Abstract:
This paper describes an architecture that provides
support for quality of service (QoS) specification and
enforcement in heterogeneous distributed computing
systems. The Quartz QoS architecture has been designed
to overcome various limitations of previous QoS
architectures that have constrained their use in
heterogeneous systems. These limitations include
dependencies on specific platforms and the fact that their
functionality is often limited by design to one particular
area of application. Quartz is able to accommodate
differences among diverse computing platforms and areas
of application by adopting a flexible and extensible
platform-independent design, which allows its internal
components to be rearranged dynamically in order to
adapt the architecture to the surrounding environment.
Further significant problems found in other QoS
architectures, such as the lack of flexibility and
expressiveness in the specification of QoS requirements
and limited support for resource adaptation, are also
addressed by Quartz. This paper describes the
motivations for and design of Quartz in detail, presents a
prototype implementation of Quartz and an analysis of its
design based on experience with a number of applications
that use this prototype.
