Abstract

In this paper we report the development and implementation of Q-Soft, a Quality of Service (QoS) software framework, that provides QoS support for real-time (RT) applications in wired and wireless home networks. RT applications such as voice and video are delay and delay variation sensitive, i.e., in case the packets incur large delays and delay variation, the quality of the application is severely degraded (e.g., the video is choppy and the voice is not clear). Successful launching of RT applications necessitates end-to-end QoS guarantees in terms of bandwidth, bounded delays and delay jitter. Q-Soft is independent of the network interface card and of the multimedia applications we run. The experimental results of our solution were obtained on a PC-Windows-based testbed consisting of a home network (wired or wireless) connected to the Internet via a residential gateway. The experimental results we have obtained provide evidence that our solution provides QoS service support for multimedia applications.
