Abstract

This paper addresses the issue involved in dependability of distributed mobile agents in the Internet environment. We propose an architectural framework for the Internet applications making mobile agents into fault-tolerant. The replication of agents and data is of great importance to achieve fault tolerance in distributed systems over the Internet. This research focuses on the replication component for the proposed fault-tolerant mobile agent framework. We present and analyze the performance results obtained when doing simulation study on the effects of the degree of replication, the active and passive replication strategies, and the replication scale.

본 논문에서는 인터넷 환경에서 분산 이동 에이전트의 신뢰성에 관련된 이슈를 논한다. 인터넷 응용을 위해 이동 에이전트들에 고장-감내하도록 만든 구조 프레임워크를 제안한다. 에이전트 데이터를 복제하는 레플리케이션 기법은 인터넷을 통한 분산 시스템에서 고장 감내를 획득하기 위해 매우 중요하다. 본 연구의 초점은 제안된 고장-감내 이동 에이전트 프레임워크에 대한 레플리케이션 컴포넌트 부분이다. 레플리케이션 차수, 능동형과 수동형 레플리케이션 전략, 레플리케이션 규모에 따른 효과에 대해 시뮬레이션 연구를 통해 얻은 성능 분석 결과를 설명한다.
