The execution of business processes is supported by running many applications within a
corporate network. Each business process includes several tasks which have different
priorities expressing each task's relevance in helping to achieve the related business
objectives. The provisioning of a certain level of QoS according to the requirements of an
entire business process can hardly be accomplished using existing QoS provisioning schemes
because these do not account for the dynamic requirements introduced by business processes.
The definition of a certain level of QoS using the existing models is just driven by technical
aspects of the running applications. A novel business process aware semantic QoS
provisioning scheme that accounts for the dynamic requirements and permits applicationindependent
usage is in the focus of my research. In the business world the priority of a task
depends on the current context it is executed in. So equal tasks may need different conditions
of QoS in different situations, which can be characterized by the tasks that ran before or run in
parallel. Therefore, the semantic behavior is based on the entire business processes as input
for the QoS provisioning process. With the proposed QoS provisioning scheme a fair
application conditioning can be achieved that is much closer to the business requirements on
QoS. For the validation of the scheme, it has been implemented as a QoS-driver in different
operating systems and simulated in Omnet++.
