QoS-aware middleware for ubiquitous and heterogeneous environments
2001
IEEE Communications Magazine
Preserved Fulltext
This article presents four key aspects of a QoS-aware middleware system: QoS specification to allow description of application behavior and QoS parameters; QoS translation and compilation to translate ...
Middleware systems have emerged in recent years to support applications in heterogeneous and ubiquitous computing environments. ...
For example, solutions have been proposed for setting up and enforcing QoS in IP or asynchronous transfer mode (ATM) networks, in operating system (OS) kernels, and in applications themselves. ...

Recently, there has been a growing interest in self-adaptive systems. Roadmap papers in this area point to feedback loops as a promising way of operationalizing adaptivity in such systems. ...
In this paper, we define a new type of requirement -called Awareness Requirement -that can refer to other requirements and their success/failures. ...
It defines a language to specify goals and can be used to compile monitors from the goal specification and evaluate goal fulfillment at runtime. ...

Sensors monitor runtime application and system performance, and fuzzy logic decision procedures are used to verify whether the contract commitments are upheld. ...
In this model, we introduce the notion of application intrinsic behavior to separate the performance effects of the runtime system from the behavior inherent in the application itself. ...
