The present invention relates to a network management system that is a package for managing terminal devices constituting a network. More specifically, the activation information for collecting performance statistics of a network management system and activation information for collecting performance statistics of a terminal device may be matched. A network management system that can be.

Network management system functions are divided into terminal device management, configuration management, connection management, performance management, and fault management. This is defined as a service that enables customers to maintain their virtual networks more efficiently. However, in performing such a service, there may be a case where the performance statistics activation information of the network management system does not match the performance statistics activation information of the terminal device. For example, when a failure of a network or a terminal device occurs, the performance statistics collection activation information of the network management system and the performance statistics collection activation information of the terminal device may be inconsistent with each other. In the case of the existing network management system, there is a mechanism for instructing the deactivation of performance statistics collection in another network management system or in the event of a terminal device failure, the performance statistics collection is automatically deactivated and the information transmitted to the network management system. However, when a mismatch between the performance statistics collection activation information of the network management system and the performance statistics activation information of the terminal device occurs in the case of a network or terminal device failure, there is no mechanism to solve this problem.

In this regard, a process performed to collect performance statistics in a conventional network management system is performed as follows. First, a user logs in to a network management client of a network management system using a web browser, and then issues a collection activation command for performance statistics data that the user wants to view. The command is delivered to the network management server through a communication interface according to the inter-object communication interface standard such as the Common Object Request Broker Architecture (CORBA). The network management server receiving the collection activation command transmits the performance statistics collection activation command to the corresponding terminal device through the communication interface between objects. The terminal device activates the collection of performance statistics for the corresponding performance item, and if the activation is successful, transmits the result to the network management server, and the network management server stores the information in a table of a database that stores the performance statistics activation information.

If the performance statistics collection activated by the network management system is deactivated by other network management systems, or the performance statistics collection is disabled due to a failure in the terminal device, this is CORBA's IIOP (Internet Inter-ORB). It is reported in the form of an event to the network management system using a protocol such as Protocol. However, if there is a network failure or a failure in which the above mechanism cannot be executed in the terminal device, performance statistics collection activation information between the network management database and the terminal device must be inconsistent with each other.

As can be seen from the above, the conventional network management system does not have a mechanism for solving the inconsistency of the performance statistics collection activation information due to network or terminal device failure. Therefore, there is a need for a system that can solve the problem and provide instantaneous and reliable by matching the performance statistics activation information in the event of network failure or terminal device failure.

The present invention activates performance statistics collection using a web browser, and then, if a performance statistics collection activation information of a database of a network management system and a performance statistics collection activation information of a terminal device are inconsistent at a specific time, It is an object of the present invention to provide a network management system that can synchronize performance statistics collection activation information of a database with performance statistics collection activation information of a terminal device by issuing a synchronization command using a browser.

In addition, when a synchronization command of performance statistics activation information is simply given to the system using a communication mechanism between the network management client, the network management server, and the terminal device, the terminal device receives the command and records the performance statistics activation information in a file for each performance type. And parsing the file to a network management server's database to resolve the discrepancy between the performance statistics collection activation information of the database and the performance statistics collection activation information of the terminal device. The purpose.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to various embodiments of the present invention for achieving the above object.

The network management system according to an embodiment includes a network management client and a network management server, and these components manage the network by communicating through an object-to-object communication interface with terminal devices configuring the network. For example, the communication interface conforms to the CORBA communication interface standard, and may perform IIOP communication using a CORBA library. In addition, a DBMS (Database Management System) for managing a database may be installed in the network management server.

In one embodiment, the network management client provides a user interface (Graphical User Interface, etc.) that allows a user to issue a synchronization command of performance statistics collection activation information, and the network management server is configured to provide performance statistics collection activation information of the network management client. The role of transmitting the synchronization command to the terminal device and the activation statistics collection activation information are reflected in the database. The terminal device reports the performance statistics collection activation information to a network management server in a file.

1 is a schematic diagram illustrating a network management system 10 using a performance statistics data collection mechanism according to one embodiment. The network management client 11 illustrated in FIG. 1 includes a user interface provided to a user who manages a terminal device constituting a network, and the network management server 12 requests a network management client. It serves as a bridge for transmitting to the terminal device 20, and inserts and deletes the performance statistics collection activation information into the database (13). Meanwhile, the terminal device 20 receives a request from the network management server 12, collects performance statistics activation information, stores it as a file, and reports it to the network management server 12. CORBA, which is used as the communication interface 30 between the network management system 10 and the terminal device 20, is a type of communication interface standard between objects for realizing a distributed entity system. The database 13 of the network management server 12 may be implemented as a database using a database management system such as an Oracle DBMS or Informix DBMS.

A process of collecting performance statistics data according to the conventional performance statistics data collection mechanism shown in FIG. 1 will be described below.

First, when the network management client 11 issues a performance statistics collection activation command, the network management server 12 transmits the command to the terminal device 20. After receiving the corresponding command, the terminal device 20 starts to collect performance data and transmits a success message to the network management server 12. When the network management server 12 receives the success message, the network management server 12 reflects it in the STATACTINFO table of the database 13.

On the other hand, the terminal device 20 makes the data in the internal memory 21 into a file at regular time intervals, and then transmits the file information to the network management server 12 so that the network management server 12 takes the file. . The network management server 12 receives the file, parses the data, and inserts the data into the database 13.

FIG. 2 is a diagram illustrating a network management system using a mechanism for responding to a failure of a terminal device or an event of deactivating performance statistics collection by a system other than the corresponding network management system. The response process is outlined as follows.

When the network management client 11 activates performance statistics data collection, a process according to the mechanism of FIG. 1 may be performed.

