-This paper describes the ideas behind a new way of running Internet applications on an ATM network. ATM already contains some functionality of the network layer and therefore there is no need to duplicate them in the IP stack, Instead of adapting the TCP/IP stack to ATM at the bottom, we replace the TCP/IP stack with something else that is capable of supporting the QoS needs of applications. The intention is to have Internet applications working over ATM with the same performance as a native ATM application could obtain.
