Abstract:
Quality of service is becoming more and more important in
distributed systems. Current middleware systems lack quality-of-service
support on the application and on the system level. AspectIX is a
CORBA-compliant middleware platform that defines generic interfaces to
control quality-of-service and an infrastructure for quality
implementations. AspectIX is based on a fragmented object model that
can provide transparent client-side quality implementations. Quality
implementations can be weaved into functional fragments using a
hierarchy of Weavelets which are modular code-transforming software
components. A distributed policy decision engine allows administrators
to influence object-internal decisions, e.g., decisions about how to
implement the current quality-of-service requirements.
