Problems solved by technology
[0004] From the process of forwarding data packets in the above-mentioned prior art, it can be seen that the intermediate routers determine their routing paths according to the IP addresses carried in the data packets. In this way, although all source addresses and destination addresses of the same data flow are the same, the received All routers of these data packets need to analyze the headers of these data packets, determine the next-hop route, and then forward them. The forwarding efficiency of data packets is relatively low

Embodiments of the present invention provide a method, device and routing device for forwarding data packets, so as to improve the forwarding efficiency of data packets. The method includes: receiving a data packet; adding a semantic header on the outer layer of the original header of the data packet, the semantic header includes an identification bit for identifying the data packet as a data packet carrying a semantic mark; if the If the data packet is the first data packet of the data flow, a record about the next-hop route of the first data packet is added in the data record table; and the first data packet is sent according to the next-hop route of the first data packet. The method for forwarding a data packet provided by the embodiment of the present invention avoids parsing the original header of the data packet, thereby shortening the time for forwarding the data packet and improving the efficiency of forwarding the data packet.
Description
technical field [0001] The present invention relates to the field of data communication, in particular to a method, device and routing equipment for forwarding data packets. Background technique [0002] In the field of data communication, a data packet is generally composed of a header (header) and data. Among them, the data belongs to the payload (payload), which is the part that the receiver really needs in the communication system, and the header is to enable the data to be smoothly transmitted from the sender to the Additional information for the receiver, including 5-tuples. The so-called quintuple usually refers to a set composed of source address, source port, destination address, destination port, and protocol type. Take the IP packet as an example, <192.168.1.110000TCP121.14.88.76 80> constitutes a quintuple, 192.168.1.1 is the source IP address, 10000 is the source port, TCP is the protocol type, 121.14.88.76 is the destination IP address, 80 is the destin...
