Analyzing the Interconnection Models of Content Providers
The analysis of the interconnection status-quo between con-tent providers (CPs) and access ISPs is essential to better understand theevolution of the Internet topology. In the last years we have witnessed anincrease in the Internet trac, especially multimedia content, which hasdriven both CPs and access ISPs to rethink their interconnections. Con-tent delivery models, such as employing CDNs or establishing peeringagreements, force tier-1s to reinvent themselves. These changes raise thequestion of what are the interconnection dierences between global andregional CPs. To this end, we collected an extensive data set that allowsus to evaluate the connectivity between a set of access ISPs and the mostpopular CPs for a specic market. Our results conrm that global CPshave a strong presence near or within the access ISPs, while revealingthat smaller or regional CPs orient themselves toward more aordableinterconnection models, such as using CDNs services of tier-1s or hostingproviders.
