Testing Ethernet Networks for the ATLAS Data Collection System

Overview This paper reports recent work on Ethernet traffic generation and analysis. The paper uses Gigabit Ethernet NICs running customized embedded software and custom-built 32-port Fast Ethernet boards based on FPGAs to study the behavior of large Ethernet networks. The traffic generation software is able to accommodate many traffic distributions with the ultimate goal of generating traffic that resembles the data collection system of the ATLAS experiment at CERN. Each packet is time stamped with a global clock value and therefore one is able to compute an accurate measure of the network latency. Various other information collected from the boards is displayed in real time on a graphical interface.
