Abstract

The invention provides a data processing method and apparatus. The method comprises the steps of obtaining a data quantity of current to-be-processed data, wherein the current to-be-processed data includes I / O (Input / Output) data for executing RDMA (Remote Direct Memory Access) operation currently; if the data quantity of the current to-be-processed data is greater than a first predetermined threshold, executing the RDMA operation of the current to-be-processed data directly on a page address corresponding to the current to-be-processed data; and if the data quantity of the current to-be-processed data is smaller than or equal to the first predetermined threshold, executing the RDMA operation of the current to-be-processed data on a page address in a receiving device through a pre-established data transmission channel. Through the data processing method and apparatus, the problem of relatively low data processing efficiency caused by the fact that the RDMA operation is executed in a mode of transmitting the data only through multi-time interaction and multi-time copying of a bottom protocol stack in the prior art is solved, so that the effect of improving data processing efficiency is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data processing method and device. Background technique [0002] With the continuous expansion of user data, the rise of information technology. The bandwidth between various communication devices is increasing. A PCIe (PCI-Express) link is widely used as a mainstream high-speed transmission protocol in a node. While continuously improving the bandwidth, the PCIe protocol has gradually begun to step out of the interconnection protocol between the central processing unit (CPU, Central Processing Unit) and external devices in the node, using the non-transparent bridge (NTB, Non Transparentbridge) technology of PCIe, The PCIe protocol can support high-speed interconnection between nodes, and the address domains of interconnected nodes are isolated through NTB. After the address mapping of the NTB, the DMA engine on the local node can access the memory on the peer node by acce...
