Peak or average? Think twice before answering. :-)

I'm told there are 6to4 relays seeing in excess of 100mbps. Not bursts.
Can you imagine trying to handle 100mbps "internet mix" traffic process
switched? :-Z Not even talking about the peaks.

That's a trivial op, and the Tunnel PIC sees the L3 header anyway so
can easily take it from there.

But I fear that feature hasn't made it to the RFPs and otherwise "high
profile much revenue anticipated" feature request lists yet, so we'll
have to wait. :-(
