Center node: "network coding meets information centric networking"
  Abstract: The focus of user behavior in the Internet has changed over the recent years towards being driven by exchanging and accessing information. Many advances in networking technologies have utilized this change by focusing on the content of an exchange rather than the endpoints exchanging the content. Network coding and information centric networking are two examples of these technology trends, each being developed largely independent so far. This paper brings these areas together in an evolutionary as well as explorative setting for a new internetworking architecture. We outline opportunities for applying network coding in a novel and performance-enhancing way that could eventually push forward the case for information centric network itself.

Connected through hyperedge HE-1 (induced by source paper "a stable fountain code mechanism for peer to peer content distribution"):

    - "on the benefit of information centric networks for traffic engineering"
    - "contentflow mapping content to flows in software defined networks"
    - "content based traffic engineering in software defined information centric networks"
    - "on the interaction of adaptive video streaming with content centric networking"
