Packet sending method and apparatus, and storage device

A storage device comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory and configured to execute the instructions to:
• receive, from a first device and using an RDMA over Converged Ethernet (RoCE) protocol, a first packet;
• obtain, in response to the first packet, a first instant rate of a first queue pair (QP) and a first maximum sending rate of the first QP, wherein the first instant rate represents a quantity of packets that are sent between the first QP and a first QP′ within a unit time, wherein the first QP′ is associated with the first QP, and wherein the first maximum sending rate represents a preset maximum quantity of packets that are allowed to be sent between the first QP and the first QP′ within the unit time;
• identify an adjustment rate of the first QP based on the first instant rate and the first maximum sending rate;
• and
• send, to the first device, a congestion notification packet comprising the adjustment rate.

A computer program product comprising instructions for storage on a non-transitory medium and that, when executed by a processor, cause a storage device to:

• receive, from a first device and using an RDMA over Converged Ethernet (RoCE) protocol, a first packet;
• obtain, in response to the first packet, a first instant rate of a first queue pair (QP) and a first maximum sending rate of the first QP, wherein the first instant rate represents a quantity of packets that are sent between the first QP and a first QP′ within a unit time, wherein the first QP′ is associated with the first QP, and wherein the first maximum sending rate represents a preset maximum quantity of packets that are allowed to be sent between the first QP and the first QP′ within the unit time;
• identify an adjustment rate of the first QP based on the first instant rate and the first maximum sending rate;
• and
• send, to the first device, a congestion notification packet comprising the adjustment rate.
