Abstract
When a first interface board receives from an Ethernet switch chip a first Ethernet data packet, once a destination board of the data packet is determined as second interface board logical device of the first interface board encapsulates the data packet into a PCI-E packet that takes a PCI-E memory space address of a board memory in the second interface board as a destination address, so as to enable a PCI-E Endpoint to forward the first PCI-E packet to a forwarding board of a network device; when the first interface board obtains from a board memory a second PCI-E packet coming from a third interface board, logical device of the first interface board parses out a Ethernet data packet from the second PCI-E packet, and transmits the data packet to the Ethernet switch chip, the third interface board and second interface board being the same or not same.
