Maybe something like EXFO or Anritsu. Spirent and Agilent would be best, but probably too expensive if this is the only use-case.
Anyone out there testing 10gbE with iPerf? If so, what are you using?
Not possible on iPerf. Network testing shouldn't be done with TCP, because then you don't know what you're testing, are you testing TCP stack of the host or network? But writing performing UDP software is quite hard. You cannot use UDPSocket like iperf does, it just does not work, you are lucky if you reliably test 1Gbps. I'm not aware of modern performing UDP testing software, which is shame, because it's possible to do today, it won't be portable and will impose specific limitations on what hardware to use, but it'll be fast and will deliver reliable results and quite accurate jitter measurement. -- ++ytti
