Highly effective dynamic path analysis method based on ContextFS

Abstract

The invention relates to an efficient dynamic path analytic method based on a ContextFS context file system, comprising the following steps: firstly, a user access preference and a file access behavioral pattern are determined through analysis of historical context information; secondly, a virtual directory path is selected from out-of-order virtual directories according to the file access behavioral pattern and the current user context information; thirdly, the importance degree of files is divided according to a user custom, the user access preference and the file access behavioral pattern; buffer file paths or the files are classified respectively on a mainframe (UH) on which the user is positioned, a metadata server (MS) and a file server (FS); the efficiency of path analysis is improved through a multistage buffer mechanism. The efficient dynamic path analytic method has the advantages that: the virtual directory path is determined by utilization of the file access behavioral pattern and the current context trend, and the multistage buffer mechanism is adopted on the file paths or the files for improving the efficiency of path analysis according to the user custom, the user access preference and the file assess behavioral pattern, thereby the file access performance of the ContextFS file system is improved.

Description

technical field [0001] The invention relates to the path analysis field of a file system, and mainly relates to an efficient dynamic path analysis method based on a ContextFS context file system. Background technique [0002] With the development of computer and network technology, information data has become an extremely critical and important strategic resource in social development. It can be said that information technology has entered the storage era from the computing era with computing as the core. Distributed file system is an important storage system, which plays an important role in data storage, management and sharing. But with the explosive growth of data, a more powerful file system is needed to store, manage, transfer and share files. However, the traditional distributed file system uses a simple hierarchical directory structure to organize files and only supports a small amount of metadata, which makes it increasingly unable to meet efficient file sharing and...

AI Technical Summary

Problems solved by technology

[0003] The ContextFS contextual file system solves the problems that the traditional distributed file system cannot solve (ie, active data service, efficient file sharing and effective unified management), and at the same time, in order to be compatible with the existing file system and applications, and provide the existing distributed file system Comparable performance, the design of the ContextFS file system faces more challenges

Especially since the access of files in the ContextFS file system needs to go through multi-layer operations such as user space to kernel space, virtual directory to metadata server, and metadata server to file server, if the path resolution method is not properly designed, it will seriously affect the performance of the system
