摘要： Various disclosed embodiments include methods, systems, and computer-readable media for named data network (NDN) inter/intra-domain mobility. A complete de-coupling of identity and addressing space is established. This provides separation of control and forwarding allowing rich policy based routing, using SDN principles, as well as policy based global resolution. In one embodiment, the de-coupling of identity from location is achieved by a changeable forwarding label field in a header that can have nodal/domain/global scope. This disclosure provides content routing/mobility to be handled with a high degree of flexibility. This disclosure also provides mobility as a service for a component of a name space.

摘要： Various disclosed embodiments include methods, devices and systems establishing secure discovery and secure communication in an ad hoc information-centric network (ICN). An application in a consumer device sends a discovery interest including an associated service name or prefix encrypted by an encryption key using the ICN. A producer device publishing and discovery protocol (SPDP) on an ICN stack of the producer device receives the discovery interest and verifies the consumer device using the encryption key. The producer device SPDP returns a data protocol data unit (PDU) to the consumer device configured to enable the consumer device to access the published service, and the consumer device establishes routing with the producer device and receives the local published service.

摘要： A flow-driven forwarding strategy includes receiving an Interest packet, where the interest packet includes a flow state indicator. The content associated with the Interest packet is checked to determine whether that content is locally stored. Another check is performed to determine whether any previously received Interest packet has requested the content. In response to the content not being locally stored and no related Interest packet has been previously received, the flow state indicator is checked in the Interest packet. In response to the flow state indicator indicating that the Interest packet is associated with an active flow, forwarding information is extracted from a flow state table if a hop count has a value of zero or from the Interest packet if the hop count has a value greater than zero. The Interest packet is then forwarded to a next hop in accordance with the forwarding information.
