Abstract

Currently, many people have been researching diverse mechansmims related to a resource access control in Grid environment. Mostly Grid user's resource access control was designed to authorize according to their attributes and roles. But, to provide Grid with resources continuously, a resource access based on utility computing must be controlled. So, in this paper we propose and implement mechanism that intergrates Grid accounting concept with resource access control. This mechanism calcuates costs of Grid service on the basis of accounting, and determines based on user's fund availibility whether they continue to make use of site resources or not. Grid jobs will be controlled according to a site resource access control policy only if the amount of available fund is less than its costs. If Grid job completed, resource consumer pays for the costs generated by using provider's idle resources. Therefore, this paper provides mechansim to be able to control user's resource access by Grid accounting, so that it is evaluated as the research to realize utility computing environment corresponding to economic principle.

현재 그리드 환경에서 자원 접근 제어에 관련된 다양한 방법들이 연구되고 있다. 대부분 그리드 사용자의 자원 접근 권한은 사용자의 특성 및 역할에 따라 부여하도록 설계되었다. 그러나 그리드에 안정적인 자원을 지속적으로 제공하기 위해서는 유틸리티 컴퓨팅에 의한 자원 접근 제어가 이루어져야 한다. 따라서 본 논문에서는 자원 접근 제어에 그리드 어카운팅 개념을 접목시킨 메커니즘을 제안한다. 이 메커니즘은 자원 사용에 대한 어카운팅 정보를 기초로 처리 비용을 산출하고, 사용자의 가용 자금에 따라 자원 접근 여부를 결정하게 된다. 만약 사용자의 가용 자금이 자원 사용에 대한 처리 비용보다 부족할 경우, 사이트의 자원 접근 제어 정책에 따라 그리드 작업을 제어하게 된다. 최종적으로 그리드 작업이 완료되면, 자원 소비자가 자원 제공자측의 유휴 자원을 사용함으로써 발생되는 처리 비용을 지불한다. 그럼으로 본 논문은 그리드 어카운팅에 의한 사용자의 자원 접근을 제어할 수 있는 메카니즘을 제공함으로써, 경제 원리에 준하는 유틸리티 컴퓨팅 환경을 실현할 수 있는 연구로 평가된다.
