation when constructing a network system as a logical connection between a host computer and a terminal. In addition, the multiplexing device collects the network creation information, and the switchboard collects the information online if possible. When this management attribute information is supplemented to the management information database 105 of the network management device 101 and a display request is made from the input device 120 such as the keyboard of the display device 103, a certain management Display managed objects that have a logical relationship with the object. FIG. 12 is a display example of devices (terminals) logically connected to the host computer HO5TI.

Naturally, this display example is just one example, and the display format is not limited.

Furthermore, by tracing the relationship information of the managed objects, it is possible to derive the physical connection route between two managed objects that have a logical connection relationship. Everything related to communication, such as communication equipment hardware, transmission/reception ports, communication lines, O8I layer elements, etc., is defined as the managed object. Therefore, by tracing the relationship information of managed objects according to a certain rule, it is possible to derive a physical connection route between two managed objects. Regardless of how a network is defined, this law allows a physical connection path of only one line of a simple communication device to be obtained by tracing only the layer elements of the first layer of O5I, for example. In accordance with this rule, FIG. 13 displays physical connection paths for only communication equipment and lines.

Of course, this figure is just one example, and the display format is not limited.

The above is an example of displaying information on a single managed object or a list of a group of managed objects to which it belongs, at an arbitrary display level of management attribute information of managed objects constituting a management network.

Another example of using the management attribute information of a managed object is to define a management operation such as a test as a managed object, and store the attribute information in the management information database 1.
05, and also stores relationship information of a certain communication device with a managed object. When a display request is made from the input device 120 such as a keyboard of the display device 103, the information related to the managed object of a certain communication device is searched for through a processing method similar to the above system operation explanation, and can be executed on the managed object. You can display a list of administrative operations.

Next, the present invention will be explained using an example in which a critical situation such as a failure or performance deterioration occurs in a network.

The composition and operation of each part of the embodiment shown in FIG. 1 are almost the same. When the network management device 101 collects management information via the network communication control unit 104 and detects a failure from the instance and status information contained therein, the network management device 101 detects a failure in the HOST T as shown in FIG. The occurrence is indicated to the network management operator using a descriptive form. However, the management information data table 501 is searched using the instance and status information as keys, and display information is assembled and transmitted to the display device 103.

FIG. 15 shows an example of list information displayed when a failure occurs.

Here, we assemble information such as the location where the fault is detected, the actions that the network management operator should take depending on the extent of the fault, and emergency contact information, and display it! ! 103 and display it. Here, in the example above, the list information at the time of failure is assembled by the network management device 101, but the management information data includes instances, status information, processing to be taken by the network management operator, It is also possible to have a correspondence table of information such as emergency contacts on the display device 103.

FIG. 16 is an explanatory diagram of an information network management system equipped with an alarm device according to the present invention. Network management device 101
An alarm processing unit 1601 is provided inside the device, and an alarm device 1602 is provided as an external connection device.

Collect management information via the network communication control unit 104, search the management information data table 501 using instance and status information as keys, assemble display information, send it to the display device 103, and display it. The operation up to this point is the same as before. Here, the mesh pipe embedding [10
The tube shaft processing unit 1601 of 1 is the management information data table 50
1, extracts information such as emergency contact information using the instance and status information as keys, and instructs the alarm device 1602 to issue an alarm to the network management operator. Here, the alarm device 1602 is, for example, an alarm sound such as a buzzer, an automatic telephone device, a voice response device, etc., but it is sufficient if similar functions can be used.

[Effects of the Invention] According to the present invention, when displaying management attribute information of managed objects constituting a managed network on the screen, information on a single managed object or an arbitrary number of managed objects belonging to the network can be displayed. Groups are displayed in a list, management attribute information of managed objects is displayed at any display level,
Displaying information about a single managed object or any number of managed object groups to which it belongs, Displaying a list of management operations that can be performed on the managed object, Physical information of a certain managed object It is possible to display a list of physical connection partners and logical connection partners, and also to search and track relational attribute information of the physical connection route between a managed object and a managed object that has a logical connection relationship. By using ideographic shapes to display routes in sequence or in a table format, it becomes easier for network management operators to understand the status of the entire network, and efficient network management is always possible. It becomes possible.

In addition, when the performance of a managed object deteriorates or a failure occurs, the information stored in the management information database (1) that is necessary for the network operation administrator among the attribute information of the managed object, alarm information, etc. Alternatively, it can be displayed on a display device in a table format according to the request of the operation administrator, emergency contact information and troubleshooting methods can be immediately displayed on the display device for the network management operator, an alarm can be issued immediately, or the management information database can be referred to. It is equipped with functions for obtaining contact information and contacting network operation managers, maintenance personnel, etc., and the equipment necessary for these functions.

With these functions, network managers and maintainers can take appropriate actions even in critical network situations, reducing downtime and improving network reliability.
