Abstract: As content providers turn their attention towards the residential market, offering triple-play services over the expanding broadband access network, it is necessary to guarantee appropriate levels of quality. However, provisioning such services over a heterogeneous network is facilitated by adopting a common |language| of defining quality policies. In this paper, we attempt to provision multimedia-rich services over such a network with guaranteed quality, based on an |overlay| IP-based approach. This |all-IP| approach will allow us to influence the treatment of service traffic along the network path from the content provider|s network up to the home network, regardless of underlying technologies.

Keywords: internet protocol; quality of service; QoS; home networks; multimedia services; heterogeneous networks; overlay model.
