Understanding the advantage of business-driven QoS provisioning on the performance of networks

Converged networks carry different types of media using one transmission medium. Fair and target-oriented sharing of a medium´s limited resources among applications using a converged network is still a challenge. Quality-of-Service (QoS) architectures try to overcome this problem by classifying applications and permitting differentiated amounts of available resources to each of them. Our novel approach presented in former work considers the dynamics of applications based on business processes. Instead of working edge-based, this approach works host-based because the identification of applications is more precise on hosts. In this paper, we present the results of a performance analysis. Thereby, the advantage of the business-driven approach on the performance of networks is shown. Instead of just simulating the behavior of our approach, a real testbed is used in which several measurements considering the occurrence of cross-traffic are performed. It is shown that our approach performs well in realistic network environments and does not affect the network in a negative way, but improves the performance according to business processes.
