Abstract:
Grids and Mobile Grids can comprise the basis and the enabling technology for pervasive and utility computing due to their ability of being open, highly heterogeneous and scalable. Nevertheless, the process of selecting the appropriate resources and initiating the execution of a job is not enough for providing quality in a dynamic environment such as a mobile Grid, in which changes are numerous, highly variable and with unpredictable effects. In this paper we present a scheme for advancing and managing Quality of Service (QoS) attributes contained in Service Level Agreement (SLA) contracts of Grids that follow the Open Grid Services Architecture (OGSA). In order to achieve this, the execution environment of the Grid infrastructure establishes and exploits the synergies between the various modules of the architecture that participate in the management of the execution and the enforcement of the SLA contractual terms. The approach that is followed is based on a layered structure of a Grid infrastructure which positions the Grid services middleware in collaboration with both the application services and the network services in order to provide an adjustable quality of the requested services. The components that manage and control the execution in the Grid environment interact with the suit of the SLA related services exchanging information that is used to provide the quality framework of the execution with respect to the agreed contractual terms. The described scheme has been implemented in the framework of the Akogrimo IST project.
