<p>The embodiments of the present invention provide a method, apparatus and routing device for forwarding a data packet so as to improve the forwarding efficiency of the data packet. The method comprises: receiving a data packet; adding a semantic packet header to an outer layer of an original packet header of the data packet, wherein the semantic packet header contains an identification bit which is used for identifying the data packet being a data packet carrying a semantic mark; if the data packet is a first data packet of a data stream, then adding a record regarding a next hop routing of the first data packet into a data record table; and according to the next hop routing of the first data packet, sending the first data packet. The method for forwarding a data packet provided in the embodiments of the present invention exempts an original packet header of a data packet from parsing, thereby shortening time for forwarding the data packet and improving the efficiency of forwarding the data packet.</p> |
