To complement what Jared said: The NPE-G1/G2 are software forwarding
platforms, so you get the maximum in flexibility, but the G1 will NOT
give you 1gbit/s of forwarding performance. The G2 is supposed to
(but I've not personally verified that).
The Sup32 will you give >20 Gbit/s hardware forwarding throughput, but
comes with some caveats, like "very slow CPU for anything done in
software", "netflow without TCP flags" and "limited memory for netflow"
(but 1Gbit/s *should* be fine, unless you have extremely high flow
churn).
The NSE-* have hardware forwarding that never really worked, so the
whole product line was abandoned. Short summary. Don't Go There.
