Abstract

PURPOSE: A managed object searching method using a managed object registration list is provided to simplify the construction of a real resource interface module only with a list management and message comparison function, improve a processing rate and improve reliability of a system by omitting an additional maintenance and repairing process. CONSTITUTION: When a monitoring control message is received from a network factor(601), a rack number of a message received from a rack layer of a managed object registration list is checked(602) to check whether the message rack number and the list rack number are identical to each other(603). If the two numbers are identical, a self number of a message received from a self-layer of the managed object registration list is checked by using a down pointer(604) to check whether the message self number and the list self number are identical to each other(605). If a list fact that the message rack number and the list rack number are identical is not searched, the message is disregarded and a monitoring control message is again received(601). If the message self number and the list self number are identical, a board number of a message received from a board layer of the managed object registration list is checked(606) to check whether the message board number and the list board number are identical to each other(607). If the two numbers are identical, the message is transmitted to all managed objects connected to a pointer of the board(608).

Description

Managed Object Searching Method Using Managed Object Registration List

The present invention provides a management object using a management object registration list for searching for a management object corresponding to a component that generated a message in order to transmit a message received from a network element to a corresponding management object in a real resource interface module between the management agent and the network element. It is about a search method.

FIG. 1 is a diagram illustrating a conventional software block configuration for searching a management object. In the drawing, "11" represents a management object, "12" represents a real resource interface, and "13" represents a network element.

The telecommunications management network consists of managers and management agents.

The management agent sends alerts and performance data generated from network elements to the manager through the Common Management Information Protocol (CMIP) interface.

The manager analyzes the alarm and performance data received from the management agent to identify the status of the network element and maintains the alarm.

The real resource interface module 12 analyzes the contents of the monitoring control message received from the network element 13 to identify the fault component 131 of the network element 13 where the message is generated, and models the fault component 131. The failure management object 111 is identified and the message is transmitted to the failure management object 111 corresponding to the failure component 131.

The management agent models all the components 131 and 132 of the network element 13 as the management object 11 to monitor and control received from the network element 13 when an alarm occurs in the network element 13 or a performance parameter changes. The message is analyzed and recorded in the failure management object 111 corresponding to the failure component 131 of the failed network element 13 and reported to the manager. At this time, the alert and performance message received from the network element 13 is transmitted to the failure management object 111 modeling the failure component 131 of the network element 13 that generated the message.

Looking at such a conventional management object search method is as follows (see Figure 2).

First, when a monitoring control message is received from the network element 13 (201), the real resource interface module 12 is a failure component for the rack, self, and board type of the network element 13 included in the received message ( 131) Analyze the location information (202), and analyze the alarm type for the communication alarm, the performance alarm, and the device alarm (203).

Thereafter, the cause of failure is analyzed to determine a failure management object 111 to which a message is transmitted (205).

In this case, a plurality of management objects 11 may be selected for one message, and the real resource interface module 12 transmits a message received from the network element 13 to all of the determined management objects 11 ( 206, 207).

As described above, the search method of the management object by analyzing the message includes a real resource interface module that analyzes the monitoring control message and finds the management object when a new kind of management object is added or the physical configuration of the network element changes. 12) there was a problem that needs to be changed.

In order to solve the problems described above, the present invention does not determine a management object to receive a message by analyzing a monitoring control message, and the management object becomes a subject of a real resource interface to perform a real resource interface function of a management agent. Its purpose is to provide a managed object search method using a managed object registration list.

31: Management Object

32: network element

According to an aspect of the present invention, there is provided a management object searching method comprising: a first step of registering information on a position of a component in a network element to be managed together with a name of the management object in a management object registration list; A second step of, when the monitoring control message is received from the network element, comparing the location information of the component in the message with the information registered in the management object registration list; And a third step of transmitting a message to the corresponding management object in which the information registered in the management object registration list and the component position information of the network element match.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is an exemplary view showing a software block configuration for searching a managed object to which the present invention is applied. This does not determine the management object to receive the message by analyzing the monitoring control message, the management object 31 is the subject of the real resource interface to function as the real resource interface of the management agent.

Each management object 31 first registers information on the position of the component 322 of the network element 32 to be managed by the management object registration list 313 together with the name of the management object 31. When the monitoring control message is received from the network element 32, the location information of the component A 321 of the network element 32 included in the message is registered in the management object registration list 313 without analyzing the content of the message. The monitoring control message is transmitted to the management object 311 in which the component A 321 location information is matched with the contents.

