Integrated management model (SNMP/SMI) for lubiquitous egacy remote communication network or service make possible combination of various architecture. However, legacy management system cannot be applied some problems such as inefficient, complexly, implement and large network by reason of integration of voice and data, wired and wireless, and service area between service provider. For improve this, supplied JMX(Java Management eXtensions) on network management technology from SUN. JMX is integrated architecture for existing network management and monitoring. In this paper, we design and implement for integrated network management through multi-protocol agent using JMX.

By managing various communication networks collectively, Telecommunication Management Network (TMN) has appeared as a concept to aim for the unified and effective communication network operation and maintenance. IMT-2000 and other network such as PSTN, cellular networks and packet witching network that are integrated with IMT-2000 have been developed in different platforms - hardware and operating system, and a same circumstance will happen in the maintenance in the future. Also, it is difficult to approach to the standard for Ｑ3 interface implementation of the agent in TMN system that may occur in the development or the maintenance for the different platform of IMT-2000 and other networks that are integrated with IMT-2000. In order to solve this kind of Problems, this Paper suggests integrated network management agent of IMT-2000 based on the NTS model and Advanced Intelligent Network(AIN).

This study analyzed the offshore plant industry and related regulations such as ISO, IEC, and Norsok Standards to develop an integrated network management system (INMS) capable of both on-site and remote management and configuration of IP-based network equipment in offshore plants. The INMS was designed based on actual specifications and POS plans, and a plan of management was verified through an offshore plant engineering company. Various modules such as PAGA interface modules, CCTV, IP-PBX, and HF-radio communication modules were developed for system implementation. Protocol and data design and screen design were followed by framework development and introduction of the automatic satellite communication function.

본 논문에서는 인터넷 망을 위한 SNMP(Simple Network Management Protocol)를 이용하는 망 관리 시스템과 OSI 망을 위한 CMIP (Common Management Information Protocol)을 사용하는 망 관리 시스템을 상호 연동할 수 있는 통합 망 관리 에이전트 (agent)를 설계, 구현하였다. 서로 다른 두 망 관리 시스템을 통합하기 위하여 본 연구에 앞서 수행한 MOVI(Managed Object View Interface) 개념을 이용하였다. 통합 망 관리 에이전트 설계를 위한 3가지 모델을 검토하고 이 모델들의 장단점을 비교하여 적합한 모델을 선택 하였다. 선택한 모델을 구체화할 수 있는 통합 망 관리 에이전트의 논리적 구조와 구체적인 구현방법 그리고 각 모듈별 작동에 대하여 언급하였다. 본 연구에서는 기존의 망 관리 시스템인 osimis와 ucd-snmp 시스템을 참조 모델로 이용하였다. 본 연구를 통하여 인터넷 망과 OSI 망을 망 관리적 측면에서 연동할 수 있을 뿐 아니라 앞으로 MOVI 개념에서 언급하고 있는 것과 같이 새롭게 정의될 수 있는 망 관리 시스템과의 연동에 대한 확장도 가능하다는 장점을 가진다.

Many new office buildings are being built as intelligent buildings equipped with building automation(HA) systems, office automation(OA) systems, and telecommunication(TC) systems in order to provide pleasant building environment and the ease of maintenance and facility management. Building control systems which are employed in intelligent buildings require varieties of advanced control systems and network systems for efficient integrated management. Design and installation of these types of advanced building control systems take a lot of efforts and also they are costly. In order to design these systems, it is necessary for the designers to have the integrated simulator including proper network system simulation. In this paper, the integrated simulator that consist of HVAC system, lighting system, elevator system, parking system based on the network system is presented. For the development of integrated simulator, AHENA which is the general-purpose software tool for a simulation with reinforced GUI is used.

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.

This paper studied the safety management network system of infrastructure which constructed smart sensors, closed-circuit television(CCTV) and monitoring system. This safety management of infrastructure applied to bridge, cut slop and tunnel, embankment etc. The system applied to technologies of standardization guidelines, data acquirement technologies, data analysis and judgment technologies, system integration setup technology, and IT technologies. It was constructed safety management network system of various infrastructure to improve efficient management and operation for many infrastructure. Integrated safety management network system of infrastructure consisted of the real-time structural health monitoring system of each infrastructure, integrated control center, measured data transmission using i of tet web-based, collecting data using sf ver, early alarm system which the dangerous event of infrastructure occurred. Integrated control center consisted of conference room, control room to manage and analysis the data, server room to present the measured data and to collect the raw data. Early alarm system proposed realization of warning and response within 5 minute or less through development of sensor-based progress report and propagation automation system using the media such as MMS, VMS, EMS, FMS, SMS and web services of report and propagation. Based on this, the most effective u-Infrastructure Safety Management System is expected to be stably established at a less cost, thus making people's life more comfortable. Information obtained from such systems could be useful for maintenance or structural safety evaluation of existing structures, rapid evaluation of conditions of damaged structures after an earthquake, estimation of residual life of structures, repair and retrofitting of structures, maintenance, management or rehabilitation of historical structures.

인터넷 사용 증가로 인한 통신망에 대한 위협은 갈수록 증대되고 있다. 이에 대한 방안으로 많은 보안장비들이 개발되어 설치되고 있으며, 침입차단시스템에 이어 근래에는 침입탐지시스템에 대한 연구와 개발이 활성화되고 있다. 그러나, 네트워크의 규모가 커지고, 관리 대상 시스템의 수가 방대해짐에 따라 현재의 단일 네트워크 단위의 관리로는 해결이 어렵다. 본 논문에서는 IETF에서 진행되고 있는 PBNM(Policy-Based Network Management) 기술을 도입하여 대규모의 네트워크의 보안을 관리하기 위한 통합 침입탐지시스템(Integrated Intrusion Detection System:IIDS)을 설계한다. 통합 침입탐지시스템은 다수의 침입탐지 에이전트로 구성되어 있으며, 시스템의 요구사항과 기능별 요소들에 대하여 기술하고 있다.

Performance management of computer networks is intended to improve a given network performance in order for more efficient information exchange between subsystems of an integrated large-scale system. Importance of perfomance management is growing as many functions of the large- scale system depend on the quality of communication services provided by the network. The role of performance management is to manipulate the adjustable protocol parameters on line so that the network can adapt itself to a dynamic environment. This can be divided into two subtasks : performance evaluation to find how changes in protocol parameters affect the network performance and decision making to determine the magnitude and direction of parameter adjustment. This paper is the first part of the two papers focusing on conceptual design, development, and evaluation of performance management for token bus networks. This paper specifically deals with the task of performance evaluation which utilizes the principle of perturbation analysis of discrete event dynamic systems. The developed algorithm can estimate the network performance under a perturbed protocol parameter setting from observations of the network operations under a nominal parameter setting.
