scope:

The present document covers a use case analysis for the interaction of the TISPAN Resource and Admission Control Sub-System (RACS) with the Customer Premises Network (CPN), as well as an analysis of required functional entities, reference points and information flows. Furthermore, requirements for interworking with in-home QoS control mechanisms are studied. The study concludes with a recommendation on the way, or ways, how RACS and CPN should interact and interface, i.e. on one or several interworking architecture(s) proposal(s), taking into account security and privacy aspects.
