If I remember correctly from the last time I ran the numbers, the
tech's capacity per cost is compounding at around 40% annually while
the BGP table size is compounding at 20% to 25% annually. Note that
BGP prefix consumption is not growing linearly. It is compounding too,
but at a slower rate than Moore's Law. Those numbers have been more or
less stable across about 15 years. However, in the cost-capacity
calculation there is some intersection between the table size and
sustainable packets per second switching rates. Peak consumption in
packets per second has also been compounding.
