Abstract
A method for communication link for an access network device. The access network device comprises: a node server, an access switch, and a terminal. The method comprises: the node server requesting for a protocol packet on the basis of a service initiated by the source terminal; acquiring a piece of communication link information of the current service, and the communication link information comprises a piece of communication port information for the node server and the access switch involved in the current service; on the basis of the communication port information for the node server, the node server setting up within an internal data packet address table the port directed by the data packet of the current service; on the basis of the communication port information for the access switch, transmitting to the corresponding accessing switch a port configuration command; on the basis of the port configuration command, the accessing switch setting up the port directed by the data packet of the current service within an internal data packet address table. By means of the present invention, the stability of a transmission channel is ensured, thereby avoiding delays for multimedia services.
