Message forwarding method, device and equipment based on remote direct data storage

Abstract

Embodiments of the present invention provide a message forwarding method, device and equipment based on remote direct data storage. The method includes: obtaining the message payload corresponding to the RDMA message to be forwarded; using the hardware module in the network card node to encapsulate the message header of the message payload to obtain the processed message; using the network card node The hardware module or software module forwards the processed message. The technical solution of this embodiment realizes the combination of software and hardware for message processing operations, effectively balances the network performance and the flexibility of message processing, helps reduce bandwidth and processor resources, and significantly reduces delay .

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a message forwarding method, device and equipment based on remote direct data storage. Background technique [0002] With the development of network bandwidth and speed, the migration requirements of large amounts of data are becoming more and more extensive, and the growth rate of network bandwidth is much higher than the ability of computing nodes and the demand for memory bandwidth necessary to process network traffic. Data center network The architecture has gradually become the bottleneck of the development of computing and storage technology, and there is an urgent need to adopt a more efficient data communication architecture. [0003] In the process of data packet processing, the traditional TCP / IP technology needs to go through the operating system and other software layers, which requires a lot of server resources and memory bus bandwidth. Copying and moving ba...

Problems solved by technology

[0003] In the process of data packet processing, the traditional TCP / IP technology needs to go through the operating system and other software layers, which requires a lot of server resources and memory bus bandwidth. Copying and moving back and forth between network controller caches puts a heavy burden on the CPU and memory of the server, especially in the face of serious "mismatch" among network bandwidth, processor speed and memory bandwidth, which is more likely to cause network delays Intensification of the effect
