다양화 및 이질화되어 가는 통신망을 효과적이고 통합적으로 관리하기 위해 TMN(Telecommunication Management Network)개념이 등장하게 되었고, 관리 대상이 실자원이나 시스템, 소프트웨어 등에 국한되지 않고 서비스 영역으로 확대됨에 따라 이 서비스 영역의 관리가 필요하게 되었다. 또한 ATM 망은 구성이 복잡하고 기존 망에 비해 서비스가 확대되었으며, 고속 정보처리로 인한 망 관리 시간의 제한, 다양한 트래픽으로 인한 QoS 관리의 어려움 등의 문제가 대두되었다. 따라서 본 논문에서는 ATM 망의 성능과 QoS 관리를 위한 정보 모델을 설계하였고, ATM 망 성능 및 QoS 관리 에이전트 시스템을 TMN LLA 개념에 따라 설계하였으며, 패트리네트 모델링과 도달성 트리를 이용하여 시스템 모듈의 설계를 검증하였다.

통신망에 대한 고객의 요구는 음성이 대부분을 차지하고 기간통신망은 독점을 유지하였으나, 통신 모드(비음성, 데이터, 화상 등)에 대한 고객의 요구가 다양해지고 통신망은 개방과 경쟁이라는 새로운 위치에 놓이게 되었다. 따라서 이러한 변화에 대처하기 위하여 전세계적으로 차세대 통신망 및 서비스를 제공하기 위한 연구가 활발히 수행되어지고 있다. 이 가운데 가장 중요한 개념은 망요소(network element)를 기능화하고 서비스 빌딩블럭(generic service independent building block)의 집합에 의하여 다양한 미래 통신 서비스에 대한 유연하고(flexible), 일관성(uniform)있는 서비스 제공을 목표로 하는 지능망 구조(Intelligent Network Architecture)와 미래 통신망 및 서비스를 운용, 조절, 유지보수에 필요한 일련의 지원시스팀(support systems) 이상의 관리기능 영역을 제공하기 위한 ITU-T의 TMN(Telecommunication Management Network)이다. 본 연구는, 이 두 개념의 기본적 생각의 간결한 설명 후에, IN과 TMN의 공통점을 분석하고 일반적 통신망 환경에서 미래정보 네트워킹 구조를 위한 기초로써 제공되는 통합 망 및 서비스 관리에 대하여 가능한 통합분야를 명시할 것이다. 즉 지능망의 개념모형(INCM : In Conceptual Model)을 이용하여 TMN과의 상호 연계방안, 지능망 능력 증대 방안 그리고 ETSI 표준화 내용을 살펴봄으로써 향후 지능망 사업 및 통신망 관리 운용 시스팀 구축을 통한 차세대 전기통신망 및 서비스 플랫포옴 구축방안 연구에 도움을 주는 것을 목표로 하였다.

It was required Integrated Network Management Architecture(INMA) with consistency and standardization in order to support efficiently communication service for operators and users. In such ITU-T(International Telecommunication Union - Telecommunication) recommended TMN(Telecommunication Management Network) which is Network management architecture for telecommunication, and intended to achieve uniform and comprehensive network management using standardized network management interface. This paper proposes C31 management services and management functions based on ITU-T and RACE project. This designs C31 INMA based on TMN concept in order to manage efficiently C31 communication network. The C31 INMA supports to manage C31 LAN and WAN devices and lines with global and correspondence, and helps Integrated Network Management system design and implementation.

Local Number Portability (LNP), an Intelligent Network (IN) service, provides the ability to retain existing telephone numbers when switching from one telecommunications carrier to another, from one region to another, or from one service to another. Local Number Portability (LNP), an Intelligent Network (IN) service, provides the ability to retain existing telephone numbers when switching from one telecommunications carrier to another, from one region to another, or from one service to another. LNP is a key service for increasing competition in the local telephone marketplace. Many countries are now establishing detailed rules for ensuring competition between network operators. Because many major carriers will deploy their own LNP databases, a single access point must be provided to effectively manage and distribute updates to the common regional LNP database. This is called Number Portability Administration Center (NPAC). Recently, CORBA is being accepted as one of the key technologies for developing distributed application systems. To use CORBA for managing IN services, several standard organizations are working towards the integration of IN, TMN and CORBA. In this paper, we present our work on applying the TMN and CORBA technology for the service management of LNP. We first propose a CORBA-based LNP service management system architecture, We then present the design and implementation of a LNP service management system using CORBA.

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.

Hwangryunagyo-tang (HT) is a herbal cocktail to treat insomnia induced by yin deficiency with effulgent fire. In the present study, the onset time and the duration time of sleep were measured 30 minutes after thiopental sodium injection. And c-fos immunohistochemistry was performed to find the activated nerve cells of the ventrolateral preoptic nucleus (VLPO) and tuberomammillary nucleus (TMN) sites in the brain. HT significantly increased the number of activated nerve cells in the sleep-inducing center (VLPO), whereas HT significantly decreased the number of activated nerve cells in the arousal center (TMN). It could be concluded that the HT shortened the onset time and increased the duration time for sleep induced by thiopental sodium. And it was confirmed that the mechanism acted by activating the sleep-inducing center (VLPO) and suppressing the arousal center (TMN) in the brain. The results are considered to be useful as scientific evidence HT can be used clinically for the treatment of insomnia caused by yin deficiency with effulgent fire.

To compress the moving picture data effectively, it is needed to reduce spatial and temporal redundancy of input image data. While motion estimation! compensation methods is effectively able to reduce temporal redundancy but it is increased computation complexity because of the prediction between frames. So, the study of algorithm for computation reduction and real time processing is needed. This paper is presenting quantizer effectively able to quantize DCT coefficient considering the human visual sensitivity. As quantizer that proposed DCT-based H.263 could make transmit more frame than TMN5 at a same transfer speed, and it could decrease the frame drop effect. And the luminance signal appeared the difference of $-0.3{\sim}+0.65dB$ in the average PSNR for the estimation of objective image quality and the chrominance signal appeared the improvement in about 1.73dB in comparision with TMN5. The proposed method reduces $30{\sim}31%$ compared with NTSS and $20{\sim}21%$ compared to 4SS in comparition of calculation quantity.

In order to guarantee the user-requested quality-of-service(QoS) and keep the network utilization at maximum it is required to manage the network performance continuously after the network installation. The performance management function should provide the useful information for the network expansion and the capacity reallocation in the future. Currently the TINA provides the specification of the management function of configuration management connection management and fault management ; but the management function of performance management and security management are not well-defined yet. In this paper we propose a TINA-based performance management architecture for the efficient performance management of the heterogeneous networks or NEs with TMN and SNMP management functions. And we examine the proposed architecture into the ATM network (with SNMP and TMN) monitoring. The proposed architecture is based on the distributed processing architecture and the concept the TMN perfo mance management. The proposed architecture have been designed and implemented in multiprocess and multithread structure.

This paper discusses some problems of the TMN-based architecture of integrated network management systems and presents a CORBA-based architecture of distributed network management system with reliability, which maintains location transparency of distributed managed objects and provides an interoperability among heterogeneous networks and systems. In this paper, the proposed distributed management system model has been applied to the TMN based management systems and then considered for qualitative evaluation of system performance. Two different types of implementation models have been proposed: one is a system using a CORBA gateway and the other is a pure CORBA system, which maps all managed objects into CORBA objects. The characteristics of two system model have been compared in the respect of system implementation
