受服务质量约束的策略在保证用户所请求的服务质量方面具有优势。即使数据存储库发生良性故障，Quorum系统也可以确保复制数据的一致性和可用性。提出了一种基于Quorum的资源管理方案，资源Quorum包括中间件实体和网络实体，两者都能满足应用的服务质量要求。为了优化资源定额的性能和使用成本，我们还提出了一种启发式配置算法。我们评估了基于医疗保健的心电应用的仿真和实验，因为这种应用需要传输千兆字节的数据和分析复杂的心电信号。仿真结果表明，随着传输的数据量和计算任务的增加，网络能力比计算能力更重要。实验结果表明，与基于策略的管理方案相比，使用启发式算法可以减少心电应用程序的总执行时间。
QoS-constrained policy has an advantage to guarantee QoS requirements requested by users. Quorum systems can ensure the consistency and availability of replicated data despite the benign failure of data repositories. We propose a Quorum based resource management scheme, which resource Quorum includes middleware entity and network entity, both can satisfy requirements of application QoS. We also suggest a heuristic configuration algorithm in order to optimize performance and usage cost of Resource Quorum. We evaluate both simulations and experiments based on the electrocardiogram (ECG) application for health care, because this application requires transferring giga-bytes of data and analyzing complicated signal of ECG. Simulation results show that network capabilities are more important than computing capabilities, as both sizes of transferred data and computation task increases. Experimental results show that our scheme can reduce the total execution time of ECG application by using proposed heuristic algorithm compared to policy based management scheme.
