Introducing ATM in the Internet

This work provides a survey of the main approaches proposed so far by both standardization bodies and manufacturers, for the exploitation of ATM technology into the Internet. The integration level between the ATM and IP protocols is used as the driving thread in the presentation: solutions conforming to the overlay model, which considers ATM as a data-link technology over which IP packets are sent, are considered first. Then, solutions providing various levels and flavors of integration are taken into account. In the characterization of each approach we focus on its ability to provide guaranteed quality of service. Area di interesse: ATM e Internet 1 1. Introduction Internet is growing up: not only is the number of its users increasing daily, but the applications they want to run are also becoming ever more demanding. Multimedia applications require high bandwidth, constant-delay services, whose adequate support is being ensured by increasing the bandwidth of links connecting route..
