In this paper we propose an integrated platform to power the symbiosis between networks and services whilst supporting mobility of users. This platform is based on methods for authentication, authorization and payment of services in a roaming environment. Existing technologies are combined and enhanced to provide a blueprint for a platform to leverage the interaction of services with the underlying network. Traditionally, such functions as discovery, authentication and authorization exist in parallel for networks and for services, without any association between the systems. This rigid layered approach is abandoned in favour of one that is more integrated and allows these functions to be reused rather than duplicated. Payment is treated as an essential and inherent part of the architecture, in order to facilitate its commercialization and adoption.

Abstract. Widespread deployment of Hybrid Fiber Coaxial (HFC) systems created a new residential access platform upgrading traditional cable TV networks. which were limited to distributed services. This evolution is driven by demand for faster Internet access from customers frustrated by slow telephone line and ISDN modem speeds. As residential traffic with voice and video-intensive content proliferates. the cumnt generation of cable modems, which are oriented towards best-effort traffic, will need to be enhanced with new capabilities to handle the increased bandwidth and quality requirements. To integrate telecom services presenting diverse quality requirements over the same HFC access infrastructure necessitates a degree of isolation of traffic classes. The difficulty of handling finer aggregations because of the limited MAC reservation resources and the cost limitation of residential access make the scalability of the differentiated services architecture as relevant in the HFC access network as in any traffic multiplexer. An implementation integrating IP and ATM and aligning the system to the DiffServ philosophy is presented in this paper. It constitutes an affordable system solution for residential customers enabling the support of QoS-demanding services.

Abstrocl-The commercial operation of future "4G" mobile wireless nehvork comprising uniformly both IP-based voice and data is widely considered as the next challenge for service providers. Within such an IP-environment with its implicit integration ofthe control and data plane, passive measuring and metering will be one of the key elements for AAA and QoS provision, for performance and fault management purposes. Within the IETF, a real-time flow measurement framework has been developed for measurement and accounting for the fixed Internet infrastructure. This article, aner introducing briefly the IETF "Real-Time Flow Measurement" architecture, a pure IP 4C-architecture together with its key signalling scenarios. and JavslJZEE and Web middleware technology, describes "FlowVis" B high scalable and distributed IP based protocol visualization and verification framework for both signalling and data traffic. Combining the near-real-time capabilities of the existing IETF RTFM with current middleware technology, this framework, "FlowVis" can serve as a starling point for distributed protocol analysis in future 4G nehvorks.
