Integration of a QoS aware end user network within the TISPAN NGN solutions
MetadatosMostrar el registro completo del ítem
The development of speciﬁcations for Next Generation Networks has introduced a new network paradigm that has features and capabilities to ensure the provisioning of new value-added multimedia services over the broadband access technologies that are currently being deployed in the market. In this respect, the TISPAN group from ETSI is working in the speciﬁcation of a Next Generation Network, mainly based on IMS as the service signalling architecture. Nevertheless, the ﬁrst release of the TISPAN NGN does not consider the QoS provisioning mechanisms in the end user environment. QoS support will necessarily require to extend the QoS scope to the client premises, in order to provide a real end-to-end QoS. In this scenario, the ﬁgure of a Residential Gateway in the user network plays a crucial role. In this paper, an architecture is presented to allow the automatic conﬁguration of the QoS parameters in a Residential Gateway directly connected to a TISPAN compliant Next Generation Network. This architecture should support the processing of the SIP signalling ﬂows exchanged between the end user environment and the Core IMS in the NGN, deriving relevant information from the SDP payloads and accordingly conﬁguring the QoS parameters in the user network environment.
