  • Publication number: 20160255535
    Abstract: Systems, methods, and instrumentalities are disclosed for defining a network specialization mechanism that enables a better alignment between end users' usage profiles and their access networks. Conteni specialization of networks may be implemented as a preference o a particular SCN or network in terms of content. Such a network may, for example, cache in priority preferred content, provide preferential quality of service (QoS), or limit access to non-preferred content. A network may advertise its preference or content specialization to end users (e.g., so that end users can decide to attach to SCNs or networks with compatible preferences) and to other content networks (e.g., to influence content routing decisions or to negotiate partitioning of the specialization space). Such content specialization may apply to physical or virtual networks.
