Abstract: 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).

Abstract: 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.

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.

Abstract: 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.

Abstract: 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.
