wanted: tool for traffic generation / characteristics / monitoring

[Matthias Flittner <matthias.flittner () gmail com>]

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,
