Pricing for Differentiated Internet Services
As the Internet evolves into a global commercial infrastructure, there is a growing need to support more enhanced services than the traditional best-effort service. Differentiated services are a suitable solution to quality of service provisioning in the Internet while the number of users keeps growing. However, recent advances in differentiated service models have not spawned much work in pricing yet. This is due to the complexity of economic elements involved and the fact that the shape of the differentiated services Internet is still not fully defined. In this position paper, we briefly review the state of the art in this relatively new area and compare some of the main existing pricing approaches. The impact of pricing schemes on differentiated services is emphasized. Based on a discussion of unsolved issues, possible research directions are identified.
