QoS for Service-Oriented Middleware

Document Type

Publication Date



We propose a Service-oriented Middleware (SoM) that provides an upper level of middleware over rapidly emerging Web Services-based middleware to make it easier to develop complex multi-organizational business applications. Our approach primarily builds upon our experience in building distributed workflow management for multi-organizational processes. Effective and efficient Quality of Service (QoS) management is a critical component of SoM allowing it to guarantee the satisfaction and fulfillment of user and application requirements. This paper reviews a QoS model that also supports ability to automatically compute QoS based on QoS specification of component web Services.
