You can easily make one-way traffic patterns using nmap. You could use ping -A to do adaptive ping, or ping -f to flood, both of which would help you find out some simple metrics (dropped packets, intervals, pps, etc.).
or You could use Expect to script some common functions, then just run them to generate traffic patterns (e.g. FTP/SFTP/Telnet/SplunkCLI). You could easily script some WGETs or the like as well for HTTP/HTTPS/FTP. Some of the resulting metrics would depend on the servers (how fast they are, how much load they have, etc.). or You could packet sniff some real traffic, then replay them with tcpreplay. This would work for a nework with one piece you were testing (one switch/router/firewall/etc.). --p -----Original Message----- From: NANOG [mailto:nanog-boun...@nanog.org] On Behalf Of Matthias Flittner Sent: Thursday, October 01, 2015 11:21 AM To: nanog@nanog.org Subject: [EXTERNAL]wanted: tool for traffic generation / characteristics / monitoring Dear colleagues, Currently we are looking for a magic tool with which it is possible to generate specific (realistic) traffic patterns between client and server to analyze (monitor) traffic characteristics (jitter, delay, inter arrival times, etc.). It would be good if that wanted tool is not only able to generate different traffic patterns but also is able to collect different traffic metrics over time. So that it is possible to create catchy plots. :) Any hints or links would be greatly appreciated. Thanks in advance. Best regards, -FliTTi
