In this paper, we develop the next generation mobile system based on SBC(Server Based Computing). SBC is one of the popular topic and only one server system is used as multiple personal systems with a terminal, a monitor and a keyboard. The advantages of this system are easy-upgrade, low costs and convenience for each user. But it is difficult to design and manufacture the multimedia streaming system and devices control system for external devices. In this paper, we represent and develops the Mobile system based on SBC and the test performances shows that our system has good performances of multimedia system and security for internet.

In order to solve the problems of maintenance and security for information-infrastructure, public organizations and some of leading companies adopted Server Based Computing(SBC) infrastructure. The effectiveness and possibility of SBC has become focused with the Cloud-Computing infrastructure, which is a extended concept of SBC, as it is being magnified as a main part among the internet business models for the next generation. The purpose of this study was to analyze its probability in elementary and secondary school and find out its effectiveness. In order to do this, three model schools have been selected from GyeongBuk, ChungNam, ChungBuk province and they were managed by SBC infrastructure. And We conducted analysis of satisfaction for teachers and students, interview with teachers and classroom observation as a effectiveness verification. As the results of the analysis, First, we can find out which part we should consider more when we are to adopt SBC infrastructure. Second, the level of satisfaction for teachers is 3.45 and students is 3.2. Therefore, this study was concluded to contribute to find directions what should be considered when setting the SBC infrastructure in elementary and secondary schools.

본 논문에서 우리는 SBC(Server Based Computing)를 위한 씬 클라이언트 개발에 관한 우리의 최근 연구에 대하여 소개한다. SBC 란 현대 사회에서 빠르게 변화되는 소프트웨어(SW)/하드웨어(HW) 기술에 대하여 유지 보수 및 업그레이드 비용에 대한 절감과 인력자원 절감 효과, 보안 환경의 강화, 접근 권한에 따르는 차별성, 안정성 확보 그리고 장비의 간소화를 통한 작업 공간 효율성에 이르기까지, 다양한 장점을 가지고 있는 신개념의 컴퓨터 아키텍처이다. 이를 기반으로 하는 씬 클라이언트는 HDD 및 어떠한 어플리케이션도 설치 할 필요가 없다. 따라서 씬 클라이언트는 고사양일 필요가 없으며 보안, 업그레이드 그리고 데이터 백업에 대한 부담도 줄어든다.

In this paper, we design thin-client framework capable of application sharing & data access on the Internet, and apply related skills, such as X windows system, pseudo server, CODA file system, MPI(Message Passing Interface). We suggest a framework for the thin client to access data produced by working on a server optimally as well as to run server side application, even in the case of network down. Additionally, it needed to reflect all local computing changes to remote server when network is restored. To design thin client framework with these characteristics, in this paper, we apply distributed pseudo server and CODA file system to our framework, also utilize MPI for the purpose of more efficient computing & management. It allows for implementation of network independent computing environment of thin client, also provide scalable application service to numerous user through the elimination of bottleneck on caused by server overload. In this paper, we discuss the implementing method of thin client framework in detail.

최근 각광 받고 있는 서버 기반 컴퓨팅(SBC, Server-based Computing)은 많은 수의 서버가 필요하기 때문에 많은 수의 서버를 관리할 수 있는 관리자 시스템의 필요성이 대두되고 있다. 이에 관리자 네트워크를 필요에 따라, 코맨드 센터(CC, Command Center), 서버 에이전트(SA, Server Agent), 관리자 인터페이스(Manager Interface), 유저 에이전트(UA, User Agent)등 네 가지 모듈로 분리하여 필요한 시스템 기능을 구현하는 것만으로 저비용으로 신뢰성 있는 네트워크를 구축할 수 있는 네트워크 프레임워크를 개발하고, 그 성능을 측정하였다.
