Adaptive Quality of Service Management for Next Generation Residential Gateways
MetadataShow full item record
The TISPAN workgroup inside ETSI is currently working on accommodating the IMS (IP Multimedia Subsystem) architecture, which has been created for the mobile world, to the ﬁxed scenario where there is a new important element to be taken into account: the Residential Gateway (RGW). This element is typically considered as a customer device where providers do not usually have anything to conﬁgure. However, in order to achieve real end-to-end Quality of Service (QoS) this cannot be true anymore. This paper focuses on the way that a RGW is capable of conﬁguring itself (an interface with the providers is also available), regarding Quality of Service parameters, into a Next Generation Network (NGN) scenario. The proposed RGW architecture is also ﬂexible enough so as to adapt the QoS management mechanism to diﬀerent possible scenarios, e.g. conﬁgured by the provider, by the customer or even autoconﬁgured by the RGW itself. A speciﬁc scenario, where a RGW is deployed in the TISPAN NGN architecture, will be explained and validated to proof the concept of the RGW architecture.
