Abstract

Monitoring and analysis of QoS are crucial steps for the provisioning of self-healing Web services and for managing web service-based distributed interactive applications. Dealing with these issues becomes even more challenging when applications are dynamically built by composition of distributed services involving different service providers. In this case, assuming access to the internal logic and its implementation within the composed Web services is not realistic. In this paper, we propose an architectural framework for monitoring and analysis of QoS driven by models for QoS analysis. This framework has been implemented and experimented for the web service technology within the European WS-DIAMOND project. We consider the general context where only SOAP messages between web services are monitored. The main novelty of our approach is, on the one hand, to provide a generic application-independent framework. On the other hand, we provide models allowing QoS deficiencies to be detected and considered as an indicator of the health degradation of the monitored Web services.

用于自修复web服务的非侵入性QoS监控和分析

QoS的监视和分析是提供自修复Web服务和管理基于Web服务的分布式交互式应用程序的关键步骤。当应用程序是通过涉及不同服务提供者的分布式服务的组合动态构建时，处理这些问题变得更加具有挑战性。在这种情况下，假设在组合的Web服务中访问内部逻辑和实现是不现实的。在本文中，我们提出了一个由QoS分析模型驱动的QoS监控和分析的体系结构框架。这个框架已经在欧洲WS-DIAMOND项目中为web服务技术实现并进行了试验。我们考虑仅监视web服务之间的SOAP消息的一般上下文。我们的方法的主要新颖之处在于，一方面，提供了一个通用的独立于应用程序的框架。另一方面，我们提供了允许检测QoS缺陷的模型，并将其视为被监视Web服务健康退化的指示器。
