Abstract

In this paper, we propose an architecture for Quality of Service (QoS) control with a proxy server for multimedia applications in heterogeneous communication environments of wired and wireless networks. The concept is based on a traffic scheduling mechanism on the application level for supporting various mobile user traffic streams. The proxy server is located in the base station and is responsible for user profile management and QoS adjustment. Via an application user interface, the user can click on a quality button to send an user feedback to express the actual required QoS. The concept is furthermore characterized by the gathering of queue lengths of packet flows and the calculating of the loss probability for QoS monitoring in the proxy server.
