The contribution of this paper is threefold. First, we characterize the participants of today's commercial CDN market according to their business model and their set of resources. Second, we use real-world Internet topology data in order to infer CDN infrastructure resources that are associated with market success. Third, we use resource-dependency theory in order to assess if a cooperation of market participants with different business models can change the CDN market concentration based on its resources. Our results indicate that the most successful CDNs use a large number of direct interconnections with networks that are situated close to the content consuming end-customer in order to improve termination quality. Moreover, we can show that White Label CDNs are successful in acquiring the resources that are associated with market success. Finally, our results point out that a large ISP coalition which includes today?s Inhouse CDNs could reproduce the most important infrastructure properties of the current market leaders.
