Technology providing seamless mobility to mobile processing devices in an Information Centric Network (ICN) is provided. A first point of attachment (PoA) is configured to communicate with a first processing device identified by a device ID and receive content objects addressed to the first processing device. The first PoA is further configured to determine that the first processing device is no longer communicating with the first PoA and moving to a second PoA, and generate a forwarding label identifying the second PoA and the device ID. The first PoA is further configured to append the forwarding label to any content object addressed to the first processing device and not forwarded by the first PoA to the first processing device before it moves, and forward each such content object to the second PoA.

Seamless consumer mobility in information centric networks using forwarding labels

A method performed by a user equipment (UE) for enabling cross-layer receiver oriented dynamic multicast in cellular access. The method includes receiving an information-centric networking content-identifier (ICN-CID) from an application. The method generates a content medium access control identifier (CMAC-ID) using the ICN-CID. The CMAC-ID maps the ICN-CID to a medium access control (MAC) layer.

Enabling cross-layer receiver oriented dynamic multicast in cellular access

Technology for stateless forwarding of packets in an ICN is disclosed. Content routers modify a dynamic filter in an interest packet. In one aspect, a content router extracts a dynamic filter from an interest packet received on an ingress port and combines the dynamic filter with a local filter associated with the ingress port. The packet filter and the local filter may be combined without losing information in the packet filter or the local filter. A new filter may be inserted into the interest packet based on the combined packet filter and local filter. The interest packet having the new filter may be forwarded on an egress port. The data packet that returns the content object for the interest packet may be forwarded statelessly based on the dynamic filter. Thus, the data packet may be forwarded without use of a pending interest table (PIT).

Stateless information centric forwarding using dynamic filters

A method implemented in a network element (NE) configured to operate in an information centric network (ICN), the method comprises creating, by a processor of the NE, a minimum spanning tree for an overlay cluster to which the NE is assigned within a host domain, wherein the minimum spanning tree comprises a root corresponding to the NE and a plurality of member nodes assigned to the overlay cluster, and broadcasting, by a transmitter coupled to the processor, a hash cluster setup (HCS) message to the member nodes, wherein the HCS message comprises source path routing information for the overlay cluster and hop limit values corresponding to distances within the ICN between the NE and each of the member nodes.

Hash-based overlay routing architecture for information centric networks

The disclosure includes a method for an Information-Centric Networking (ICN) network. According to the method, a PoA receives registration information from a producer, where the registration information comprises a name prefix of the producer. The PoA sends a plurality of Border Gateway Protocol (BGP) messages to a plurality of peers of the PoA, wherein at least some of the BGP messages respectively comprise a first mapping between the name prefix of the producer and an identifier of the PoA. By sending the BGP messages comprising the mapping to the plurality of peers, the PoA may efficiently make the plurality of peers to locate the producer.

Distributed producer mobility management in information centric networking

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 method implemented in a network element (NE) configured to operate in an information centric network (ICN), comprising receiving an Interest packet through an interface, wherein the Interest packet comprises an in-packet bloom filter and at least one counting filter associated with an element of the in-packet bloom filter; determining an outbound interface to forward the Interest packet to a next hop in the ICN; selecting a local bloom filter based on a mapping of the interface to the local bloom filter; updating a value for the in-packet bloom filter based on a product determined by a bitwise OR operation of the local bloom filter and the in-packet bloom filter; incrementing the at least one counting filter based on a change to the associated element of the in-packet bloom filter; updating the in-packet bloom filter in the Interest packet; updating the at least one counting filter in the Interest packet; and forwarding the Interest packet through the outbound interface.

Stateless forwarding in information centric networks with bloom filters

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.

Multi-nonce enabled interest packet design for named-data networking

The disclosure relates to technology for forwarding packets in an information centric network (ICN) A first request message, including a first packet filter and a first hop count field that indicates a number of hops the request message has traveled from a requesting node, is received at a node. The first hop count field is incremented at the node traversed by the request message, and the first request message is updated at the node by combining the first packet filter with a local filter, where the combined filter has a length matching a combination of the first hop count field and a length of the first packet filter. The first request message is then forwarded with the combined filter to the next hop node of the nodal path until reaching a destination node with a namespace.

Scalable multicast for notification-driven content delivery in information centric networks

An anchor server in an information-centric network (ICN) receives registration and deregistration requests from one or more producers in the ICN. In response to a producer initially registering, the anchor server stores records associating the producer with content available from the producer via a first point of attachment. In response to the producer deregistering, the records are marked as deactivated. While the records are deactivated, requests for the content from consumers may be queued. In response to the producer reregistering as being connected to the ICN via a second point of attachment, the queued requests are forwarded to the producer via the second point of attachment.

Decentralized, hierarchical, and overlay-driven mobility support architecture for information-centric networks

A network element (NE) includes a receiver configured to receive an Information-Centric Media Access Control (i-MAC) frame, a processor operably coupled to the receiver and configured to determine whether an i-MAC table includes routing information for the i-MAC Based Frame, and a transmitter operably coupled to the processor and configured to route the i-MAC Based Frame based on the i-MAC table when the i-MAC table includes information corresponding to the i-MAC Based Frame, and route the i-MAC Based Frame based on a layer 2 (L2) MAC Address Table when the i-MAC table does not contain information corresponding to the i-MAC Based Frame.

Method and apparatus for an information-centric MAC layer

The disclosure relates to technology providing seamless mobility to a mobile producer node. A request message is received from a requesting node in an information centric network. The request message includes mapping point parameters that have an identifier to identify a mapping server that serves requests targeting the mobile producer node and location-based metrics of the mobile producer node. The mapping point parameters are updated when the mobile producer node moves from a first network component to a second network component, and the updated mapping point parameters are provided to the requesting node in a response message sent from the mobile producer node. The request message may then be forwarded from the requesting node to the mobile producer node using the updated mapping point parameters.