All management objects 31, which indicate the status of network elements and report failure and performance information to the administrator, may provide information on the location of the components 321 and 322 of the network element 32 to be managed at the time of initial creation. It registers in the management object registration list 313 with the name of 31). At this time, the list registration information includes the rack number, the self number, the board number, and the name of the management object of the component. At this time, a structural diagram showing an example of the management object registration list 313 is shown in FIG.

When a new management object 31 is created, the management object 31 registers its real resource interface information in the management object registration list 313.

As shown in FIG. 4, the management object registration list 313 includes a rack layer, a self layer, a board layer, and a management object layer.

In the rack hierarchy, there is one list element 401 for each rack.

In the self hierarchy, there is one list element 402 for each shelf included in the rack.

In the board layer, one list element 403 and 404 exists for each board included in each shelf.

Therefore, one network element consists of several racks, one rack consists of several shelves, one shelf consists of several boards, and one board consists of several management objects connected by links. do.

There are two pointers to each of the list elements for rack, shelf, and board, one representing another list element (a through d) that is the same hierarchy as itself, and the other representing the first element of its lower hierarchy list ( e to g).

For example, if the management object A 311 is a management object for the rack 2, the self 1, and the board 3 of the network element 32, the management object registration list 313 when the first creation, the rack 2, It registers that it is a management object 31 for self 1 and board 3.

Find Rack 2 (401) in the Rack hierarchy, Find Shelf (402) in the Self hierarchy, find Board 3 (404) in the board hierarchy, and find the list of managed objects belonging to the down pointer of Board 3 (404). At the end, add the managed object 406 name.

If a failure occurs in rack 2, shelf 1, and board 3, the network element 32 transmits a supervisory control message to the real resource interface module 312, and the real resource interface module 312 sends the rack 2, self Names of the management objects 405 and 406 belonging to the first and the third boards are found in the management object registration list 313 to transmit a message to the management object A 311.

5 is a flowchart illustrating an embodiment of a method for registering a management object registration list according to the present invention.

First, a list element matching a rack number to which it belongs is searched for in a rack hierarchy (501).

Then, it is checked whether there is a rack in the rack hierarchy that matches its rack (502).

If there is no matching rack, add a list element for the new rack using its rack number (503), and if it finds a matching rack, use the down pointer (e) of the rack to find the first shelf belonging to the rack. Search the list element 402 (504).

Next, the self hierarchy checks whether there is a shelf that matches its shelf (505).

If there is no matching shelf, add a list element for the new shelf using your own shelf number (506) .If you find a matching shelf, use the downward pointer (f) of the shelf to find the first board belonging to the shelf. The list element 403 is searched for (507).

Thereafter, the board layer checks whether there is a board that matches its own board (508).

If there is no matching board, add the list element for the new board by using its own board number (509), and if it finds a matching board, use the down pointer (h) of the board to register the list of managed objects belonging to the board ( In step 313, the name of the last managed object is added.

6 is a flowchart illustrating an embodiment of a method for searching for a managed object according to the present invention.

First, when a monitoring control message is received from the network element 32 (601), by checking the rack number of the message received in the rack layer of the management object registration list 313 (602) message rack number and list rack number match Check whether it is (603).

If the message rack number and the list rack number match, the self-number of messages received from the self-layer of the management object registration list 313 is examined using the down pointer e (604), and the message self number and list self number are checked. Check if 605 matches (605).

On the other hand, if the message rack number and the list rack number does not match the list element is found, the message is ignored and receives the monitoring control message again (601).

If the message self number and the list self number match, the board number of the received message is checked in the board layer of the management object registration list 313 to check whether the message board number and the list board number match (607).

As a result of the check, when the received message board number and the list board number match, the message is transmitted to all management objects 31 connected to the pointer of the board (608).

On the other hand, if a list element in which the message self number and the list self number match is not found, and the list element in which the message board number and the list board number match are not found, the message is ignored and a monitoring control message is received again (601).

When the management object is deleted, the management object deletes the management object registration information registered just before the management object is deleted from the management object registration list 313 so that the message is not transmitted to the management object that does not exist.

According to the present invention as described above, the management object 31 becomes a subject of the real resource interface and functions as a real resource interface function of the management agent, thereby not analyzing the monitoring control message in the real resource interface module 312, and monitoring control message. It is not necessary to change the real resource interface module 312 even if is added or changed. In addition, the management object registration information is organized into a list to effectively use the memory, and all the management objects on one board are connected by a link, which has the advantage of finding all management objects to transmit a message in one search.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

According to the present invention as described above, the configuration of the real resource interface module is simplified only by the list management and message comparison function, the processing speed is faster, and a separate maintenance process is omitted, thereby improving the reliability of the system.
