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 (Diffserv) are a scalable solution to quality of service (QOS) provisioning in the Internet while the numbers of users and high-bandwidth applications increase. However, every few current proposals for Diffserv architectures quantify the service they would provide to applications and the QOS level of the end-to-end service is still unclear. Furthermore, the relationship between network performance, the quality of service that users receive and the tariff that must be paid by the user is not well understood. The aim of this programme is to provide a detailed performance evaluation of current Diffserv models and develop an innovative approach to pricing and resource allocation for differentiated Internet services. Our performance analysis on quantitative QOS will be used to understand the impact of various factors on service level agreements (SLAs), such as network provisioning and traffic engineering. The study on pricing will investigate the implications of pricing as a means of congestion control and the dynamic negotiation of SLAs. We will develop a pricing framework for Diffserv that provides efficient and fair allocation of network resources and is easy to implement in current Internet protocols. Pricing will be combined with other traffic engineering tools (traffic conditioning, QOS routing, etc) to meet contracted SLAs in a cost effective manner.
