Problems solved by technology

[0003] Switches and routers will route according to the stored routing table when routing. Since switches and routers have routing and data forwarding functions at the same time, limited by the processing power and space storage capacity of the processors of the switches and routers, the routing table only Save the routing information to some switches and routers in its domain. Therefore, it is difficult for switches and routers to choose an optimal path to transmit data packets from the Internet, and it is easy to cause data packets to be transmitted through some switches and routers in a concentrated manner, making the Internet congested.

Abstract

The invention discloses a data transmission method, control plane equipment and forwarding plane equipment. The method includes: receiving a plurality of IP data packets uploaded from forwarding plane equipment; when the destination address of the plurality of IP data packets is the same, selecting a plurality of paths in a routing list for routing the plurality of IP data packets to target terminal equipment corresponding to the destination address; and sending the plurality of paths to forwarding plane equipment, so that the forwarding plane equipment distributes the plurality of IP data packets to the plurality of paths, wherein one IP data packet corresponds to one path, and related information of the corresponding path is attached to the IP data packets. Through the abovementioned method, the data transmission method provided by the invention can realize load balancing of a network, thereby improving network transmission efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication transmission, in particular to a data transmission method, control plane equipment, and forwarding plane equipment. Background technique [0002] The Internet in the prior art is connected by tens of thousands of switches and routers to each terminal device, and the switches and routers route the data transmitted between the terminal devices to realize the interconnection and intercommunication between the terminal devices; [0003] Switches and routers will route according to the stored routing table when routing. Since switches and routers have routing and data forwarding functions at the same time, limited by the processing power and space storage capacity of the processors of the switches and routers, the routing table only Save the routing information to some switches and routers in its domain. Therefore, it is difficult for switches and routers to choose an optimal path to tran...
