摘要： A method for video streaming over at least one information-centric network (ICN), comprising transmitting a request for video content to a server, receiving a media presentation description (MPD) file corresponding to the video content from the server in response to the request for the video content, wherein the MPD file identifies names of copies of the video content in the at least one ICN, and wherein the copies of the video content represent different quality levels of the video content, probing the at least one ICN for the copies of the video content by searching the names of the copies, calculating a probability for each of the copies of the video content based on results of the probing, and fetching one of the copies of the video content based on the probability calculated for each of the copies of the video content.

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.

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.
