CORBA 기반 SNMP 게이트웨이

정영준,송화선,서희정,김주영 강원대학교 정보통신연구소 1999 정보통신논문지 Vol.3 No.-

As telecommunicaton networks becomes more complex and intelligence, it is essential to develop an integrated network management system between heterogeneous telecommunication networks. To fulfil such demands, one solution is CORBA, which provides a distributed platform, in this paper, we present the design and implementation of a gateway between CORBA and SNMP, called as an Internet management protocol. The proposed scheme allows a CORBA managerto access the SNMP MIB without special transformation of SNMP managed objects and only but using SNMP API which the gateway provides. Also since managed objects are represented in CORBA IDL, a new SMI can be updated only by recompiling the interface. Consequently this gateway approach gives a great of advantages in a point that any changes of managed object implementation on managed agents MIBs are not required.

동적 임계치를 이용한 ATM ABR 트래픽 제어의 성능 및 공정성 분석

정영준,송화선 강원대학교 정보통신연구소 1997 정보통신논문지 Vol.1 No.-

The rate control method for the Available Bit Rate(ABR) service classes has been developed in ATM Forums over Asynchronous Transfer Mode(ATM). This paper proposes a simulation model of ABR traffic controls based upon a highway merge model and dynamic thresholds for congestion control, to find the optimum parameter values and investigate their performance and fairness with the change of QBR traffic control parameters. Also in this paper, an ABR feedback control models such as FECN(Forward Explicit Congestion Notification), BECN(Backward Explicit Congestion Notification), and BP(Backpressure) with RM(Resource Management) based EPRCA has been analyzed and characterized.

CORBA 기반의 분산 통합 망관리 시스템

정영준,김남호,송화선 강원대학교 정보통신연구소 1999 정보통신논문지 Vol.3 No.-

This paper analyzes some problems for the architecture of TMN-based integrated network management systems and presents a CORBA-based integrated network management system, which maintains transparency and scalability of distributed managed objects and reliably provides interoperability between heterogeneous networks and systems. In this paper, the proposed system model has been applied to the TMN based management systems and then analyzed for qualitative evaluation of the system performance. To implement the proposed system, two different types of model have proposed: one is a system using a CORBA gateway and the other is a system, which transforms all managed objects into CORBA objects. The former model is adequate for the implementation of a short-term integrated network management system and the latter one is good for a long-term management system.

The upper stream area of the north Han river, which is located around the Chunchon city of the Kangwon province, is out essential resources, which supply clear drinking water to the capital city of out conutry, Seoul. This area has also produced stone and aggregate resources required for building and road constructions in the capital area For preservation and planned-development of this area, in this study, we have developed an integrated management system for natural resources, based upon geological information technologies. This system includes powerful tools and functions for resource management such as information collection, edition, processing, modeling, analysis, and visualization. As a result, this system may give us capabilities to efficiently handle a variety of resource management issues such as the analysis of underground resources, the planning and development of natural resources, the protection of environment and their related projects.

탄성파를 이용한 CDP 데이터 처리는 지질 분석에 매우 유용한 기법이다. 본 연구에서는 CDP처리 데이터의 품질과 결과를 개서하기 위해 다양한 디지털 신호처리를 이용하여 스펙트럼 분석, 필터링, 디컨벌루션, 구조보정 등의 알고리즘을 설계 구현하여 보았다. 특히 마이크로 컴퓨터에서 설계 구현된 CDP 데이터 처리는 지금까지 값비싸게 생각됐던 탄성과 데이터 처리를 야외에게 할 수 있도록 하였다. 따라서 탐사 자료의 수집 즉시, 그 데이터를 처리할 수가 있어 잘 알지 못하는 지역의 탐사의 시행 착오를 줄이고 매우 유효하게 쓰일 수 있다. The CDP processing of the seismic reflection wavelets is very useful to analyze the geophysical structure of the earth. In this study, we designed and implemented many seismic processing algorithms such are spectrum analysis, filtering, deconvolution, and migration by using the DSP technologies in order to enhance the quality and results of microcomputer allows users to perform the in-field seismic data processing. Thus since the data can immediately be processed in the field when the seismic exploration data can be collected, this study can be useful for geophysical exploration.

신성현,송화선,김진호,정영준 강원대학교 정보통신연구소 2004 정보통신논문지 Vol.8 No.-

As information processing recently increases over Internet. there have been many researches about designing an efficient storage system to process a huge amount of information, which is based upon DTD in XML However, most of them have some difficulties in meaningful and structural presentation of XML documents and some restrictions in integration of many heterogeneous documents. In other word, we need a storage system which well-defines the structure of heterogeneous XML documents and integrates them. In this paper, we proposed a technique of an XML documentation storage system using DTD integration graphs based on CSB+-tree. This technique retrieves structural information from elements of XML documents, creates a CSB+-tree based DTD integrated graphs of the man storage system, and generates an integrated storage system by using element mappings. The proposed technique utilizes the man storage system more efficiently in space and provides more faster response time.
