Abstract: A communication chip includes a switching (SW) die and a plurality of network processing (NP) dies. Any one of the plurality of NP dies is configured to: receive a first packet outside the communication chip through an external port, obtain destination information of the first packet, and send a second packet including the first packet and the destination information through an internal port. The destination information indicates a destination NP die of the first packet. The SW die is configured to: receive the second packet, and send the second packet to a first NP die in the plurality of NP dies based on the destination information. The first NP die is configured to: receive the second packet, and send the second packet outward through the external port.
