Contextualized information bus

A method for pushing data in a Content-Centric Networking (CCN) network comprises receiving a message from a source at an input interface device of a node device in the CCN network, the node device executing a CCN protocol. A determination is made that the received message is an interest-notification message. The received message is identified as the interest-notification message by including a Type field, a Content Name field, and a Cacheable Object field. The Type field indicates that the received message is pushing data within the CCN network. The Content Name field associates a hierarchical name to the data being pushed within the CCN network. The Cacheable Object field includes a cacheable object representing the data being pushed within the CCN network. The cacheable object is extracted in response to the received message being an interest-notification message. The cacheable object is placed in a cache at the node device.

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.

Probability weighted DASH based video streaming over an information-centric network

A router, and a method of routing an interest packet having multiple nonces in NDN to eliminate stale PIT entries. The method includes a consumer device initially sending an interest packet having a first nonce within a protocol data unit (PDU), the interest packet having a second nonce. A router receives the interest packet and creates a pending interest table (PIT) entry. The consumer device resends the interest packet, the router keeping a single PIT entry per consumer device and using the second nonce to clear PIT entries corresponding to the initial transmission of the consumer device. The first nonce is indicative of requested content from the producer device, and the second nonce is indicative of the consumer device.

A method implemented by a network device residing in a service domain, wherein the network device comprises an information centric networking (ICN) transport layer and a service access layer (SAL) for handling context-aware service logistics and service mobility overlaid on the ICN transport layer, the method comprising receiving, in the ICN transport layer, a message comprising a service request that originates from a user equipment (UE), in the SAL, retrieving, from the service request, contextual information relevant to the UE or an access network connected to the UE, determining, based on the contextual information, one or more services needed to execute the service request, and determining one or more service identities (SIDs) each of which identifies one of the one or more services.

Information centric networking based service centric networking

A method implemented in a content node configured to operate in an information centric network (ICN) comprising allocating each of a plurality of memory spaces coupled to a processor exclusively to a particular thread from a plurality of threads allocated in the processor, wherein the processor is in a content node; assigning each of a plurality of namespaces at a defined level exclusively to one of the particular threads from the plurality of threads based on an assignment algorithm; and partitioning entries from a Forwarding Information Base (FIB) table, wherein the entries map content names to ports on the content node, wherein each entry is partitioned in a FIB sub-table to the memory space allocated to the one of the particular threads associated with the namespace corresponding to the content name contained within the entry.

Balanced load execution with locally distributed forwarding information base in information centric networks

A network element (NE) comprising a receiver configured to receive a flow configuration message from a network controller via an information centric network (ICN), wherein the flow configuration message comprises a flow entry that identifies a flow in the ICN, wherein the flow is associated with a name of an application data object, and wherein the flow entry comprises a forwarding path associated with an application corresponding to the application data object name, and receive a packet, via the ICN, comprising the application data object name, a processor coupled to the receiver and configured to select the flow entry from a flow table based on the packet's application data object name, and a transmitter coupled to the processor and configured to forward the packet along the forwarding path in the selected flow entry.

Software-defined information centric network (ICN)

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.
