Embodiment 1
[0040] In this embodiment, a data transmission device is also provided, image 3 is a structural block diagram of a data transmission device according to an embodiment of the present invention, such as image 3 As shown, the device includes:
[0041]A preset number of first registers 32 and second registers 34, wherein the preset number of first registers 32 are sequentially cascaded, and the second register 34 is connected to the first-level register 32-1 in the preset number of first registers , the preset number is the number of bytes of the virtual local area network label VlanTag;
[0042] Each first register 32 is used for correspondingly storing a byte of VlanTag, and outputting a byte of stored VlanTag;
[0043] The second register 34 is used to store the input data, and output the input data to the first stage register 32-1;
[0044] Wherein, the data transmission device is used to use the data output by the last stage register 32-n in the first register as the out...
