摘　　要：目的研究网格资源QoS指标的测量与监控并实现该系统,为网格资源管理奠定基础。方法分析QoS指标的统一度量方式,采用Java的JNI方法实现与平台无关的资源QoS指标的测量与监控系统。结果应用Java语言编程实现了系统,该系统可以对网格资源QoS指标进行提取并实时监听QoS指标的动态变化。结论该系统可以实时为高QoS需求的用户提供服务,具有良好的动态可扩展性,具有良好的扩展性和移植性。Objective： To study and implement the measure and monitor system of QoS metrics of grid resources to lay a solid foundation for grid resources management. Methods： The uniform measure methods of QoS metrics are analyzed. The platform less measure and monitor system of QoS metrics of grid resources is implemented by using the JNI method of Java, Results： By programming with Java, the presented system is realized, It can extract the QoS metrics of grid resources and monitor the dynamic changes of OoS metrics. Conclusion： This system can provide real time services for users with high QoS requirements and has good dynamic expandability.
