Abstract
When needing to forward a packet from a switch line card to a programmable line card, the switch line card may encapsulate a pseudo-Layerheader for the packet based on uplink forwarding process of the switch line card. The pseudo-Layerheader may carry an adjacency table index and an egress interface table index which is used by the programmable line card. Correspondingly, the programmable line card may obtain the adjacency table index and the egress interface table index from the pseudo-Layerheader of the packet, and then may re-encapsulate a real Layerheader for the packet based on downlink forwarding process of the programmable line card, and transmit the packet through a corresponding egress interface.
