Abstract
TCP congestion control methods seriously and unnecessarily harm performance of network transmissions when used in dedicated clusters and grids. We present a simple method in which congestion control can be disabled under appropriate circumstances while still addressing fairness issues and avoiding congestion collapse. We discuss a Linux-based implementation of this “Rude TCP ” 1 and demonstrate the performance benefits this change provides over one and ten gigabit Ethernet links in Linux – showing a factor of 20 improvement in some cases.
