Abstract

Despite the increased bandwidth and the Quality of Service (QoS) capabilities of ATM networks, measurements show that only a fraction of the available bandwidth can be used by applications with current approaches for realizing data communications over ATM employing the TCP/IP protocol suite [1, 2]. This is largely due to the unsuited protocol mechanisms and the lack of QoS support on transport level. Native Mode ATM offers full access to ATM's Quality of Service capabilities in homogenous ATM networks and provides support for a wide range of information streams with different properties and requirements [6]. In order to exploit the capabilities of ATM networks, and to optimally use the available resources, in the network and end system, new transport protocols are inevitable. In this paper we propose the transport protocols ADTS (ATM Data Transfer Service), which uses efficient protocol mechanisms suitable for ATM systems with a minimum of protocol processing overhead. We discuss implementation issues and present performance results obtained with a reference implementation of the ADTS protocol.
