The Olympic Service Model: Issues and Architecture

The Olympic Service Model is a proposal for providing service differentiation in the Internet. With this model, those users who pay more receive a higher amount of network resources, based on a three class granularity (bronze, silver, gold). However, the amount of resources received by a user is not specified, and depends on the level of congestion at a given time. In this paper we analyze the validity and limitations of the Olympic Service Model. We then propose an architecture, the SSD architecture, which provides service differentiation according to this model, both for the intra-domain and the inter-domain cases. Finally, we compare via simulation our approach with other existing architectures of the Olympic Service Model.