Meanwhile, when the performance statistics collection deactivation event occurs in the terminal device 20, it is transmitted to the network management server 12. The network management server 12 reflects the corresponding event in the STATACTINFO table of the database 13 and reports it to the network management client 11.

In the case of using such a mechanism, when a network failure occurs or a failure in which the terminal device cannot execute the above mechanism may occur, the network management database and the performance statistics collection activation information of the terminal device may be inconsistent with each other. Therefore, by performing the mechanism described below, it is possible to prevent the inconsistency between the performance database collection activation information of the management database and the terminal device.

3 illustrates a mechanism for responding when a network failure or other failure occurs and communication between the network management server and the terminal device is lost, according to an embodiment. If this is outlined as follows.

First, the network management client 11 issues a synchronization command of the performance statistics collection activation information, and the network management server 12 transmits it to the terminal device 20. Meanwhile, the terminal device 20 reads performance statistics collection activation information from the internal memory 21 into a file, and transfers the information about the file to the network management server 12.

The network management server 12 receives the file from the terminal device 20, parses the data, and then reflects the performance statistics collection activation information in the STATACTINFO table of the database 13.

Hereinafter, more specific embodiments will be described with respect to operations performed in each of the network management system and the terminal device. Various functions used in the embodiments to be described below are described on the assumption that a general CORBA programming tool based on the Java platform is used.

First, the network management client 11 calls the syncPmStatInfo () function set to indicate a synchronization command of performance statistics collection activation information as follows.

result syncPmStatInfo (string nodeName)

The network management server 12 calls the corresponding function through CORBA IIOP, and the function also calls the syncPmStatInfo () function in the terminal device 20 through the CORBA IIOP. When the function of the terminal device 20 is called, the function creates a file in a predetermined format. For example, a unique ID of the terminal device 20, board and port information of the terminal device, a virtual path identifier (VPI) and a virtual circuit identifier (VCI) of the Asynchronous Transfer Mode (ATM), and performance statistics types. If you need information such as performance statistics data collection interval and whether performance statistics data collection is enabled, create a file in the following format.

'SystemId: BoardId: PortId: AtmVPI: AtmVCI: StatType: StatPeriod: StatActInfo'

The statistics at the port level of the terminal device 20 create a file in the following format.

'SystemId: BoardId: PortId: StatType: StatPeriod: StatActInfo'

For interface statistics, create a file in the following format:

'SystemId: BoardId: PortId: InterfaceName: StatType: StatPeriod: StatActInfo'

The terminal device 20 transmits the following information (data structure) to the network management server 12.

struct StatActInfo {

    string SystemId;

    string fileLocation;

    string fileName;

    string auxInfo;

 };

The network management server 12 parses the above file and inserts the same into the database 13. The database schema is as follows.

CREATE TABLE STATACTINFO (

    SYSTEMID VARCHAR2 (20) DEFAULT NULL,

    BOARDID NUMBER DEFAULT NULL,

    PORTID NUMBER DEFAULT NULL,

    VPI NUMBER DEFAULT NULL,

    VCI NUMBER DEFAULT NULL,

    IFNAME VARCHAR2 (20) DEFAULT NULL,

    STATTYPE NUMBER DEFAULT NULL,

    STATPERIOD NUMBER DEFAULT NULL,

    ACTFLAG NUMBER DEFAULT NULL

 );

Based on the above configuration, the following describes a process for synchronizing performance statistics collection activation information.

First, a user issues a synchronization command of performance statistics collection activation information through a user interface screen in a network management client. Accordingly, the syncPmStatInfo () function is called from the network management client, and the syncPmStatInfo () function of the network management client calls the syncPmStatInfo () function existing in the network management server using IIOP communication using CORBA. Meanwhile, the syncPmStatInfo () function of the network management server calls the syncPmStatInfo () function in the terminal device by using IIOP communication using CORBA.

The terminal device reads the performance statistics collection activation information from the memory in the terminal device and accumulates the strings of the above-described format one by one in a predetermined file. In addition, the terminal device accumulates all the statistics activation information in the file and delivers the information on the file to the network management server through IIOP communication using CORBA through the reportPerfInfo () function.

The network management server reads information on a file transferred from a terminal device and retrieves a file from the terminal device through a Trivial File Transfer Protocol (TFTP) library. In addition, the network management server opens a file imported from the terminal device, reads each line, parses the data into a database table, and then deletes all statistical activation information on the terminal device before storing the table in the database. do. The network management server also inserts the performance statistics collection activation information into the database, and then generates an event to update all the screens of users displaying the user interface.

Although the above embodiments have been described on the assumption that a general CORBA programming tool based on the Java platform is used, a project using the CORBA tool may be applied by applying the system disclosed herein.

According to the above embodiments, when a network failure occurs or a problem occurs in another terminal device or network management server, the performance statistics collection activation information managed by the network management server and the performance statistics collection activation information managed by the terminal device are inconsistent. The performance statistics data is continuously collected at the terminal device and reported to the network management server, but the network management server may not manage the data. On the contrary, the performance management data is continuously managed even though the performance statistics data is not collected at the terminal device. This can prevent errors.

In addition, by manually matching the performance statistics collection activation information managed by the terminal device with the performance statistics collection activation information managed by the network management server, the user can trust the performance statistics collection activation information managed by the network management server under any circumstances. Ensure it is guaranteed.

In addition, according to the above embodiments, the performance statistics collection activation information managed by the terminal device and the performance statistics collection management managed by the network management server more stably by using IIOP communication of CORBA for communication between the network management server and the terminal device. You can match the information.
