Web Cache charging policies

CHARGING POLICIES FOR NON-ISP'S CACHE SERVERS

non-measurable profits (changing of external/internal traffic rate, customers comfort)
measurable profits: savings on external link's bandwidth

PROFIT = (W3C <-> customer) - (W3C <-> WAN)

ISP clients do not pay for traffic between the and web cache server (because it's internal in local ISP structure)
ISP and W3C provider share the profit from traffic reduction -

W3C provider does not charge cache clients, but cooperating ISP

WEB CACHE IN ISP STRUCTURE AND BILLING

before IPv6 there is no good mechanism for billing
you could have an abonament for users will independent services (like DNS) and billing for data requested by user such as WWW objects
you could enforce users for using web cache and charge them for WWW requests using web cache server's logs for accounting
