Tracking New Models and Conflicts in Web Interconnection and Delivery

            You might have an interest in my work to understand the diversification of web interconnection and content delivery models, largely driven by the substantial increase in streaming video and the proliferation of Content Delivery Networks.  ISPs have devised many new deviations from the traditional peering/transiting dichotomy including: use of Internet Exchange Points by Tier-2 ISPs, paid peering, CDN surcharges, equipment co-location, e.g., Netflix Open Connect Network; “specialized networks” and Intranets/ Multiprotocol Label Switching and non-carriers like Google securing Autonomous System identifiers.
