Correct.  We've shown that the growth in the speed of normal DRAM is
slower than the prefix growth rate.  Thus, simply the act of writing
a list of all prefixes to memory (e.g., at initial convergence time)
is taking longer each year.

That, of course, assumes that we *have to* use DRAM. But do we
really have to ?


No, it's not a requirement. If your employer chooses to implement BGP with a disk drive, that's fine by me. ;-)

You can also go in the opposite direction and go to non-commodity memories, but then you go off of the commodity cost curves. Once you do that, it's hard to continue to sustain our growth rate at constant cost, and that's simply another way of failing to scale.
