Adding QoS to web service transaction management

In e-business, we often need to integrate services across distributed, heterogeneous, dynamic virtual organizations. This integration can be technically challenging because of the need to achieve various Qualities of Service (QoS). Achieving a general QoS support for Web service transaction will play an important role for the success of this emerging technology. Unfortunately, current Web service transaction environments do not offer comprehensive QoS support. To enhance with QoS management, we propose a QoS model that allows for the description of Web service transaction components. Then we present a QoS-based commit protocol to enable the QoS integration in Web service transactions.
