A.: Qos management in fixed broadband residential gateways

Abstract: 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 QoSenabled gateway, based on the Click! modular route
