Flow control functions for high-speed transport protocols in local workstation environments
Maximilian Frank, R. Wittenberg · 2002
We study the impact of the selection of flow control functions in high-speed transport protocols on the performance for both nonbursty client-server traffic and bulk-data communication such as file transfer in a local high-speed environment. Therefore, we consider a workstation cluster based on a FDDI network. Although there are some differences in the behaviour all flow control and retransmission schemes studied (Go back N, Selective Repeat, Selective Retransmission) are able to provide the same performance in the local environment. Here an additionally used rate control scheme is able to reduce a high buffer utilization of a receiving station for a bulk-data transfer without any impact on the transfer delay and throughput. In the conclusion we discuss both functionality and implementational aspects of transport protocols.>
