Is done. However, such a network management method should be performed for each network target device and function that the operator wants to manage.

Existing network management systems often have similar types of screens and functions repeated for a large number of items. This requires a developer to repeatedly implement the same function as the number of items, which causes a problem of inefficiency in time and resources. For example, every time a function is implemented, a problem arises in that the screen, inquiry, and setting functions must be source coded. In addition, it is very inconvenient because all three sources must be compiled every time the source is modified.

Accordingly, the present invention is to solve the problems according to the prior art, an integrated that can manage the network equipment by using the menu XML file and the management function XML describing the management function of the nodes belonging to the menu. An object of the present invention is to provide a network management system and method thereof.

An integrated network management system according to an aspect of the present invention includes an XML parser unit for parsing a tree menu XML (eXtensible Markup Language) file describing a user menu and a control command XML file describing a function of the menu, and parsing the menu XML file. Graphical user interface unit for displaying a tree menu according to the result and receiving a network device parameter value when the operator selects the menu, and SNMP (Simple Network) for transmitting the received parameter value and the parsed control command to the corresponding network device. Management Protocol) communication unit.

In this case, the XML parser unit is an XML parsing module which is a class for parsing an XML file, an XML object conversion module for reading and converting the tree menu XML file into an XML node object, and storing attribute information of the object of the converted node. It can include an XML node module.

In addition, the graphical user interface unit generates a tree menu for each node of the tree menu XML file to configure an integrated management screen, and the operator selects the node and delivers the parameter values entered by the operator to the SNMP communication unit, the operator A row setting dialog module for receiving a parameter value for a network target device control command from a network, a tree storage module for storing a parameter value for the received network target device control command, and an integrated management main screen configured by the system management module It may include a tree display module.

More preferably, the SNMP communication unit receives a parameter value for a network control command from the graphical user interface unit SNMP control module for controlling to perform an SNMP command, MIB (Management Information Base) for performing the parameter value and control command An SNMP configuration storage module for storing information and an SNMP service module for performing communication according to SNMP using the parameter value and MIB information may be included.

The integrated network management method according to another aspect of the present invention includes parsing a tree menu XML file describing a user menu and a control command XML file describing a function of the menu, and displaying a tree menu according to the result of parsing the menu XML file. And receiving a network device parameter value when the operator selects a menu, and transmitting and controlling the received parameter value and the parsed control command to the corresponding network device.

In this case, the transmitting of the parameter value and the control command to the network device is characterized by using SNMP. The parsing of the tree menu XML file may include parsing the tree menu XML file to generate a class for each node and parsing the control command XML file to extract and store attribute information of the object of each node. It may include the step.

Hereinafter, an integrated network management system using XML according to the present invention and a method thereof will be described in detail with reference to the accompanying drawings.

2 is a flowchart illustrating a unified network management method according to an embodiment of the present invention.

The step S201 corresponds to a step of setting an inquiry and setting screen of a graphic user interface (GUI) of a network management client. In step S202, an operator writes a function to be implemented as an XML file. Hereinafter, an example of the XML file according to step S201 will be described.

3 is an exemplary view showing an example of a tree menu XML file according to another embodiment of the present invention.

Referring to the XML file of FIG. 3, items of a type name, a node name, a field name, and a file name can be seen.

In this case, the type name is an item for specifying the type of a network element (NE: network element) to be managed, and the node name is an item for setting a logical menu item of the tree menu. The field name is an item for setting the name of the management function to be added, and the file name is an item specifying the name of an XML file describing the management function to be added.

It can be seen that the tree menu XML file of FIG. 3 is for managing network equipment of the OG1200 type. Functions for managing the network equipment can be largely divided into two groups. One group is Generic Information and the other group is System Management.

Referring to the XML file of FIG. 3, generic functions and event management functions exist as functions belonging to the generic information group. Similarly, the functions belonging to the System Management group include the System Management function and the Security Management function.

In relation to the file name item, the XML file for the Generic Management function is generic_management.xml, and the XML file that describes the Event Management function is event_management.xml. In addition, the functions for System Management and Security Management are described in system_management.xml file and security_management.xml, respectively. Hereinafter, the control command XML file describing the functions to be implemented by the operator will be described.

4 is an exemplary view showing an example of a control command XML file according to another embodiment of the present invention.

The management function XML file of FIG. 4 includes a title value, a MIB value, an image value, an access value, a column ID value, and a column value. ), Column type, parameter name, and parameter value.

The title value means the title of the control command described in this XML file. This XML file describes Generic Management function in title value field.

The MIB field is a field that stores the MIB file name for the node that this XML file commands. The location where the MIB file that executes the command corresponding to this XML file is saved is "mibs / epon / SAMSUNG-EPON-COMMON-SOFTWARE-MANAGEMENT-MIB.my".

The image value is an item for setting an icon image indicating the network management function, and the access value is an item for selecting a parameter or data setting method of the network management function.

There is a set method or a create method as the data setting method. set is set when the network management system displays a previously stored value and receives a value to be changed from an operator. On the other hand, the create method is a method of setting parameters for a management function by newly inputting a value to be set by an operator.

The column ID value stores an MIB Object ID of a network management function to be operated. For example, if it has a column ID value with a value of .1.3.6.1.4.1.236.11.1.8.1.1.1.3.1.1, the network management system searches for the command corresponding to the value in the MIB server.

The column value is an item indicating a name to be displayed on the table of the integrated management screen. This column value is present in match with the column ID value. The column type is an item that sets the syntax type of the MIB node. The parameter name and the parameter value are set only when the column type is ENum. The parameter name and the parameter value store an integer value or a string value corresponding to a string.

7 is a flowchart illustrating a unified network management method according to another embodiment of the present invention.

In the integrated network management method according to the present invention, a step of editing an XML file for a menu of a user interface (S701) and an step of editing an XML file for storing network control commands are preceded (S702).

The integrated network management system parses the menu XML file edited in step S201 (S703). As a result of such a parsing operation, the integrated network management system generates a class in units of nodes (S704). In addition, the integrated network management system parses the network control command XML file of step S702 corresponding to the node and stores necessary attribute information (S705).

The integrated network management system displays the extracted node class and attribute information (S706). In addition, the integrated network management system detects an operation such as a double click from an operator to determine whether there is a request for changing a parameter value, adding or changing data (S707). This process is performed through the drawings of FIGS. 6A and 6B.

When the integrated network management system receives a new or modified parameter from the operator, the integrated network management system performs SNMP communication with the target network device by using the parameter value and the MIB information (S708). Now, data or commands received from the operator are delivered to the network device, and the network device may be managed according to the SNMP command (S709).

As described above, according to the integrated network management system and method using XML according to the present invention, it is possible to integrate and manage the network equipment by using the XML file, thereby providing a configuration management function that repeats similar screens and functions. In case of implementation, multiple source coding processes can be omitted, and data can be searched and controlled by network equipment through a single integrated screen, and thus the operator can easily control the network.
