Packaging Quality of Service Control Behaviors for Reuse

Two limitations of the current implementations of adaptive QoS behaviors are complexity associated with inserting them into common application contexts and lack of reusability across applications. What is needed is a way of bundling all the specification for systemic behavior into one place, and making it feasible to insert the collection of related QoS management artifacts into applications as a single, reusable behavior. As a means of addressing these issues, we have developed a new abstraction intended specifically to bundle together the lower level abstractions, specifications and implementations associated with providing adaptive QoS behaviors in a manner which is both easier to package and makes the behavior bundle reusable in a variety of applications and styles of use. In this paper we introduce the concept of “qoskets” as reusable systemic behaviors, lay out elements of our design for qoskets within the QuO framework, and use a case study example to highlight the issues of using qoskets in practice.
