Abstract:

In order to prevent the violation risk existing in the resource reservation,a novel resource reservation strategy based on the quantified balance between benefits and risks is proposed.The strategy takes into consideration the statistical logs of actual reservation services and uses the utility function to change the multi-objective programming problem of the reservation model into a quadratic one.By solving the quadratic programming problem,a suitable reservation scheme can be determined.Moreover,theoretical analysis is performed to prove the validity and to present the solution to the model,and some simulations are carried out to verify the effectiveness of the proposed strategy in a large-scale simulated grid system.Simulation results indicate that the proposed strategy effectively guarantees the quality of service and provides optimal source reservation strategy according to the risk preferences of different grid services.Thus,the conflict between the reservation violation risk and the resource utilization rate is successfully prevented.
