"what metrics" you want to collect and how to you want to see it
would dictate which apps you'd be using
   - tcp queue/buffers

   - delays
   - retries

xmit/recv buffers in the hardware, default buffers in the OS and
buffers in the software apps must all be tuned to the same gigE

for "catchy plots", you'd want gnuplot so you can (infinitely) zoom in

we use flent heavily in the bufferbloat project for creating traffic
like this and analyzing the resulting jitter, latency, and buffering.

Cisco has an IOS version called Pagent which allows you to craft whatever
traffic types you want (you can even push MPLS labels on the packets if you
want). I've used this in the past for generating client/server traffic
flows and measuring stats on the flows.

RE: wanted: tool for traffic generation / characteristics / monitoring

[Darden, Patrick]

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.).

generating traffic and monitoring traffic is usually not done
by the same apps  there's hundreds of monitoring apps
and hundreds of traffic generators

delay is done very nicely by dummynet in FreeBSD or 
(untested by me ) with NS3 in linux 

i don't understand simulating jitter, but, one can always use 
"delay + random number"

if you want to play with the headers ... that'd imply playing with

"what metrics" you want to collect and how to you want to see it
would dictate which apps you'd be using
- tcp queue/buffers
- dropped packets
- delays
- retries
- udp vs tcp vs icmp vs ...
- stuff ...

xmit/recv buffers in the hardware, default buffers in the OS and 
buffers in the software apps must all be tuned to the same gigE 
or 10gigE speeds otherwise, whacky stuff will happen

for "catchy plots", you'd want gnuplot so you can (infinitely) zoom in 
into the section you want to see dot-by-dot

for big picture ... netstat, ntop, (not much info) mrtg, etc, etc
