Embodiment Construction

[0054] 1. System design based on WebSocket:

[0055] The present invention adopts C / S framework, which is divided into server end and client end. A history buffer that stores the global total historical operation sequence is maintained on the server side, and a history buffer of a dynamically changing local history sequence is maintained on the client side. At regular intervals, the server obtains the latest operation sequence from each client, processes it, and returns the largest subset to each client. The information transmitted each time will be guaranteed to be in a small range, which can effectively improve the efficiency of real-time office work.

[0056] Server-side design: use Docker technology to run 3 server-side programs on a physical computer, simulate the distributed services of the cloud environment, use eclipse IDE J2EE as the development environment, deploy the project on tomcat8.0, and access it through the web page .

[0057] Client design: Based on the b...

Abstract

The invention relates to a file management consistency maintenance method in a real-time cloud file-system. A load balancing algorithm is employed for processing mass data efficiently in a cloud environment. When the number of cooperative people is very low, data can be rapidly processed by a server, and the data is directly processed through the server. When the number of cooperative people is high and reaches a set critical value, data is distributed. A plurality of servers work at the same. The servers process the data rapidly and feed back partial processing results to the server for finalprocessing. A COT algorithm is improved to adapt to new centralized architecture in the cloud environment. Unnecessary data transmission is reduced. A relatively high timeliness demand is achieved byreducing query and conversion time. A file model under cloud storage is improved into a cooperative cloud file management system. For three operations: create, delete and rename of a file node in thefile model, the improved COT algorithm is applied to the file management in the cooperative file-system.

Description

technical field [0001] The invention relates to a computer file management technology, in particular to a method for maintaining consistency of file management under a real-time cloud office system. Background technique [0002] The cloud office system allows users in different regions to work collaboratively in the cloud environment anytime and anywhere through the computer network. File management is an important part of the office system. The file management of the traditional office system is generally carried out in a stand-alone environment, and the work efficiency is low. However, using the powerful data processing capability and high efficiency of the cloud, the real-time collaborative file management of multiple people in the cloud environment will be efficient and convenient, such as figure 1 Schematic comparison of single server environment and cloud environment shown. [0003] Real-time collaborative work requires immediate visibility during user interaction, th...
