I have seen a more "optimal" scheme about 15 years ago. Pricing was a
smooth function, but it was for software licensing, not networking.

As I recall, their scheme went something like:
invoice_amount = some_constant * (quantity)^0.75

This seemed smart to me. It gave the customer incentives to invest
more, but also got rid of silly discontinuities that would cause
irrational customer and salesperson behavior.

Has anyone seen something similar in the service provider world? All I
ever see are arbitrary step functions.
