An end-to-end QoS management architecture

The paper describes a distributed quality of service (QoS) management architecture and middleware that accommodates and manages different dimensions and measures of QoS. The middleware supports the specification, maintenance and adaptation of end-to-end QoS (including temporal requirements) provided by the individual components in complex real time application systems. Using QoS negotiation, the middleware determines the quality levels and resource allocations of the application components. A prototype was implemented to demonstrate its practicality. The paper also discusses how protocol parameters are determined in our architecture and what their performance implications are
