Problems solved by technology

[0004] For the existing network file system, each operation on the file needs to directly access the remote server, which increases the processing burden of the server, and the smooth access to the file cannot be guaranteed when the network is abnormal, and the stability of file access is poor; at the same time, affected by the network Limitation of transfer speed, unable to achieve satisfactory file access speed

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0023] The present invention mainly increases the local file cache of the client and the local file database of the client between the client and the remote server of the network file system; the local file database of the client saves all the access targets that the user has visited; The client's local file cache saves the access targets that the user has accessed in the recent period; when performing file access, first query the client's local file cache, if it is not hit, then query the client's local file database, if still not hit, then access the remote server; at the same time, keep the access target saved by the client file database consistent with the original user file system saved by the remote server through the synchronization strategy. The...

Abstract

The invention discloses a network file system. The system comprises local file cache, a local file database, a remote server and a client. The local file cache is used for storing access targets which are accessed by users recently, the local file database is used for storing all access targets which are accessed by users and conducting synchronization through a preset synchronization strategy and original user file systems stored in the remote server, the remote server is used for storing original user file systems, when the client is used for determining locations of access targets in accordance with operation commands of users, the client searches in the local file cache, the client searches in the local file database if the client does not search in the local file cache, and the client searches in the remote server if the client does not search in the local file database. The invention also discloses a method for accessing the network file system. By the aid of the method, the interaction of the client and the remote server is reduced, and the file access stability and the access speed are improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network file system and an access method of the network file system. Background technique [0002] A network file system, such as a cloud storage system, refers to a file system in which user files are stored on a remote server, and the client accesses the remote server through the network to perform file operations. [0003] The current network file system generally adopts a simple one-level structure, that is, the client directly interacts with the remote server, and the client’s operation instructions on the file will be transmitted to the remote server through the network, and the remote server will respond and execute it. For example, the client When it is necessary to read a file, it will directly send a file reading command to the remote server, and after finding the corresponding target file from the remote server, pull the corresponding file data.
