The sequence number of the received fourth message data is 10, and is compared with the sequence number of the message data stored in the current minimum physical address, and if the sequence number of the received fourth message data is smaller than the sequence number of the message data stored in the current minimum physical address, the received fourth message data is stored in the minimum physical address, and the physical storage address of the fourth message data is recorded as δ 4=1024, the physical storage address of the received second message data is changed to δ 2= δ 4+30=1054, and the physical storage address of the received first message data is changed to δ 1= δ 2+60= δ 4+30+60 =1024+60 1114; the physical storage address of the received third message data is changed to δ 3= δ 2+20= δ 4+30+20=1024+30+20=1074;

Specifically, when a head pointer and a tail pointer of a memory for receiving messages in the network card are initialized, the head pointer (Ptr _ head) and the tail pointer (Ptr _ tail) are both defaulted to 0, when the CPU is in a message receiving state, a fixed memory is allocated for the network card to directly write the received messages into the memory, the CPU adjusts the value of the tail pointer (Ptr _ tail) according to the allocated memory and informs the network card that the value of the tail pointer (Ptr _ tail) is updated, after the network card receives the messages, the messages are directly written into the memory allocated by the CPU, and the head pointer (Ptr _ head) is controlled to be accumulated. When the head pointer and the tail pointer are equal, it indicates that the memory allocated by the CPU for receiving the message is full, and at this time, the network card controls the tail pointer (Ptr _ tail) of the completion queue to update to the maximum value of the physical address currently storing the received message, and directly writes the tail pointer (Ptr _ tail) value into the memory, and waits for the CPU to read the data of the received message.
