<p>A method for realizing flexible QinQ includes: after receiving a message, looking up corresponding Media Access Control (MAC) address items of the message in a MAC address table, if the corresponding MAC address items are found, performing flexible QinQ transformation for the received message according to the flexible QinQ information included in the MAC address items, and transferring the message after completing the flexible QinQ transformation. The present invention also provides a device for realizing flexible QinQ and a QinQ transformation board. The present invention gets rid of a network processor with expensive cost, enables the storage of the flexible QinQ information and rapid transferring of the message just on a simple interface board, overcomes the problem in the prior art that the speed for searching mass QinQ items is slow, and enlarges the profits of operators and network product users.</p> |
