[c-nsp] Opinions of DDoS appliances, other techniques, most notably Cisco Guard

[James Michael Keller]

Yes, I've crushed a MARS 110 unit with netflow data from around 200 
devices.    Cisco recommended we switch to a dedicated netflow collector 
and then feed the consolidated sessions into MARS rather then have MARS 
directly take all the raw netflows (ie layer3 switch flow and router 
flow having duplicate data for the same flow).

We're on the last 5.x build version before 6.x.   Getting ready to 
re-build it from a 6.x disk and see if the new SQL backend helps with 
some of that until we get a dedicated netflow box in.
