Dynamic Subscription-Based QoS Service for Traffic Optimization

Real-time Internet services such as video transmission and online gaming often require privileged treatment in the Internet routers and wireless links in order to meet their real-time QoS requirements. The challenge is to know which are the services requiring higher priority and when this special treatment is needed. In this study, we introduce mechanisms to intelligently classify different traffic flows and to utilize this information in a dynamic adjustment of traffic priorities. In the presented solution, mobile stations can dynamically subscribe to special treatment for their network services. We capitalize on a deployment of the solution in the context of scalable video and employ fixed WiMAX to provide broadband quality of service enabled wireless connection. Beyond introducing and demonstrating the feasibility of such a deployment, our measurement results attest that dynamic traffic priority change can provide sufficient mechanism to sustain the quality of the real-time service despite the unreliable wireless link.
