User-domain multiservice architecture for wired and wireless IP networks

In the context of wired and wireless IP networks, this paper illustrates a user-domain multiservice architecture and proposes layered schemes for its provision of quality of service. Based on the proposed multiservice architecture, a testbed is constructed and implemented. Issues of user-domain multiservice support, such as integrated service, differentiated service, real-time service, data-compression service, wireless-awareness service, and network-awareness service, are addressed and investigated experimentally. The paper describes several case studies conducted in the testbed such as RSVP efficiency, end-to-end combination of differentiated and integrated services, video-on-demand deploying wireless-awareness services, and proactive and reactive applications using network awareness service.
