[c-nsp] NPE-G1 / G2 performance

[Jeff Bacon]

I'm looking for something that can: 

(1) handle about 100mbit (microbursting to gig) of mcast, taking it in
interface A and pushing it out interfaces B and C, and maybe D
(2) sustain 500-800mbit of throughput (assume 100-byte packets,
occasional gig burst) coming in interface B and going out C, just
straight routing
(3) NAT a few TCP streams coming in interface C and going out interface
A, none of which are anything big-shakes (meg or two of throughput)

This is going to be the backup box; the primary is going to be a
cat6500/sup720. I'm trying to avoid buying a second cat6500.

I'm guessing this is beyond what an NPE-G1 can handle. How about a G2? 

If I have to buy an ASR, I'll just buy the 6500; I have a pile of 6500s
and no ASRs.
