In this paper we describe an architecture providing an high speed access control service for ATM networks. This architecture is based on two main components. The first one is a signalling analyser which takes the signalling information as an input and produces dynamically the configuration for our second module. This second module called IFT (Internet Fast Translator) is used to analyse the information located in the ATM cells and currently operates at 622Mb/s. The complete architecture provides the access control at the ATM, IP and transport levels without packet reassembling.
