A Web Services Framework Supporting Quality of Services for SOA-based Applications
Paper i proceeding, 2006
Web Services and Service-Oriented Architecture (SOA) has been playing an important role as a middleware for interoperable transactions such as Business-to-Business and Enterprise Application Integration. Popular Web Services frameworks, such as Apache Axis, did not consider the Quality of Service (QoS), though these aspects are high demands in practice. In this paper, we present a framework supporting QoS built on the top of Axis. The framework is transparent with developers on both client and server side, and supports QoS including performance, accessibility, reliability, and security for SOA-based transactions. The design and implementation of our framework provide an easily integrated and flexibly extended approach to SOA-based applications. The key features and implementation methodology are described, with scenarios provided as usage examples of the framework.
