[Codel] Network test tools for many parallel/concurrent connections?

[Jesper Dangaard Brouer]

(I'm testing fq_codel and codel)

I need a test tool that can start many TCP streams (>1024).
During/after the testrun I want to know if the connections got a fair
share of the bandwidth.

Can anyone recomment tools for this?

After the test I would also like to, "deep-dive" analyse one of the TCP
streams to see how the congestion window, outstanding-win/data is
behaving.  Back in 2005 I used-to-use a tool  called
"tcptrace" (http://www.tcptrace.org).
Have any better tools surfaced?
