ARM (Advanced RISC Machines) platform-based network port extension method, system and equipment and storage medium

The invention provides a network port expansion method, system and device based on an ARM platform and a storage medium, and the method comprises the steps: configuring the ID number of each network port of a two-layer switch chip, after determining a target network port and an external connection network port in the two-layer switch chip, building a corresponding link, and generating a link number, the link number has a mapping relationship with the first ID number of the target network port and the second ID number of the external connection network port, meanwhile, virtual label configuration is performed on the target network port and the external connection network port, and finally, transmission of a data packet on each network port between the two-layer switching chip and the ARM processor is controlled according to the label and the link number, so that each network port is independent, and the data packet transmission efficiency is improved. And the purpose of directional data transmission is achieve
