Abstract

It is common among users to have multiple computing devices as well as to access their files or do work at different locations. To achieve file consistency as well as mobility in this scenario, an efficient approach for workspace synchronization should be used. However, file synchronization alone cannot guarantee the mobility of work environment which allows activities to be resumed at any place and time. This paper proposes a ubiquitous synchronization approach which provides cloud-based access to a user's workspace. Efficient synchronization is achieved by combining session monitoring with file system management. Experimental results show that the proposed mechanism outperforms Cloud Master-replica Synchronization in terms of number of I/O operations, CPU utilization, as well as the average and maximum latencies in responding to client requests.

현재 서로 다른 지역에서 여러 대의 컴퓨터 장비를 가지고 파일을 접근하고 작업을 하는 것은 흔히 볼 수 있는 현상이다. 이러한 환경에서 파일의 일치성과 이동성을 이루기 위해서는 워크스페이스 동기화를 위한 효율적인 방법이 사용되어야 한다. 그러나 파일동기화 만으로는 시간과 장소에 관계없이 작업을 재개하는 작업환경의 이동성을 보장하지는 못한다. 본 논문에서는 클라우드를 기반으로 한 사용자 워크스페이스의 접근 방안을 제공하는 유비쿼터스 동기화 기법을 제안한다. 세션 모니터링과 파일 시스템관리 방법을 결합하여 효율적인 동기화 방법을 제시하였다. 실험결과 고객요구에 대한 평균/최대 지연시간 뿐만 아니라 I/O연산의 수, CPU이용율 관점에서 우리의 연구가 Cloud Master-replica 동기화 기법보다 성능이 우수함을 보였다.
