Signalling in a component based world

To provide ubiquitous access to applications, the QoS and computing requirements of the various components of the application must adapt.,The authors argue that the appropriate techniques for providing adaptive interfaces is through open implementation, in which the abstractions to control behaviour are couched in the language of the component, not some generic QoS definition language. They describe how open implementation techniques can be applied to determining QoS configuration, and report on their experiences in implementing such an architecture for low bandwidth access to networked multimedia
