Abstract
The present invention discloses a method for retransmitting a data packet in a quick path interconnect system, and a node. When a first node serves as a sending end, only the first data packet detected to be faulty is retransmitted to a second node, thereby saving system resources that need to be occupied in the data packet retransmission. When the first node serves as a receiving end, it implements that the packet loss does not occur in the first node in a case that the second node only retransmits the second data packet detected to be faulty, thereby ensuring reliability of the data packet transmission based on the QPI bus.
