I'm gonna have to challenge this bit here, Variola.
Please. Truth requires skepticism. Be bold.
Let's back up. You've got an OC-48 or OC-192 fiber and you want to grab ALL of the data in this fiber. Now I'll grant that in real life there's going to be a lot telephony circuit in there, but let's take a worst-case and assume you need ALL the data.
As cryptographers, we must assume this.
What's in this OC-192? Right now it definitely ain't 10Gb/s of packets. It's going to have LOTS of DS1s, DS3s and, if you're lucky, and STS-3c or two. So you'll need to first of all demux ALL of the tributaries.
Next, you've got to un-map any ATM in each of the DS1s, etc, and then
And how much *dark fiber* is there? Lots and lots, thanks to irrational exuberance. Guess what? SiO2 doesn't care which direction the beam is pumped into. pull
out the IP data from the ATM cells, remembering to reassemble fragmented packets (and there will be plenty with ATM). And remember, you may have to do this for 5000 simultaneous DS1s.
Yawn. You underestimate the Adversary. Never ever do that. Isn't there some chink who wrote that?
Oh, and let's not forget pointer adjustments.
And that's just one fiber. How will you actually get all of this
Oh no, not pointers! What next, MPLS? traffic
back to HQ? Remember, it keeps coming and won't stop.
Dark fiber.
No, I think I'm becomming convinced that they can't yet get ALL of it.
Enjoy your childhood while it lasts. Its a beautiful time.
