At the data-link layer, ATM o ers a number of features, such as high-bandwidth and per-connection quality of service (QoS) guarantees, making it particularly attractive t o m ultimedia applications. Unfortunately, m a n y of these features are not visible to applications because of the inadequacies of existing higher-level protocol architectures. Although a considerable e ort is underway to tune these protocols for ATM networks, we believe that a new ATM speci c protocol stack i s e s s e n

In this paper we describe the semantics of such a protocol stack, and discuss its advantages over traditional protocol architectures from the perspective of distributed multimedia applications. The performance impact of the new protocol architecture is experimentally demonstrated on a video conferencing testbed built around IBM RS/6000s equipped with prototype hardware for video/audio processing, and connected via ATM links.
