Claim 3:
4. The network interface card according to claim 1, wherein
the RDMA operation command is an input/output (IO) read command,
the disconnection event occurs during a period when the first controller sends a middle packet or a last packet of an RDMA write message by using the first shared connector,
the first RDMA message is a second SEND message comprising an IO response,
the IO response indicates a read operation is completed, and
before sending the first RDMA message corresponding to the first QP connection to the host client based on the WQE, the network interface card is further caused to:
send a fake last packet of the RDMA write message to the host client, wherein a payload of the fake last packet is arbitrarily padded, and a packet sequence number (PSN) of the fake last packet is a to-be-sent RDMA packet of the RDMA write message when the disconnection event occurs.
