Embodiment Construction

[0034] The basic idea of ​​the present invention is: the three-layer device judges whether the data packet can be quickly forwarded, if yes, rewrites the data packet and forwards it directly; if not, hands over the data packet to the protocol stack for processing and then forwards it.

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] like figure 1 Shown, the method for fast forwarding data packet of the present invention comprises the following steps:

[0037] Step 101: After receiving the data packet, the layer-3 device judges whether the data packet can be fast forwarded, if yes, then execute step 102, if not, then execute step 103;

[0038] Here, the data packet mainly includes: quintuple, virtual local area network (VLAN) value, fragmentation identifier, Internet Protocol (IP) version number, source medium access control (MAC) address, destination MAC address, etc.; whe...

Abstract

The invention discloses a method for rapidly forwarding a data packet. The method includes that a three-layer device determines whether the data packet can be forwarded rapidly, if the data packet can be forwarded rapidly, the data packet is rewritten and then forwarded directly; and otherwise, the data packet is sent to a self protocol stack for processing and forwarding. The invention further discloses the three-layer device for rapidly forwarding the data packet. According to the method and the three-layer device for rapidly forwarding the data packet, repetitive work of the three-layer device for forwarding data packets can be reduced, and the forwarding speed of the data packets can be improved.

Description

technical field [0001] The invention relates to routing technology in the communication field, in particular to a method for rapidly forwarding data packets and a three-layer device. Background technique [0002] The network has increasingly become an indispensable tool in people's daily life. Almost everyone uses the network to query data, send and receive emails, and play online games. Users have higher and higher requirements for data transmission speed. In the network, the data transmission speed depends on the equipment that plays the role of routing, such as three-layer equipment. [0003] At present, a layer-3 device needs to go through a lot of processing to forward data packets. The processing process includes: after the layer-3 device receives the data packet, it first identifies the type of the data packet, records the receiving port number, and then sends it to the protocol stack for pathfinding. , and send the packet after processing is complete. However, typi...
