Today, a large fraction of Internet traffic is originated by Content Delivery Infrastructures (CDIs) such as content distribution networks and hypergiants. To cope with this increasing demand for content, CDIs deploy massively distributed infrastructures. This poses new challenges for CDIs as they have to dynamically map end-users to appropriate servers, without being fully aware of the network conditions within an ISP network as well as the end-users network location. Furthermore, ISPs struggle to cope with the rapid traffic shifts caused by the dynamic server selection of CDIs. In this chapter, we summarize the ongoing work in this area. We explain the challenges that CDIs and ISPs face separately to deliver the content of popular applications, as well as the opportunities that can be leveraged through different forms of collaboration between content delivery and network infrastructures.
