Abstract

The invention discloses a data transmission method and device and a computer storage medium, and belongs to the technical field of communication. The method comprises: a receiving queue being configured in a receiving end, the receiving queue comprising N memory blocks, one memory block being used for caching one data unit, and N being a positive integer larger than 1. According to the embodimentof the invention, a receiving queue with a fixed capacity is configured at a receiving end. When the receiving end receives one or more data units sent by the sending end, each data unit is cached ina memory block in a receiving queue, and the receiving end sends the notification message to the sending end in time, so that the sending end can send the data unit according to the number of the idlememory blocks, the sending end does not need to send a memory application request to the receiving end before transmitting data each time, and thus frequent interaction between the receiving end andthe sending end in the data transmission process is avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data transmission method, device, and computer storage medium. Background technique [0002] With the development of communication technology, different computers can use RDMA (remote direct memory access, remote direct memory access) technology for data transmission, which can realize the direct transmission of data from the memory of one computer to the memory of another computer, The CPU (central processing unit, central processing unit) on the computer does not need to intervene, thereby effectively solving the delay problem in the data transmission process. [0003] In related technologies, when using RDMA technology for data transmission, if the memory at the receiving end enters the data transmission state before it is ready, the probability of delay in receiving data at the receiving end will greatly increase, greatly affecting data transmission per...
