Problems solved by technology

[0004] Usually different storage nodes in the same node group are deployed in different computer rooms, and the client and each storage node may also be deployed in different computer rooms. Therefore, when the client transfers files to different storage nodes in a node group, the There will be a large amount of cross-computer room traffic, causing file transfers to be easily affected by network jitter in the computer room, thereby reducing the success rate of file transfers
At the same time, cross-computer room traffic also increases the cost of file transfer

Embodiment Construction

[0076] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0077] The system architecture involved in the file transfer method provided in the embodiment of the present application is firstly introduced below.

[0078] figure 1 It is an architecture diagram of a distributed storage system provided by the embodiment of this application. The distributed storage system includes multiple node groups 100 . Such as figure 1 As shown, for any node group 100 , the node group 100 includes a central node 101 , multiple clients 102 and multiple storage nodes 103 .

[0079] Wherein, the central node 101 may be connected to each storage node 103 in a plurality of storage nodes 103 in a wireless or wired manner for communication. Any client 102 may be connected to any storage node 103 in a wireles...

Abstract

The invention discloses a file transmission method and device and a storage medium, and belongs to the technical field of the Internet. The method comprises: a central node receiving a file transmission request sent by a first client, and the central node sending a storage node list to the first client, so that the first client performs file transmission according to the sequence of all storage nodes in the storage node list. In the present application, when the number of the storage nodes with the maximum weight is more than one, the storage nodes located in the same machine room as the firstclient are ranked in front of other storage nodes. In this way, when the first client tries to perform file transmission in sequence according to the sequence of the storage nodes in the storage nodelist, the storage node which is located in the same machine room with the first client can be tried for transmission, cross-machine-room file transmission can be effectively avoided, the success rateof file transmission is improved, and the flow cost of a network is saved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a file transmission method, device and computer-readable storage medium. Background technique [0002] With the rapid development of the Internet and the widespread popularity of multimedia applications, clients often need to obtain or store a large number of text, pictures, voice, and video files from the data center, resulting in IO (input / output, input / output) load pressure is high. At this time, the data center usually adopts a distributed storage method, that is, the data in the data center is stored in different storage nodes. In this way, each storage node can provide external services, thereby improving the storage capacity, IO processing capacity and rapid response capacity of the entire data center. In this case, how to transfer files to different storage nodes is very important. [0003] In related technologies, a distributed storage system incl...
