Provider-Oriented Linear Price Calculation for Integrated Services
نویسندگان
چکیده
When reservation-based service differentiation is offered in an IP network, it is crucial for a network provider to appropriately charge for service invocations. For internal calculation as well as external price representation, a notion of costs and prices for communication services is needed. In this paper, general requirements for cost and price calculation are analysed for packetswitched multi-service networks. We conclude that internal price calculation should be linear, based on resource usage and uniform across multiple service classes. Accordingly, we specify refinements for service class definitions and present a price calculation method for the IETF’s Integrated Services architecture. The application of such a price representation to existing pricing and charging approaches is shown. Finally, certain economic aspects of the Guaranteed service class are analysed and the results are expressed using linear price representation.

Charging schemes are needed to protect an integrated services network from arbitrary resource reservations and to create a funding mechanism to extend network capacity at the most desired locations at the expense of those users that actually use these resources. While not being the only input into pricing and charging, cost calculation is an important part of a charging scheme. In this paper, w...
