...Raising my hand.

My question is on Terry Hartle's comments, maybe someone with more
insight into this could help clear my confusion.

Why would it require to replace every router and every switch when my
understanding is, FCC is looking to install *additional* gateway(s) to
monitor Internet-based phone calls and emails.
In a datacenter you have lines coming in and lines going out. And you
have internal equippment.

You have to eavesdrop on all of this because the supposed terrorist
might come in via ssh and use a local mail programme to send his email.

So you have to eavesdrop on all incoming lines because you dont know
where he comes in. Via aDSL? via cable modem? Via a glass fiber?

And you have to monitor all internal switches because you dont know
which host he might have hacked.

Guess a cheap switch with 24 ports a 100 Mbit. That makes 2.4 Gig.
You have to watch all of these. They can all send at the same time.
Your switch might have 1 Gig uplink. But that uplink is already in
use for your uplink and it does not even support 2.4 Gig.

How about switches used in datacenters with 48 ports, 128 ports, ...
Where do you get the capacity for multiple Gigs just for eavesdropping?

On the other hand - most switches have a port for debugging. But this
port can only listen on one port not on 24 or even 48 of them.

So you have to invent a new generation of switches.

How about the routers? They are even more complicated than a switch.

As everybody should know by now - every router can be hacked. So
your monitoring must be outside the router.

The gouvernment will offer you an *additional* gateway.
I wonder what that beast will look like. It must be able to take
all input you get from a glass fiber. Or do they ask us to get
down with our speed so they have time to eavesdrop.

I can see some sort of
network redesign happening in order to accodomate this but replacing
every router and every switch sounds too drastic, unless I
mis-understood it. Please, I'm not advocating this change but just
trying to understand the impact from an operation standpoint.

Yes, it is drastic. But if they want to eavesdrop that is the only
way to do it.

Any insight will be appreciated.


Here in germany we accidently have found out why east germany had
to finally give up:

They installed equippement to eavesdrop and tape on every single
telefone line. They could not produce enough tapes to keep up
with this :)

Not to mention what happened when they "recycled" the tapes and
did not have the time to first erase them :)

Kind regards,
