low-end, freeware, software-based solutions -- check out:
http://www.caida.org/tools/taxonomy/performance.xml
specifically:
- netperf
- ttcp
these can run on *nix boxes. you're bottleneck is the general-purpose
CPU that it runs on, which is a problem for attempting to generate
wire-rate small sized packets, (e.g.: 64, 128-Byte, etc). btw, these
only allow you to run TCP and/or UDP throughput tests -- you can't
generate raw IP packets, if that makes a difference or not. you also
can't randomize any of the header data or set-up semi-predictable,
simulated "flows", like you can with the high-end gear.
high-end:
- Spirent (sp?), a.k.a.: Netcom SmartBits, (they acquired AdTech also)
- Ixia
all have their good and bad points. briefly, the good is: they're
dedicated hardware and they're good at what they do; the downside is
they're can cost you some $$$ depending on quantity and type of
interfaces you're looking at testing. i'd recommend calling their
sales reps so they can give you detailed information and narrow in on
what product/interfaces/packages would be best.
