Abstract
Usage-sensitive charging schemes aim to ensure that connection
charges properly reflect the load imposed on the network. In
multiservice networks the bandwidth and quality of service requirements
of different connections can impose greatly differing loads. With
usage-sensitive charging customers have an incentive to prioritise their
traffic appropriately, and the network operator's revenue should match
the investment required to provide capacity to carry the traffic.
Several charging schemes have been proposed for the Internet and for ATM
networks. The European ACTS project CA$hMAN (Charging and Accounting
Schemes in Multiservice ATM Networks) is studying these issues. CA$hMAN
aims to identify good candidates for ATM charging schemes, develop the
necessary hardware and software facilities to implement them in user
trials, and to use these trials to gain experience of implementation
issues and to acquire user feedback. In this paper we discuss the
important issues attached to usage-sensitive charging and summarise the
research on this subject, review the effective bandwidth and present a
charging scheme suitable for delay-sensitive connections, delay-tolerant
traffic, a unified pricing model and how it is being implemented and
trialled in project CA$hMAN
