- Abstract
- With the arrival of information superhighways, intercontinental ATM WANs become more important for the provision of multimedia applications. An initiative between DeTeBERKOM and the Communication Research Centre (CRC) was undertaken to provide transport protocol, performance characteristics for reliable applications and efficient admission control policies for bundling transport connections. In our work, we investigate practical issues of TCP/IP over Trans-Atlantic ATM and compare them with TCP/IP performance on local area ATM networks. We provide a first glance at TCP/IP measurements over high-speed Trans-Atlantic connection, using national high-speed test networks and Teleglobe's Trans-Atlantic submarine fibre CANTAT-3. Based on scenarios for bulk data and transaction application, we illustrate the specific effects of different performance factors such as: TCP flow control and send window size, network delay, system scheduling and application traffic on the QoS provision in ATM Wan and Lan. We also present the performance effects of bundling transport connections over the same ATM resources. Practical considerations for mapping the application's traffic and QoS requirements to ATM resources are discussed.
