针对现有服务工作流性能评价模型的兼容性和可扩展性问题,设计并实现一种面向用户需求并支持QoS调度的服务工作流性能评价系统SWES(Service workflow evaluation system)。该系统采用组件技术及面向对象编程方法设计,各个组成部分通过标准的SOAP协议通信,使得各模块的组织及建立能独立实现,同时连接网络中UDDI对服务资源进行整合,使系统具有较强的可扩展能力。该系统既提供了用户个性化定制的功能,又能对传统调度算法的QoS指标及扩展QoS指标进行性能评测。实验结果表明,该系统具有较强的兼容性和可用性。
Aiming at the compatibility and scalability of the existing service workflow performance evaluation model, a Service Workflow Performance Evaluation System (SWES) is designed and implemented to meet the needs of users and support QoS scheduling. The system uses component technology and object-oriented programming method design, the various components communicate through the standard SOAP protocol, making the organization and establishment of each module can be achieved independently, at the same time connecting UDDI network to integrate service resources, the system has a strong Scalability. The system not only provides the user customized functions, but also performs the performance evaluation on the QoS indexes and extended QoS indexes of the traditional scheduling algorithms. The experimental results show that the system has strong compatibility and usability.
