In one embodiment, a first node as a source node obtains personal area network identifiers of the first node and a second node respectively; and then fills the personal area network identifiers of the first node and the second node and 6LoWPAN-message-type information in a 6LoWPAN data packet and sends them to the edge router. After receiving the 6LoWPAN data packet, the edge router judges 6LoWPAN-message-type information of the data packet. When the 6LoWPAN-message-type information indicates that the data packet is sent to another 6LoWPAN subnet, the 6LoWPAN data packet is encapsulated in an IP data packet and sent to a backbone network router. The backbone network router and the edge router of the subnet in which the destination node is located, respectively route the data packet according to the personal area network identifier of the destination address. |
