the cost of carrying routes

[Ron da Silva <ron () aol net>]

Some ISPs charge for actual bits carried (peak usage, actual count,
whatever) in addition to or instead of per port/circuit charges.

Do any ISPs charge based on the number of announcements a customer
advertises?

If downstream advertisements became mainly smaller prefixes (say /24)
that were not aggregatable by you as their upstream ISP, would you
answer the above question differently?
