이 문서에서는 체크포인트 및 롤백 복구 기능을 갖춘 단순하고 신뢰할 수 없는 파일 시스템에 대한 두 가지 시뮬레이션 모델을 고려합니다. 모델 1에서는 미리 지정된 시간에 체크포인트가 생성되고, 마지막 체크포인트 이후 메인 메모리에 있는 정보가 보조 매체에 백업된다. 반면, 모델 2에서는 처리가 완료된 트랜잭션 수가 미리 정해진 수준에 도달한 시점에 체크포인트가 실행된다. 그러나 거래의 도착 및 처리와 관련된 대기열 효과를 무시할 수 없다면 근사법을 사용하지 않고 이러한 모델을 분석적으로 처리하는 것은 어렵습니다. 우리는 GSPN(generalized stochastic Petri net)을 적용하여 두 가지 체크포인트 체계 하에서 시스템의 확률론적 동작을 나타냅니다. GSPN 시뮬레이션 전반에 걸쳐 고려 중인 체크포인트 모델의 유지 관리 가능성을 정량적으로 평가하고 최적의 체크포인트 정책 및 관련 시스템 가용성에서 모델 매개변수의 의존성을 조사합니다.

Abstract: This paper considers two simulation models for simple unreliable file systems with checkpointing and rollback recovery. In Model 1, the checkpoint is generated at a pre-specified time and the information on the main memory since the last checkpoint is back-uped in a secondary medium. On the other hand, in Model 2, the checkpointing is executed at the time when the number of transactions completed for processing is achieved at a pre-determined level. However, it is difficult to treat such models analytically without employing any approximation method, if queueing effects related with arrival and processing of transactions can not be ignored. We apply the generalized stochastic Petri net (GSPN) to represent the stochastic behaviour of systems under two checkpointing schemes. Throughout GSPN simulation, we evaluate quantitatively the maintainability of checkpoint models under consideration and examine the dependence of model parameters in the optimal checkpoint policies and their associated system availabilities.
