Abstract

The invention discloses a data processing method and device. The method includes the steps that data to be sent issued by an upper layer application are received, and the received data to be sent are cached into a data sending memory pool which is established in advance; if it is determined that a data sending moment arrives according to a set data sending cycle, at least one of the data to be sent cached in the data sending memory pool is written into a data receiving memory pool of a data receiver in an RDMA Write mode. According to the scheme, due to the fact that the RDMA Write mode can be used for writing multiple data cached in the memory pool of a data sender into the memory pool of the data receiver at the same time, the problems that when an RDMA Send mode is used for sending data item by item, the efficiency is low, data can overflow easily and errors can occur easily can be solved, and on the premise that the data sending frequency is reduced substantially and the data overflow probability is lowered, the purpose for improving the data sending efficiency is achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data processing method and device based on RDMA (Remote DirectMemory Access, remote direct memory access) technology. Background technique [0002] RDMA is a remote direct data access technology to solve the delay of server-side data processing in network transmission. It can transfer data from one computer directly to the memory of another computer through the network without any impact on the operating system. Impact, thereby avoiding the process of data copying and text exchange in the external memory, and then achieving the effect of releasing memory bandwidth and shortening the CPU (central processing unit) cycle for improving application system performance. [0003] At present, the data transmission operation modes supported by RDMA mainly include RDMA Send (RDMA sending), RDMA Write (RDMA writing), RDMA Read (RDMA reading) and RDMA Atomic (RDMA atomic oper...
