Abstract

Web services technology is evolving as a base for implementing service-oriented architectures (SOA), which has become an important architectural style for Web applications development. As Web Services development has grown considerably, the need for Quality of Service (QoS) has become a substantial aspect for developing a reliable service applications. In diverse business domains, Web services need to exhibit quality characteristics such as response time, availability, and reliability. However, a problem arises when a Web service is modified, updated or replaced by a new one. The new Web service may not fully match the QoS features provided from the previous one, this unavoidable problem is recognized as a mismatch. Mismatches are found in different layers of the Web service interoperability stack and corresponding adapters are needed to deal with this issue. This paper proposes a study to investigate the feasibility of achieving interoperability in Web services by evaluating the functionality of adapters when mismatches appear at the policy layer, which includes non-functional properties like QoS.

使用策略调整Web服务

Web服务技术正在发展成为实现面向服务的体系结构(SOA)的基础，SOA已成为Web应用程序开发的重要体系结构风格。随着Web服务开发的显著增长，对服务质量(QoS)的需求已成为开发可靠服务应用程序的一个重要方面。在不同的业务领域中，Web服务需要表现出响应时间、可用性和可靠性等质量特征。但是，当Web服务被修改、更新或替换为新服务时，就会出现问题。新的Web服务可能不能完全匹配前一个Web服务提供的QoS特性，这个不可避免的问题被认为是不匹配。在Web服务互操作性堆栈的不同层中发现不匹配，需要相应的适配器来处理此问题。本文提出了一项研究，通过评估策略层出现不匹配时适配器的功能(包括QoS等非功能属性)来调查在Web服务中实现互操作性的可行性。
