Consumption of multimedia content via the Internet by home users is on the rise. In addition to the delivery via traditional media like TV, many live events are streamed via the Internet. The increased availability of smart-phones, netbooks and high wireless access bandwidth encourages users to consume content on-the-go via mobile technologies. This work identifies requirements necessary to perform internetwork content distribution, proposes a general architecture which fulfills these requirements and gives and discusses an exemplary instantiation of the architecture for Long Term Evolution (LTE) networks. Major focus will be given in this paper in the mapping of a general architecture for interconnected and federated CDNs to the expected and available interfaces in LTE architectures
