You think running a router crashing based on your testing isn't a bug?
That
isn't a bug? What would you call it?

 

Even if the router's max AES throughput is 65mbps (which no one here is
discussing and has nothing to do with the original poster's question),
when
it hit that limit and crashed, that's not a bug?

no one mentioned anything about a bug..

we wanted to see if the 3845 could handle a 100mbps connection. so in
our
lab, we pushed traffic to the 3845. as i stated before, we were
encrypting
the traffic. on demand, we could crash the router. @ ~65mbps, the
router
crashed.

as scott mentioned, one would look at you twice if you tried to use the
3845
on a >100mbps link.

What does a bug in specific code have to do with throughput on that

I've pushed more traffic than that (non-encrypted) on 3845s.

Only hooking up a DS3 to a 3845 is really good for your partner and not
much
else.

The 3845 is faster than an NPE-400. I'm pushing 100mbps on a NPE-400
right
now without any problems. And, not peak traffic load. And, 2 full BGP
feeds.

256mbps of throughput on a 3845??? not likely.

you shouldn't put more than a ds-3 to a 3800. ~50mps is the best the
router
can do wire rate...

i've crashed a 3845 pushing ~65mbps (w/encryption) and i could reproduce
the
crash on demand using a traffic generator.
