摘要： 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.

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： Aspects of the disclosure provide a network device that includes interface circuitry and processing circuitry. The processing circuitry is configured to receive a first interest packet carrying a first name, add an indicator for routing look-ahead in the first interest packet to generate a first updated interest packet, and select a first entry in a forwarding information base (FIB) based on a lookup in the FIB for matching entries to the first name. The first entry is indicative of an outgoing interface circuit. The processing circuitry is configured to forward the first updated interest packet via the outgoing interface circuit, and receive a data packet in response to the first updated interest packet. The data packet carries forwarding information of devices that forward the first updated interest packet. The processing circuitry is configured to store the forwarding information of the devices in the first entry.

摘要： 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.
