Abstract

The invention discloses a distributed file system data transmission method based on an RDMA network. The method comprises the following steps: a client receives a file access request from a user; an RDMA connection request is initiated to the server; a server acquires an RDMA connection request from a client and establishes RDMA connection with a client; the client generates a network data accessrequest according to the file access request; the network data access request is sent to a server side by using RDMA connection; and the server analyzes the network data access request to obtain address information in the network data access request, obtains an address of a file corresponding to the address information in the memory of the server as a server return address according to the addressinformation, and sends the server return address and the RDMA remote access permission information to the client. According to the invention, the technical problem of high memory operation overhead in the data transmission process of the existing distributed file system can be solved, and the technical problems of high load and long transmission delay of the server side can be solved.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and more specifically relates to a distributed file system data transmission method and system based on an RDMA network. Background technique [0002] With the rapid development of computer information technologies such as big data, cloud computing, and artificial intelligence in recent years, the scale of global Internet data has grown exponentially, and the demand for high-performance hardware from many high-concurrency and low-latency applications has led to the emergence of high-performance memories. . For high-performance storage, due to its strong I / O throughput on the storage side, the distributed file system needs to allocate more computing resources to complete data processing and data exchange, which increases the transmission delay of the system and limits the network capacity. Transmission capacity and system performance. In order to solve this problem, the Remote Direct M...
