All,
We're looking into high speed packet capture and analysis systems that can
capture at up to 2.5 Gbit/sec. We'd like to perform a lab evaluation, but
somewhat unsure on how to proceed. I don't believe that an artificial traffic
generator would work, because we're very interested in how the evaluated
products process and index application layer data from rebuilt sessions, and I
suspect that rich content data would be missing from artificially generated
traffic. So, I think that probably leaves us with replaying traffic of existing
captures, and speeding up the replay as necessary to match the peak performance
required. I looked through the Wiki and FAQ on tcpreplay's site, but I'm not
sure if the tips there are complete or current. For instance, it referred to 1
Gbit Intel NICs, but I'll need 10 Gbit NICs to achieve my performance
requirements.
Has anyone successfully used tcpreplay at ~2.5 Gbit/sec or higher rates? If so,
could you please describe your hardware (e.g., 10 gig NICs, storage, CPU, and
quantity of each), and any special OS or tcpreplay tweaks needed to achieve
this? If this is really infeasible using tcpreplay, that'd also be good to
know, along with any pointers towards any alternatives.
Thanks,
Dave Wilburn
