Abstract: A remote direct memory access (RDMA) data transmission system includes a first network device in a first host and a second network device in a second host. The first network device may create a shared send queue (SSQ) used by a plurality of processes run by the first host, obtain an RDMA data transmission message of a first process from the SSQ, and encapsulate a first identifier corresponding to the first process into a first packet in which the RDMA data transmission message is encapsulated. The second network device is configured to encapsulate the first identifier into a second packet in which a feedback message is encapsulated.
