ATM as a Link in an ST-2 Internet

ATM promises to be a broadband network that provides quality of service guarantees for real time multimedia applications. ST-2 is an experimental connection-oriented protocol that provides guaranteed support for streams across an internet of hosts and routers. We describe an implementation of an ATM network as one link in an ST-2 internet. We explain how the ST-2 owspec is mapped into an ATM hopspec during connection establishment. We then show that, after connection establishment, ST-2 header prediction can be performed on an ATM network to minimize protocol overhead. Finally, we argue that the current ATM adaption layers do not provide the right service for ST-2 or other variable length packet protocols designed to carry continuous media.
