Abstract

Aspects of the disclosure provide an electronic device that includes interface circuits and processing circuitry. The interface circuits are configured to receive and transmit signals carrying packets. The processing circuitry is configured to detect that a received packet includes an Internet protocol (IP) header and an extension header to the IP header and the extension header carries an identifier of an information centric networking (ICN) technology. Further, the processing circuitry is configured to extract the identifier from the extension header, and process the received packet based on the identifier according to the ICN technology. Aspects of the disclosure provide another electronic device that is configured to generate a packet with an IP header (e.g., IPv6 header) and an extension header that carries an identifier of an ICN technology and transmit the packet.

extract the ICN identifier from the extension header, and

when an interest packet for the ICN identifier is determined to be encapsulated in the received packet and when retrieval of a matched content object with a matching name to the ICN identifier fails, update the received packet to become an updated packet by replacing a source IP address field with an IP address of the electronic device, and forward the updated packet via the interface circuitry.

2. The electronic device of claim 1, wherein the processing circuitry is configured to detect that the received packet includes a hop-by-hop option header for carrying the ICN identifier.

5. The electronic device of claim 1, wherein the processing circuitry is configured to:

after the received packet is detected, when the interest packet for the ICN identifier is determined to be encapsulated in the received packet and when the retrieval of the matched content object with the matching name to the ICN identifier succeeds, generate an outgoing packet that includes an IP header and encapsulates the matched content object.

6. The electronic device of claim 1, wherein the processing circuitry is configured to:

after the received packet is detected, when a data packet for the ICN identifier is determined to be encapsulated in the received packet,

extract a received content object corresponding to the ICN identifier from the received packet,

generate one or more outgoing packets that encapsulate the received content object and have one or more respective destination IP addresses different from a destination IP address of the received packet, and

forward the one or more outgoing packets via the interface circuitry.

7. A method for communication, comprising:

receiving signals carrying packets;

detecting, by processing circuitry of an electronic device, a received packet that includes an Internet protocol (IP) header and an extension header to the IP header, the extension header carrying an information centric networking (ICN) identifier; and
