초록

유비쿼터스 컴퓨팅은 네트워크로 상호연결된 프로세서로 구성되며, 하나 이상의 컴퓨터로 이루어진다. 따라서 한 시스템의 단일 컴포넌트 뿐만 아니라 전체 시스템의 가용도를 유지할 수 있어야만 한다. 본 연구에서는 사람의 간섭을 최소화하면서 예기치 못한 결함이 발생하여도 서비스를 지속적으로 제공할 수 있는 능력을 시스템에 부여하기 위한 오토노믹 자가 관리 기법을 제안하고 설계한다. 또한 시스템 로그 분석 결과를 통한 서비스 부하 모델을 근간으로 제안한 메커니즘의 효율성을 검증한다.

A ubiquitous computing system could be constructed not only with one computer but with networks of computers (or ether devices with computing power) embedded in everyday objects. For this, dependability must be guaranteed for each single component of a system and for the whole system which might be more than just a sum of its components. This paper proposes an autonomic self-management mechanism that ran operate for 24 hours/day with the minimum human intervention. In addition, we validate the autonomic fault management scheme based on a workload model derived from the system log analysis.
