초록

본 논문에서는 분산 객체 관리의 편의성을 제공하고, 고장 발생시에도 안정된 서비스를 가능케 하는 고장포용 객체그룹(Fault-Tolerant Object Group, FTOG) 프레임워크를 제안한다. FTOG 프레임워크는 서비스 우선순위와 체크포인트 방법을 이용하여 두 가지의 고장 회복 방안을 제공하며 퍼지 기반의 부하 추론 과정을 통한 부하 분산을 수행하여 서비스 실행에서의 효율성을 높인다. 또한 가상의 홈네트워크 환경을 구성하고 FTOG 프레임워크를 적용하여 시뮬레이션을 통해 분산되어 있는 객체들의 관리 및 부하 분산 등 본 모델의 안정성 및 신뢰성을 검증하였다.

In this paper, to achieve consistency maintenance as well as stable service execution, we build a Fault-Tolerant Object Group framework that provides both of the group management service and the load scheduling service. The group management service supports the object management such as registration and authentication, and provides two schemes for failure recovery using the service priority and the checkpointing. In the load scheduling servile, we improve the effectiveness of service execution through the reasoning process of object loads based on the ANFIS architecture. The effectiveness in the performance of the developed framework is validated through a virtual home-network simulation based on the FTOG framework.
