“…Before presenting and discussing the simulation results, a brief overview on the implementation of the simulation model in comparison to the QoS-driver presented in [1] and [2] is given. The simulation model has been implemented using the simulation framework OMNeT++ [14] and its network simulation package INET.…”

“…Because a semantic behavior in the QoS provisioning process for computer networks is not possible using existing approaches, we developed a novel QoS provisioning scheme [1] briefly described in the following. The approach enables the network to behave context-aware on the basis of predefined business processes (also called business workflow).…”

“…Additionally, it returns a task's priority or the according Differentiated Service Code Point (DSCP) value. Further information about the scheme and its internal behavior can be found in [1] and [2]. The traffic generating system process represented in each task is a reliable information to identify an application.…”

“…Semantic QoS provisioning is a novel approach to overcome problems of existing ones, especially the problem of considering user behavior and the dynamical requirements of applications as well as services over time. This approach has been presented in [1]. In comparison to most of the other schemes, sQoS is a host-based approach that shifts the functions of identification and classification from the edge-routers towards the traffic generating hosts because the identification of traffic generating applications and services, which is impossible if Application Layer contents are encrypted or Transport Layer ports are not used as intended, is more successful on the hosts.…”

“…The results are presented in [2]. In [1] as well as [2], the semantic QoS behavior was validated using the scenario of business processes to analyze the improvements in real world scenarios. The analysis of results received using a prototype may be affected by several constraints and system effects that are not related to the approach itself.…”

Semantic QoS Provisioning (sQoS) is a novel approach to dynamically control the permitted level of QoS per flow. This scheme has been presented in [1] and [2]. Using a prototype, which has been implemented as a QoS-driver for Windows Vista/7, we have shown that our approach does not affect the performance of the hosts. In this paper, we present a simulative performance study of the proposed scheme. On the basis of a new simulation model of the semantic QoS provisioning scheme sQoS, the behavior of the approach is analyzed within several measurements. These focus on the analysis of the automated detection of the execution context and context position as well as the performance of the network traffic. The results show that the sQoS approach performs well in DiffServ environments and increases the overall performance.
