[f-nsp] Jetcore prefix-based?

[Sam Stickland]

Is the Jetcore chipset prefix-based? I've heard some reports that it's
actually flow based but Foundry made modifications to the previous Ironcore
chipset to make it preform like a prefix-based switch?

How will a BigIron 15000 with a J-FxGMR4 preform under a DDOS attack?

I'm also a bit confused as to the differences between the FastIron and
BigIron. They both seem to be Jetcore based and have similar modules numbers
and specs. What are the differences?
