Abstract

The present invention relates to a remote network element management method, and more particularly, to a method of improving alarm information processing speed when collecting alarm information generated in a network element. When a failure occurs in a network element managed by a network management device, an alarm is generated. When an alarm occurs, an administrator collects the generated alarm information, stores it in a database, and inquires the stored alarm information. At this time, as the DB storage process is performed as many times as the DB storage count, the client can display the slot representative alarm of each slot in the client only after processing as many as the DB storage count, thereby delaying the processing time for the alarm display. The present invention is characterized by processing the representative alarm by having a structure that is reported to include a representative alarm of the shelf and slot in one alarm information. Accordingly, the time and work required for alarm processing when receiving alarms from the management target can be shortened to improve the data processing performance of the network management device. It is possible to improve the reliability of the.

The present invention relates to a remote network element management method, and more particularly, to a method of improving alarm information processing speed when collecting alarm information generated in a network element. When a failure occurs in a network element managed by a network management device, an alarm is generated. When an alarm occurs, an administrator collects the generated alarm information, stores it in a database, and inquires the stored alarm information. In this case, the present invention is characterized by processing the representative alarm by having a structure that is reported to include the representative alarm of the shelf and slot in one alarm information.                         

The representative alarm refers to an alarm having the highest grade among the corresponding shelf alarms and slot alarms. In other words, failure level such as critical, major, and minor are assigned according to the degree of failure, and the representative alarm is the highest priority among failures, that is, the alarm with the highest failure level. .

In addition to the alarm information, the alarm information reported from the network element includes a shelf representative alarm and a slot representative alarm for synchronizing an alarm signal between the network management device and the management target, and a rectifier shelf representative alarm and rectifier slot when there is a rectifier shelf. Representative alarms are included and the information is stored in the respective DB tables.

That is, the alarm information is stored in the database alarm table, the shelf representative alarm is in the shelf table, the representative alarm in each slot is in the slot table, the rectifier shelf representative alarm is in the direct shelf table, and the representative alarm in each rectifier slot is the direct slot. Stored in a table.

Meanwhile, an example of a DB table structure according to the prior art is as follows.

First, an example of the shelf DB table structure is as follows.

typedef struct

{

    int network_id;

    int subnetwork_id;

    int ne_id;                         

    int rack_id;

    int shelf_id;

    char shelf_name [20 + 1];

    char alias [20 + 1];

    int type;

    int loc_in_rack;

    int loc_in_shelf;

    int shelf_mode;

    int east_shelf_id;

    int west_shelf_id;

    int up_shelf_id;

    int rect_state_on_off;

    int rid;

    int sid;

    int cid;

    int lid;

    int shelf_vpi;

    int alarm; / * Save Shelf's representative alarm * /

    int oper_state;

    int xcoord;                         

    int ycoord;

    char location_info [LOCATION_INFO_LEN + 1];

    int iftype;

} shelf_table;

In the shelf table structure, a representative alarm of a shelf is stored in an integer variable of 'alarm'.

An example of a slot DB table structure is as follows.

typedef struct

{

    int network_id;

    int subnetwork_id;

    int ne_id;

    int rack_id;

    int shelf_id;

    int slot_id;

    char slot_name [20 + 1];

    int unit_type;

    int equip_type;

    int alarm; / * Save the representative alarm of the slot * /                         

    int equip_state;

    int oper_state;

    char hwversion [20 + 1];

    char swversion [20 + 1];

    int rear_equip_state;

    int a_mls;

    int switch_type;

    int loop_state;

    int prot_grp_info;

    int rdl_state;

    int port_num;

} slot_table;

In the slot table structure, an integer 'alarm' variable stores a representative alarm of a slot.

1 is a flowchart illustrating an alarm information processing according to the prior art. As shown in the figure, when alarm information is collected first (S1), the alarm information is stored in a database in the server and recorded in a DB alarm table (S2). In the next step, the shelf representative alarm of the alarm occurrence shelf is stored and recorded in the shelf table of the DB (S3).

 In the next step, the slot representative alarm is stored in the slot table of the DB in the slot table for the individual slot in the shelf (S4). At this time, the slot representative alarm for all the individual slots is stored in the slot table. To this end, the process in which the slot representative alarm is stored in the slot table of the DB is repeated by the number of slots (S5).

If there is a rectifier shelf, the direct shelf representative alarm is stored and recorded in the direct shelf table of the DB according to the same method (S6). The representative alarm is recorded in the direct slot table of the DB (S7). To this end, the process in which the direct slot representative alarm is stored in the direct slot table of the DB is repeated by the number of the direct slots (S8).

2 is a DB storing method of alarm information according to the prior art. As shown

In the related art, a representative alarm of a slot is stored in a DB table of a corresponding slot, and the number of times alarm information is stored in the DB when one alarm occurs depends on the number of slots that can be mounted in the shelf.

FIG. 2 illustrates the case of having a shelf and a direct shelf. The shelf and the direct shelf have 21 slots and 7 slots, respectively. Therefore, to save the alarm in DB, 31 save procedures including 1 alarm information, 2 shelf and direct shelf alarm information, 21 slot and 7 slot alarm information are executed. That is to say, in general terms, the following relationship holds.

