The spotlight is thrown on the ubiquitous technology these days, and diverse management technologies are proposed to efficiently manage the networks in the ubiquitous environment. Because each network has its unique management technology, the integrated management of complex networks is a very difficult challenge. In this paper, an integrated network management methodology is proposed to ensure the efficient management of different networks using ontology. Although the proposed integrated network management methodology is quite simple, the definition of this methodology is essential for the integrated network management. Using the $Prot\acute{e}g\acute{e}$ to Ontology development, the terms for the integrated network management were defined, along with the OWL and relevant rules, and several methods were implemented according to the proposed methodology. The process in this paper is considered essential for the network expansion and multiple network management.

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.

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.

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).

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.

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.

인터넷 서비스 가입자망은 다양한 멀티미디어 서비스를 제공하는 새로운 대안으로 제시되고 있는 망이지만 접속 방식에 따라서 여러 가지 형태와 특성을 가지고 있다. 접속 방식 별로 여러 가지의 이기종(異機種) 장비들이 배치되고 있으며, 전국적으로 분산된 가입자 망 장비 및 자원에 대한 효율적이며 집중적인 통합 관리를 위해서는 관리되는 장비의 종류에 무관한 일반적인 정보 모델인 단일화된 개념적/추상적 관리객체 모델이 요구된다. 본 논문은 인터넷 서비스 가입자망을 통합 관리하기 위한 추상적이며 논리적인 관리객체 모델을 제시하였다. 그리고 이를 기반으로 UML을 이용한 객체지향 방법론을 적용하여 가입자망인 DOCSIS 기반의 케이블데이터 서비스를 위한 가입자망과 VDSL서비스를 위한 가입자망에 대해 동일한 모델을 적용하여 하나의 통합된 가입자망을 관리할 수 있는 시스템을 설계하고 구현하였다.

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. Improtance of performance management is growing as many function 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 detemine the magnitude and direction of parameter adjustment. This paper is the second 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 decision making which utilizes the principles of stochastic optimization and learning automata. The developed algorithm can adjuxt four timer settings of a token bus protocol based on the result of performance evaluation. The overall performance management has been evaluated for its efficacy on a network testbed.

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.
