Claim 11:
12. A message sending and receiving method, comprising:
receiving, by a parser, a first send (SEND) message from a host client, wherein the first SEND message corresponds to a first queue (QP) connection;
distributing the first SEND message to a first shared connector, wherein the first SEND message includes a remote direct memory access (RDMA) operation command;
initiating, by the first shared connector, a corresponding RDMA operation according to the RDMA operation command to access an internal memory of the host client;
obtaining, by the first shared connector according to the RDMA operation command and a current stage of the RDMA operation, non-volatile memory express (NVME) information sent to a first controller and corresponding to the first QP connection;
enabling a second controller to obtain the NVME information by interacting with the second controller when a disconnection event of a link between the first shared connector and the first controller is detected;
obtaining a work queue element (WQE), from the second controller, based on the NVME information; and
sending a first RDMA message corresponding to the first QP connection to the host client based on the WQE.
