The invention relates to a link data transmission method, which comprises that: a user submits an application to a reconfigurable comprehensive management platform, and the reconfigurable comprehensive management platform starts making a link communication scheme and transmits a corresponding member to reconfigurable routers, the reconfigurable router close to a user initiates data transmission at set intervals according the requirements of the user after the member is configured in the reconfigurable routers, the user submits an ending application to the reconfigurable comprehensive management platform after the data transmission is completed, and the reconfigurable comprehensive management platform ends the communication; a path finding agent selects a proper path between the reconfigurable router and the reconfigurable comprehensive management platform; and a loading agent accomplishes data assembly and disassembly. The link data transmission method is flexible in transmission and is suitable for short and rapid data packet transmission to clear destination nodes.
