가용성과 작업의 균등분배를 위한 JMX기반 클러스터 서버시스템

Information demands are fast rising, and today's computer system servers need to serve as many users and as many kinds of applications as possible, Therefore, a clustering system is mainly the internal structure of a server. Technically the server needs to be designed to load balance well. In this paper, a new clustering scheme is suggested for easy construction and maintenance of a server using Java Management Extensions. Recent Java technologies such as J2ME, J2EE, JMX, Jini and JDMK made it possible to integrate existing system functionalities based on the Java technology. Moreover, the adoption of application servers based on EJB technology speeds up rapidly. Recently, the demand of supporting on-line multimedia contents which have multiple terabytes size data increases. To address this problem, a clustering system which interconnects multiple computers with moderate price range seems to be very popular as an alternative to a single, high performance server. Experiments show that our system is easy to construct, expand, and load balance well even for dynamic situations of node additions, deletions, and malfunctions.
