RE: Line rate gigabit router/switch options

[Matthew Huff <mhuff () ox com>]

We currently have 7204VXRs with the NGE-G1 controller. That's rated at 1Gbit/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 something that is hardware switched such as the cisco 
7600/6500 or the Foundry line as some have pointed out.

As far as our netflow requirements are, we need to be able to determine average line rates for different protocols/ and 
different multicast channels (not realtime). We use Fluke Network's NetFlow Tracker and it works with sFlow, IPFIX, 
Netflow and other netflow like protocols, so it looks like almost 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 way.
