Provided are a method and device for forwarding a data packet. The implementation of the method comprises: a data packet forwarding device receives a data packet, with the data packet being a data packet encapsulated by a communication protocol which requires undamaged and ordered arrival of data packets at the receiving end; the data packet forwarding device judges whether or not the data packet arrives at the data packet forwarding device in accordance with the correct order; if it does not, then the data packet will be stored in a cache queue corresponding to the link to which the data packet belongs; and the data packet forwarding device sends the data packets in the cache queue to the receiving end according to the serial number of the data packet from small to big successively. By way of adjusting the sequence of the data packets before the data packets are sent to the receiving end in the above method, the sending sequence of the data packets is closer to the original sequence thereof, which can lower the disordered sequence rate of the data packets and reduce the problem of bandwidth occupation by the repeated sending of the ACK request and the retransmission of the data packets by the receiving end, thus improving the throughput rate of the network. |
