Description

Automatic method of setting network address when creating network element in network management system

The present invention relates to a method for automatically setting a network address when generating a network element (NE) in a network management system (NMS). In particular, when a network topology is configured in a FLC-C management system (FLC-C) of the optical subscriber transmitter (FLC-C), if a network element of the FLC-C is added, the network element detects it. A method for automatically setting a network service access point (NSAP) address.

In general, a network address setting function that performs a predetermined function should associate with each network element when the FMS is initially installed. However, to establish a connection, a network address must be set for each network element. The network addresses are the transport selector (TSEL), presentation selector (PSEL), session selector (SSELector: SSEL), and NSAP addresses. These addresses are normally entered manually by opening the setting screen.

1 is a flowchart illustrating a conventional network address setting. First, open the FMS Object Configuration Tools (OCT) screen to set the network address (4). The operator directly enters the TSEL, PSEL, SSEL and NSAP addresses (6). The inputted address is transmitted to the host digital terminal (HDT) and the optical network unit (ONU) of the optical subscriber transmitter (8). The transmitted network address is checked by the FMS (10), and the network element information is displayed on the network topology display screen of the FMS configuration management according to the set network address (12).

Examples of TSEL, PSEL, SSEL and NSAP addresses are as follows: "TSEL: 0x5053, PSEL: 0x5353, SSEL: 0x5354, NSAP: 0x39410F800000000000000000004CC038FFFFF01". As shown in the example, TSEL, PSEL, SSEL and NSAP have a problem of being very difficult and complicated for the operator to input.

A common implementation method for easy operation is to implement the input window by using a graphical user interface (GUI), but such an implementation is only an improvement of the input method. Therefore, it is still necessary to enter complex numbers and characters, and the meaning is also composed of a combination of numbers, so there are many mistakes due to typos.

Accordingly, the present invention was devised to solve the above problems, and in setting up the NSAP address automatically so that the user can easily connect with the network element in supporting the FLC-C network topology configuration in the FMS. It is an object of the present invention to provide a method for automatically setting an address.

The above and other objects and novel features of the present invention will become more apparent from the following detailed description of the invention and the accompanying drawings.

In the network management system according to the present invention devised to achieve the above object, a preferred embodiment of the automatic network address setting method when generating a network element is

And displaying the retrieved network element as an icon on the network map topology display screen of the FMS configuration management.

In the present invention, the process of automatically setting the network address by inputting ASCII characters instead of the corresponding address,

Reading the cmipAgent.cfg file to establish a connection with the default agent at boot time;

Inputting a human readable ASCII character instead of the address;

Automatically changing the system to code that the system knows about;

Inserting the changed code into the address; And

It is preferable to include the step of storing the inserted code in a database,

Preferably, the read cmipAgent.cfg file contains TSEL, PSEL, SSEL and NSAP addresses indicating the setting state of the common management information protocol of the agent.

inputting tid;

Inputting a default value to a variable having a fixed value;

Reading one character of the tid;

Checking whether the read character is null and setting a corresponding variable;

Outputting 10 variables having a fixed value and a converted value as a 2-character hexadecimal string; And

It is preferable to further include a step of generating a total of 20 characters NSAP address by concatenating the 10 output strings in sequence,

After reading the tid character and setting the variable,

Reading the next character of the tid;

Checking whether the character is null and setting a corresponding variable; And

Preferably, the method further comprises the step of reading the next character of the tid,

By repeating the above steps, it is desirable to set a total of eight variable values.

The process of checking whether the character is null and performing the variable,

If it is not null, storing the read character in the variable by ASCII conversion method; And

If null, it is preferable to include the process of setting the variable to the specified default value.

The ASCII conversion method,

Converting uppercase letters to uppercase letters;

The process of converting 'A' to 'Z' from 1 to 26; And

'0' to '9' is preferably a process of converting from 32 to 41.

In order to establish a connection between the FMS and the HDT / ONU of the FLC-C, the TSEL, PSEL, SSEL and NSAP addresses must be input. In the present invention, the shell script (UNIX) is executed while the FMS is booted, and the FLC- The address of the C system (the above four) is automatically found and set up so that the user does not have to enter a complicated address separately. In addition, in case a problem occurs during a search and the address cannot be entered, an input window that can be input manually is provided by implementing a GUI.

In this way, even if a network element is added, the network element is automatically added to the FMS screen, so the operator does not need to perform additional work to establish a connection with the network element.

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

2 is a flowchart illustrating a method for automatically setting a network address according to the present invention.

First, the FMS object configuration tool (OCT) is driven to set the network address (24).

In order to establish an association with the default agent at boot time, the cmipAgent.cfg file containing the configuration state of the common management information protocol (CMIP) of the agent is read (26). The contents of the file read contain TSEL, PSEL, SSEL and NSAP addresses. If the user enters human-readable ASCII characters in place of the address (28), the system automatically knows the code (for example, "TSEL: 0x5053. PSEL: 0x5353. SSEL: 0x5354. NSAP: 0x39410F800000000000000000004CC038FFFFF01"). Change to ") to insert an address (30). The inserted code is stored in a database, and when the inputted address is transmitted to the host digital terminal (HDT) and the optical network unit (ONU) of the optical subscriber transmission device as in the prior art (32), the transmitted network address is transmitted from the FMS. In operation 34, the network element found on the network map topology display screen of the FMS configuration management is displayed as an icon.

3 is a detailed flowchart illustrating an automatic network address setting method.

First, a tid (tuple identifier) is input (42). After inputting a default value to a variable with a fixed value (44), one character of tid is read (46).

It checks whether the read character is null (48), if not null, converts the read character to ASCII and stores it in the corresponding variable (50). If null, sets the variable to the specified default value (52). If the variable is set, the next character of tid is read (54). If the read character is null (56), if not null, the read character is converted to ASCII and stored in the corresponding variable (58). If null, the variable is set to the specified default value (60). Again read the next character in tid. Repeat this process to set a total of eight variable values.

Ten variables having fixed values and converted values are output as two-character hexadecimal strings (62). A total of 20 characters of NSAP address are generated by concatenating 10 output strings in sequence (64).

The aforementioned ASCII conversion method is as follows. If the alphabet is lowercase, convert it to uppercase and convert 'A' to 'Z' from 1 to 26, and the numbers '0' to '9' from 32 to 41.
