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.
