Sorry, nope. First, there are multiple systems out there today
that could do this or are close to it. Folks are pretty much there
today with OC-48 interfaces and silicon forwarding, so there is
enough thrust to support a wire speed GigE.
this on multiple interfaces at more than 1 Gbps line rate per interface.
I'm not sure about 10 Gbps line rate today, but in a year or two even on
a 10 GigE interface this should be feasible for multiple equipment
Consider high-speed NAT products as a starting point, because they have
to keep roughly the same state and perform roughly the same functions.
Technology is just not a problem here.
Yes, this is a step up from today's SBR, but the major step up here
is because of the bandwidth, not the added complexity. For folks
with a T1, the cannonical 2600 class machine will still run just
fine. We have an existance proof thanks to NAT.
