Hi all, during our last research projects we ran into some problems with the current performance measurement tools like iperf, netperf, and the like. Mostly these tools are not able to schedule a bunch of flows among a number of nodes in a easy way or report more than throughput (e.g., kernel variables like CWND, SSTHRESH). Amongst others flowgrind implements the following features: * Distributed architecture * Sophisticated flow scheduling * Linux kernel TCP statistics * Split control and data connection * Application layer 1-way (IAT) and 2-way (RTT) delay * Customizable socket options * Anderson-Darling statistical test * Monitoring, measuring, and accounting * Rate-limited flows (Uniform and poisson packet distribution) For more information, please check our site: http://www.umic-mesh.net/research/flowgrind/ If you interest in flowgrind you can download there tarball or directly access the code via our subversion repository: svn://svn.umic-mesh.net/flowgrind/trunk Comments and patches are more than welcome! NB: At the moment flowgrind runs only under Linux :-( Alex // // Dipl.-Inform.
