ASN.1/GDMO is the management object used in network management of TMN(Telecommunication Management of Network). However, ASN.1/GDMO is not directly used for managing the network, but translated Into a language with object-oriented paradigm. Therefore we need a development environment for handling ASN.1/GDMO. In this paper we present an integrated development environment(IDE) which consists of an editor and a browser. A user manages ASN.1/GDMO elements with GUI. The IDE is implemented with FLEX and BYACC in UNIX. And Objectivity DB is used as the DB and Tcl/Tk is used for developing GUI. This paper shows how the integrated environment of ASN.1 and GDMO works, and that it enables to manage efficiently the network.

The management of network in TMN defines and manages the objects which are the operating system and communication equipments in network. GDMO is used to describe thoseobjects. GDMO is not directly used for managing network, but translated into a language with object-oriented paradigm. This paper presents design and implementation of the translator which automatically translates the specification of GDMO to the object-oriented language for generating MIB(Managment Information Base). And the system includes various graphic use interface to enhance the development environment of GDMO.

본 논문에서는 실제 자원의 개발 전에도 망 관리 시스템의 개발 및 운용 테스트를 수행하도록 지원하는 실제 자인 시뮬레이터(RRS: Real Resource Simulator)를 위해 확장된 GDMO 문법과 이를 처리하는 I-GDMO 컴파일러를 소개한다. RRS에서는 사용자가 원하는 형태로 실제 자원의 동작을 시뮬레이션 해야 하므로, 기존 GDMO의 패키지 부분에 사용자가 동작 특성을 기술 할 수 있도록 문법을 확장하였다. 또한 I-GDMO 컴파일러는 기존의 GDMO 컴파일러 역할과 RRS의 구성 요소 중 사용자가 정의한 동작 특성을 유지하는 SDT(Simulation Rata Table)의 내용을 초기화하는 역할을 동시에 수행한다.

The management of network in TMN(Telecommunication Management Network) defines and manages the objects which are the operating system and communication equipments in network. The GDMO(Guideline Definition Managed Object) is used to describe those objects. GDMO is not directly used for managing network, but translated language into a language with object-oriented paradigm, then which is used. This paper presents design and implementation of the translator which automatically translates the specification of GDMO to the object-oriented language for generating MIB. And the system includes various graphic user interface to advance the development environment of GDMO.

Network management in TMN concerns to the operating system and communication equipments in network, and defines them as objects. GDMO(guidelines for the Definition of Managed Objects) is used to describe those objects. GDMO is not directly used for managing the network, but translated into a language with object-oriented paradigm. And GDMO refers to ASN.1(Abstract Syntax Notation One) for manage objects. This paper presents design and implementation techniques for the translator which automatically translates the specification of ASN.1 and GDMO to the object-oriented language for generating MIB(Managed object Instance Base). This system, unlike the existing source code generator, is designed to generate various object-oriented languages automatically, which are used to generate Managed object Instance Base(MIB). And the system includes various graphic user interface to enhance the development environment of ASn.1 and GDMO

The agent system for managing various equipments constituting communication networks is usually started to be developed after completing real resources or can be developed using network management platform independent from real resources. In this paper, we design real resource simulator which can perform in advance the function of real resources without real resources. The real resource simulator performs the role of automatically generating specific attribute value and informing it according to the specified random function. Moreover, in this paper, we design E-GDMO grammar in which the grammar for simulation is added to the existing GDMO grammar and its E-GDMO compiler to perform real resource simulator.

실제 자원과 이에 대한 에이전트의 개발이 완료되기 전에는 망 관리시스템의 개발과 운용이 어려운 문제점을 해결하기 위한 방안으로 망 관리 시스템을 위한 테스트베드를 이용하는 방법이 있다. 이러한 테스트베드를 이용하기 위해선 사용자가 실제 자원의 동작을 반영하는 관리 객체의 속성과 통고에 대한 데이터를 조정할 수 있어야 하는데, 그중 하나의 방법이 기존의 관리 객체에 대한 기술을 지원하는 GDMO(Guidelines for Definition of Managed Objects)를 확장하여 이용하는 것이다. 본 논문에서는 망 관리 시스템의 개발과 운용을 돕는 테스트베드를 지원하기 위한 GDMO 문법의 확장 방안과 이를 위한 확장된 GDMO 컴파일러를 소개한다.

GDMO Agent platform based on TMN modeling operating status of network elements and resources to Managed Object as GDMO standard and controled by telecommunication management function requests of manager supporting status of resources. To supporting basic function of these GDMO agent, 13 kinds of system management function has to be implemented. Event-Report-Management function related to all system management functions. The reason that rapidly reporting has been performed as status of resources to manager by continuously communication with real resources. In this paper, a number of approach has been analyzed to communication with real resources for effective event-report management function and we proposed new real resource monitoring schemes of RRMC(Real Resource Message Coordinator) architecture for improving these resulted problem.

Systematic telecommunication network management is essential for operating large-scale integrated networks which consist of various network components manufactured by different vendors. ISO and ITU-T recommend the CMIP-based TMN architecture for this purpose. TMN uses GDMO for the definition of managed objects, and various GDMO compilers have been developed. However, the development of management objects by using these compilers is still a difficult task. In this paper, we present a GUI-based managed objects development environment, MODE. MODE divides managed object codes by system independent code(SIC) and system dependent cede(SDC). By providing development environments for SIC and SDC, MODE can ease the development of managed objects. To show the efficiency of MODE, we develop the managed objects of an ATM switch in MODE.
