Disclosed are a data packet retransmission method and node in a quick path interconnect system. When a first node acts as a sender, only a first data packet detected to be faulty is retransmitted to a second node, so as avoid repeatedly sending to the second node the first data packet already correctly received by the second node, thereby saving system resources occupied by data packet retransmission, and therefore increasing the utilization of the system resources. When the first node acts as a receiver, a first link layer of the first node buffers a second data packet correctly received within the period from sending of a first retransmission request to receiving of a first retransmission response, and upon correctly receiving a second data packet retransmitted by a second node, sends to a first protocol layer the second data packet buffered during said period, so that when the second node only retransmits the second data packet detected to be faulty, the first node does not lose any packet, thereby ensuring the reliability of QPI-bus-based data packet transmission.
