A flexible wire-clamping board receives a first unicast packet packaged with a two-layer header, finds that an outbound interface of a next hop of the first unicast packet is located on a Dune switching wire-clamping board, packages a new two-layer header for the first unicast packet according to the next hop of the first unicast packet, packages the first unicast packet packaged with the new two-layer header as a first inter-board communication packet carrying an inter-board communication header and a two-layer PPH header, and sends the first inter-board communication packet to the Dune switching wire-clamping board, the two-layer PPH header of the first inter-board communication packet carrying a physical port identifier corresponding to the first unicast packet next hop outbound interface on the Dune switching wire-clamping board. The Dune switching wire-clamping board receives the first inter-board communication packet, removes the inter-board communication header and the two-layer PPH header of the first inter-board communication packet, and sends the first unicast packet packaged with the new two-layer header via a physical port corresponding to the physical port identifier. |
