We currently have 7204VXRs with the NGE-G1 controller. That's rated at 1Gbi=
t/s and we aren't running that high yet. What we are running into is micro-=
bursts that overrun the ethernet's fifo buffer due to the cpu routing (even=
though it's CEF based and cisco has verified the configuration). We need s=
omething that is hardware switched such as the cisco 7600/6500 or the Found=
ry line as some have pointed out.
As far as our netflow requirements are, we need to be able to determine ave=
rage line rates for different protocols/ and different multicast channels (=
not realtime). We use Fluke Network's NetFlow Tracker and it works with sFl=
ow, IPFIX, Netflow and other netflow like protocols, so it looks like almos=
t any of the hardware suggested will work.

Hi Matthew,
The Juniper J6350 boxes are both cost effective and are claimed to do line =
2Gbit/s of IMIX traffic I think.
We've several deployed between multitple DCs in Dublin and a load of J4350 =
at different layers. Stick 2GB of ram into each one and they'll go a long w=
ay.
