The Multiple Access (MA) QoS-IP architecture has been designed to provide a generalized, modular and feasible network solution for the DiffServ IP backbones managing enhanced services, originated by access networks with different technologies. This activity was successfully carried out within the context of the Italian MIUR ARCHIMEDE project, aimed at demonstrating a performant technological platform for accessing multimedia information on the cultural heritage by means of an advanced and interactive MPEG-4 multimedia system. Keywords – Internet QoS, MPEG-4, e-services 1. INTRODUCTION The emerging request for distance learning and/or the tourist promotion services is one of the most convincing flywheels for the implementation of advanced networking services over the Internet. In the context of Quality of Service for IP packet flows (QoS-IP) a long history of standards and tools has been run, both at the Data Plane level (e.g. Traffic Control algorithms) and at the Control Plane level (e.g. signalling and policy protocols). From a network perspective, QoS-IP may be summarized in the dynamism (e.g. the service should last as long as the user needs) and in the tailoring (e.g. the network resources allocated for the service should fulfil exactly the end-user requirements) of the end-to-end network service related to the IP traffic. Though some tools for QoS-IP are available in commercial IP routers, their compliancy to these requirements is still far from being an off-the-shelf availability. The main obstacles for such a full and homogeneous deployment reside in the: ± number of protocols available in the access networks for the signalling of QoS requirements (e.g. RSVP, H.323, SIP, MPEG-4, etc.), which makes hard to guarantee the network scalability and flexibility; ± different technologies available in the backbone networks (e.g. DiffServ, MPLS, IPoATM, etc.), which make hard to guarantee standard procedures for the end-to-end service setup, above all when the service has to be deployed across different administrative domains; ± coexistence in the IP backbones of Control Plane and Management Plane based procedures for traffic engineering (TE), traffic survivability, etc., with further complications deriving from the inter-Autonomous System (AS)/cross-technology operation. The ARCHIMEDE project has been conceived in this
