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.