DB Save Count (n ') = Alarm Information + Shelf Representative Alarm + Representative Slot of Each Slot (n)

In other words, when a failure occurs, the alarm information is first recorded in the DB. Then, the shelf representative alarm of the failed shelf is recorded in the DB. Finally, each slot representative alarm for each slot in the failed shelf is recorded in the DB. In this case, since each representative alarm for each slot is recorded in the DB, the DB information is stored as many as the slot number n in addition to the alarm information and the shelf representative alarm. Therefore, as the DB storage process is performed by the DB storage frequency (n '), the client can display the slot representative alarm of the individual slot only after the DB storage frequency (n') is processed. There is a problem that the processing time for the delay.

The present invention is to solve the above-mentioned problems, the shelf alarm of the shelf and all the slot alarms in the shelf can be processed by a single DB storage to consume a lot of time during the data processing process in the network management device It aims to increase the performance and management capacity of the network management device by reducing the number of DB storage, which is a hard disk I / O process.

In order to achieve this object, the present invention has a client and server structure for monitoring a network element as a basic structure, and includes a database for storing and managing information related to a failure.

The management capacity of the network management device is determined by the amount of data received and the processing speed of the data. In view of the fact that most of the received information is alarm information, the improvement of the alarm processing speed improves the performance and management capacity of the network management device. This is directly related to improvement.

Therefore, in the prior art, the present invention is to store the number of slots per alarm or more in the DB to solve the phenomenon in which data processing delay occurs when an alarm is congested or a certain number of managed objects are managed. Representative alarms of all slots belonging to are managed in an array in the shelf table so that the representative alarms of the shelf and the representative alarms of all slots in the shelf can be processed as a single DB storage. Accordingly, the number of DB storages, which is a hard disk I / O process that consumes a lot of time during data processing in the network management device, can be reduced, thereby improving performance of the network management device and increasing management capacity.

 In other words, in the prior art, when the shelf table adds a column of slot alarm arrays as many slots as the shelf can accommodate, the slot representative alarm information is sequentially inserted into the slot alarm array, and then the shelf table is stored. When the alarm occurred, the shelf representative alarm was stored in the shelf table and the slot representative alarm in each slot table. However, the present invention is characterized by processing by storing only the arrangement of the shelf table.                     

Accordingly, the number of DB storages, which is the hard disk I / O process that consumes the most time during data processing in the network management device, can be significantly reduced. In addition, in the prior art, the client of the network management device is configured to read the slot representative alarm from each slot table by periodically polling the representative alarm information of the slot, but the present invention provides a shelf representative alarm even when only the arrangement of the shelf table is read. And the representative alarm of the slots set in the shelf can be seen to reduce the traffic load (client traffic) between the client (server).

3 is an alarm information processing flowchart according to the present invention.

The server of the network element management system receives the alarm information reported from the management target (s1), processes the alarm information and stores it in the alarm table of the DB in the server (s2). After saving the alarm information, the server reads the shelf representative alarm into the alarm array of the shelf table, reads the slot representative alarm into the slot alarm array (slot_alarm []), and stores the shelf table in the DB (s3). If there is a direct shelf, the server reads the direct shelf representative alarm into the alarm array of the direct shelf table and reads the direct slot representative alarm into the direct slot alarm array (rect slot_alarm []). Store the table in the DB (s4).

Meanwhile, the client periodically reads the slot alarm array slot_alarm [] of the shelf table from the DB to perform representative alarm processing of slots in the shelf viewer. Data periodically updated by the client is constantly displayed so that the user can monitor the data. Regarding the direct slot alarm arrangement (rect slot_alarm []), representative alarm processing of the direct slots is performed according to the same method as described above.

4 is a diagram illustrating a DB storage method of alarm information according to the present invention. As shown in FIG. 2, unlike the prior art according to FIG. 2, the storage method of the alarm information according to the present invention has a direct shelf as the slot alarm information is recorded in the shelf table. In all cases, all three storage procedures are completed. The above process describes all the processes stored in the DB, and the process can be referred to as performing a procedure on the server side.

In this case, the procedure for the case of displaying alarm information to the client also follows the same technical idea as described above. That is, in the prior art, when the information in the slot table is to be shown to the client, the procedure of reading the individual slot information as many as the number of individual slots 21 is repeated. However, in the present invention, the slot information is recorded together in the shelf table. According to this, the alarm information of the shelf and the slot can be shown to the client with only one procedure.

Meanwhile, an example of a shelf table which is a DB table according to the present invention is as follows.

typedef struct

{

    int network_id;

    int subnetwork_id;

    int ne_id;                     

    int rack_id;

    int shelf_id;

    char shelf_name [20 + 1];

    char alias [20 + 1];

    int type;

    int loc_in_rack;

    int loc_in_shelf;

    int shelf_mode;

    int east_shelf_id;

    int west_shelf_id;

    int up_shelf_id;

    int rect_state_on_off;

    int rid;

    int sid;

    int cid;

    int lid;

    int shelf_vpi;

    int alarm;

    int oper_state;

    int xcoord;                     

    int ycoord;

    char location_info [LOCATION_INFO_LEN + 1];

    int iftype;

    char slot_alarm [number of slots + 1];

} shelf_table;

In the shelf table structure, the representative alarm of the shelf is stored in the variable 'alarm' of the interger type as before. The variable 'slot_alarm [number of slots + 1]' of the character type is an added part according to the present invention. In this arrangement, representative alarms of individual slots are stored. According to the program, the alarm structure of the slot alarm table is represented in the shelf structure.

The technical spirit of the present invention has been described above with reference to the accompanying drawings. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.

According to the present invention, the data processing performance of the network management device is improved by shortening the time and work required for alarm processing when an alarm is received from the management object, thereby eliminating data lag even during data congestion, thereby improving the stability of the network management device. The reliability of the management device was improved.
