Abstract—As an effective technique for QoS provision, reservation service has been widely applied in various grids. However, plenty of studies have shown that reservation service will bring about many negative effects on system performance, i.e. higher rejection rate and lower resource utilization. To mitigate these negative effects, a relaxed reservation policy is proposed in this paper. It allows grids accepting reservation requests that overlapping with existing ones in two dimensions (temporal and space). In addition, the proposed policy is completely compatible with conventional reservation service, which means it can be applied in all kinds of practical grids. Extensive experiments have been conducted by using real workloads, and the experimental results show that the relaxed reservation policy can achieve higher resource utilization and lower rejection rate comparing to other policies. Also, It shows better adaptiveness when grids are in presence of higher reservation rate.
