Abstract:It is becoming increasingly commonplace for multiple
applications with different quality of service (QoS)
requirements to share the resources of a distributed
system. Within this environment, the resource
management algorithms must take into account the QoS
desired by applications and the ability of the
system resources to provide it. We present a
taxonomy for specifying QoS for the different
components of a distributed system, from the
applications down to the resources. We specify QoS
as a combination of metrics and policies. QoS
metrics are used to specify performance parameters,
security requirements and the relative importance of
the work in the system. We define three types of QoS
performance parameters: timeliness, precision, and
accuracy. QoS policies capture application-specific
policies that govern how an application is treated
by the resource manager. Examples of such policies
are management policies and the levels of
service. We explore each of these components of the
QoS taxonomy in detail
