Abstract
In a data transmission system, a route information header RIH is added in each transmitted data packet and includes the route information of the data packet in a network. A network element receives the data packet, reads out route information which is needed by a node, and transmits the data packet after the network element reads out the route information which is needed by the node. the route information can be deleted from RIH, and a verification field of the RIH can be updated. The system includes an existing network and a data relay network device, and a data encapsulation protocol of the relay network device for the RIH is associated with the service layer of the original data encapsulation protocol, or is associated with the same layer as an original data encapsulation protocol. The original data encapsulation protocol is used for transmitting in a data relay network device supporting RIH, or is terminated at a boundary of the data relay device at network.
