## Background
CLAIM OF PRIORITY
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application for STANDARD PLATFORM OF NETWORK EQUIPMENTS AND METHOD FOR USING THEREOF earlier filed in the Korean Industrial Property Office on Mar. 14, 2002 and there duly assigned Serial No. 2002-13853.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a platform for a network technology group, and more particularly, to a standard platform for a network technology group having a common software element, a common module, applied easily to various technology groups, such as a synchronous digital hierarchy SDH, a plesiochronous digital hierarchy PDH, an asynchronous transfer mode ATM, an internet protocol IP, a voice over packet VoP, an inverse multiplexing over asynchronous transfer mode IMA, or a digital subscriber line and its variations xDSL.
2. Description of the Related Art
Generally, a software system in a network technology group embodies and maintains a hierarchical signal and a protocol defined by an international standard such as Management Information Base MIB.
However, the hierarchical signal and the protocol are various according to the kind of the software system in the network technology group. Therefore, even though the network technology group is the same, an applied hierarchical signal and an applied protocol can be different. As a result, the standard hierarchical signal and the standard protocol defined by the international standard such as MIB are used in congestion, even though the same software system, platform, is applied to the same kind of a network technology group.
FIG. 1 is a configuration of a software system installed in each of the technology groups.
Referring to FIG. 1, to construct a network under surroundings of XXX software system (platform), the software system is applied to the kind of the technology groups, for example, XXX ATM, XXX SDH, XXX IP, XXX xDSL, etc. Additionally, to construct a network under surroundings of YYY software system (platform), the software system is applied to the kind of the technology groups, for example YYY ATM, YYY SDH, YYY IP, YYY xDSL, etc. In the same way, to construct a network under surroundings of ZZZ software system (platform), the software systems are applied to the kind of the technology groups, for example ZZZ ATM, ZZZ SDH, ZZZ IP, ZZZ xDSL, etc.
Therefore, a system developer has to develop a software system according to the kind of a predetermined technology group to be applied to new platform because a standard and common software system does not exist for the predetermined technology group.
As a result, the conventional network technology group has the following problems because a software system is applied to the predetermined technology group, while a system-dependent software element is not distinguished from system-independent software element.
At first, because the software system for the predetermined technology group is embodied by the intuition of a system developer, it is limited to develop or maintain the software system in the predetermined technology group according to modification of the system platform.
Secondly, because the conventional software system is developed by a system developer-oriented method, various software systems are maintained in a platform according to the various technology groups.
Thirdly, it is difficult to install the conventional software system used in a technology group to other technology groups because the technology groups vary.
Finally, development resources are duplicated and development time is delayed, because common software is not shared among various technology groups.
SUMMARY OF THE INVENTION
To overcome the above described and other problems, preferred embodiments of the present invention provide a standard platform for a network technology group and application method thereof having a library, a module, by separating a system-independent software system from a system-dependent software system so as to be installed easily to various technology groups.

The common field, maxIndex, of the management element is 1 when the single management element contains a single physical port; the common field, maxIndex, of the management element is more than 1 when the single management element contains multiple physical ports; and the structure and the procedure method within the management element can be changed according to the value in the common field, maxIndex.
The API controls the function block, the management group, or the management element; and the API performs a function of creating, deleting, registering, searching, setting, or monitoring the function block, the management group, or the management element.
The common module is provided as a profile structure to assist the creating function of the API.
The profile structure includes necessary data for generating a corresponding element, and is provided as a header file to the user of the common module.

To isolate a system-independent software element from a system-dependent software element within the above described large classified technology group, the technology group is divided into several functional blocks, and those functional blocks generate a minimum common element of the technology group, a library (a module).
FIG. 3 is a block diagram illustrating function blocks of each technology group isolated to embody a software system according to the present invention.
Referring to FIG. 3, the technology group SDH includes function blocks, such as SPI, RST, MST, MSP, MSA, HPOM, PPC, HPT, HPA, LPC, LPT, LPA, or PPI, and the technology group ATM includes function blocks, such as AAL1, AAL2, AAL3, AAL5, VCA, VCC, VCLT, VCT, VPA, VPC, VPLT, or VPT.
The functional blocks for the technology groups IP, xDSL, PDH, or IMA are the same block illustrated in FIG. 3, and a detail explanation for the functional blocks will be omitted.
The role of each function block for the technology group ATM is described in the following statement.

