Richard Ma - A Macroscopic Model of the Internet Economic Ecosystem

Started with a single best-effort service, the Internet has evolved to an ecosystem where different Service Providers (SPs), e.g., Internet Service Providers (ISPs) and Content Distribution Networks (CDNs) provide different types of services, e.g., IP transit and content caching/distribution. In this work, we propose a preference model on how the Content Providers (CPs) of the Internet choose SPs based on their own characteristics as well as the quality and price of the SPs. Based on the preferences of the CPs and the available set of SPs, our model predicts the collective choices of the CPs and the resulting market share of the SPs. Our model provides a better understanding of the business relationship among the CPs and the SPs, and can help them to make informed decisions so to succeed in this competitive Internet ecosystem.
