QoS management is nowadays a mandatory feature in current broadband residential gateways developments. The interconnection between different QoS domains has to be treated into different steps in order to provide a reliable end-to-end QoS solution. The scenario analyzed in this paper is the mapping between QoS requirements in residential users connected to a broadband access network across a multiservice broadband access gateway. Different approaches to provide QoS in the access network are discussed as well as their impact in the design of a residential gateway. An architecture of a gateway based on IMS (IP Multimedia Subsystem) as SIP-based signaling domain for multimedia services is presented with the corresponding adaptation to a broadband fixed access scenario according to Next Generation Networks (NGN) standardization. Finally, the implementation of a prototype of the QoS-enabled gateway, based on the Click! modular router [1], is described to demonstrate end-to-end QoS provisioning for multimedia services. This prototype allows us the demonstration of (1) an innovative way of extending gateway device functionalities using Click! and (2) the feasibility of residential gateway architecture proposed. The work presented in this paper has been developed within the framework of the 6th Framework Programme IST MUSE [2] project.
