Further, the construction process of the first link and the second link in the cross-machine virtual data link is basically the same as the construction process of the first link and the second link in the local virtual data link, and the difference between the two is that when the second link is constructed, the second link in the local virtual data link is directly constructed through the VPP space on the working end server, and the second connection in the cross-machine virtual data link is constructed through the VPP spaces on the two working end servers and the physical switch. The process of constructing the second link may be that the working end server-based user mode switch and the physical switch connect the VPP space on the second network node with the DPDK space on the third network node to form the second link specifically includes: connecting the VPP space on the second network node with the VPP space on the corresponding working server, and connecting the DPDK space on the third network node with the VPP space on the corresponding working server; and establishing a VXLAN tunnel between the VPP space on the working server and the VPP space on the working server corresponding to the third network node through a physical switch so as to form a second link. In addition, the connection modes of the Linux space, the VPP space on the second network node, the VPP space on the working end server and the DPDK space are the same as those in the local virtual data link, and will not be described again here.