    
    
        1. AAL5/AAL3/AAL2/AAL1 (Asynchronous transfer mode Adaption Layer 5, 3, 2 and 1, respectively): These layers convert an ATM Adaption block, an ATM cell, to the corresponding message such as an IP packet or an X.25 packet.

        9. TP/VPA (Transmission Path/Virtual Path Adaption): TP/VP application block.
    
    


As described in the above statement, the function blocks in each technology group are generated for each function, such as a message change function or a connection process function.
FIG. 4 is a diagram illustrating a hierarchy of a common module in each technology group for embodying a software system according to the present invention.
Referring to FIG. 4, a function block includes a hierarchical management group as a sub-structure, and the management group is divided by according to roles within the function block, such as fault, configuration, account, performance, security reliability, test, or clock group. The management group has a different shape and size according to technology groups and function blocks.
The management group includes more than one management element as a sub-structure. The management element is the minimum unit of a common module in a technology group, and is classified differently according to the corresponding management group.
In this case, API controls each of the function blocks, the management groups, and the management elements.
The API includes a creation function, a deletion function, a registration function, a getting function a setting function, and a monitoring function. The creation function generates a function block, a management group and a management element, and the deletion function deletes the function block, the management group and the management element. The registration function registers a callback function of a linked list structure to the function block, the management group and the management element, the getting function searches contents of the function block, the management group and the management element, and the setting function defines the contents of the function block, the management group and the management element. In addition, the monitoring function performs a function-defined process by using the contents of the function block, the management group and the management element, and performs appropriate procedures relative to the results thereof.
To assist the creation function, the common module provides a profile structure. The profile structure, provided as a header file to a system developer, contains necessary data in generating a corresponding element of the common module.
The management element is the minimum unit in the common module of the technology group, and contains actual structure contents. Even though it has a different structure according to the characteristic of the management group, the management element includes common fields as illustrated in the following statements.
To assist the creation function, the common module provides a profile structure. The profile structure provided as a header file to a system developer contains necessary data in generating a corresponding element of the common module.
The management element is the minimum unit in the common module of the technology group, and contains actual structure contents. Even though having different structure according to the characteristic of the management group, the management element includes common fields as illustrated in the following statements.
One of the common fields, meterID (meter identifier), is an identifier of the management element determined through the profile or the API by a system developer for the common module of the technology group.
Another common field, usagePrv (usage previous), is a value for determining whether the manage element is used or not, and is determined through the profile or the API by the system developer for the common module of the technology group.
Additionally, another common field, maxIndex (maximum index), is a value for determining whether a single management element contains a single physical port or not. For example, when the common field, maxIndex, is 1, then the single management element contains a single physical port. When the common field, maxIndex, is more than 1, then the single management element contains multiple physical ports. The structure and the procedure method within the management element can be changed according to the value in the common field, maxIndex. The common field, maxIndex, is determined through the profile and the API by the system developer for the common module of the technology group.
According to the above described conditions, among the profile structure corresponding to the common module, the structure of a fault management element is illustrated in FIG. 5A, the structure of a performance management element is illustrated in FIG. 5B, the structure of a test management element is illustrated in FIG. 5C, and the structure of a clock management element is illustrated in FIG. 5D.
When a system developer develops a new platform by using the above described common module of the technology group, the following procedure will be performed.
At first, it is necessary to construct a software build, including a common module corresponding to a technology group or a function block contained logically in a constructing system.
Secondly, a profile structure relative to the corresponding function block, such as FIG. 5A to FIG. 5D, is provided through a header file, set to fit the constructing system, and generated through a generation API.
Finally, a defined function is performed by calling a performing function API periodically, and a user searches or changes the set-value through the getting/setting API when requested by the user.
As described in the above statements, the standard platform embodying method for a network technology group according to the present invention provides the following effects.
At first, it is easy to develop a module for new network technology group when a user provides information required for the new technology group as a profile.
Secondly, a library, a module, is embodied according to the kind of technology group. Therefore, when it is necessary to include a technology group related to the existing network, a library corresponding to the technology group is only applied. As a result, unnecessary parts are eliminated so as to guarantee efficient re-usage, and to minimize the size of software programs.
Finally, a trace module and a memory module independent from any other technology group can be applied to any technology group, and can be easily tested in the case of adding new technology group.
