Abstract The Quality Objects (QuO) middleware is a set of extensions to standard distributed object computing middleware that is used to control and adapt quality of service in a number of distributed application environments, from wide-area to embedded distributed applications. This paper compares and contrasts the characteristics of key use cases and the variations in QuO implementations that have emerged to support them. We present these variations in the context of several actual applications being developed using the QuO middleware.
