A method, device and system for intelligently synchronizing files between the Internet and a local area network

Abstract

The invention discloses a method, device and system for intelligently synchronizing files between the Internet and a local area network, belonging to the communication field. The method includes: obtaining a file list based on the HTTP protocol, parsing and recording files while a client terminal is uploading files to the Internet cloud path to the database; call the API data interface to read the files uploaded within the last N minutes according to the file path; download files concurrently based on multi-threading of the HTTP protocol, and perform segmentation pre-cache synchronization; accept and respond to file processing requests from the job end in the LAN; The device includes a call reading module, a download pre-caching module, a service response module, a cache monitoring module, and a fault-tolerant module; the system includes an operation end and the above-mentioned device (work environment network server) located in the local area network, and the operation end passes through the work environment The network server is connected to the Internet cloud; the invention realizes the intelligent synchronization of files on the Internet and the local area network, and improves the operation efficiency.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for intelligently synchronizing files between the Internet and a local area network. Background technique [0002] For the files uploaded to the Internet by the client terminal, such as pictures and videos, some users need to review a large number of repeated views due to special needs; taking the evaluation of used cars as an example, when customers need to evaluate used cars, they need to take about 20 photos Pictures and videos are uploaded to the cloud server, and the appraiser needs to evaluate the condition and price of the vehicle based on the photos. Because the business has strict requirements on the timeliness of evaluation, every second is very important when an evaluation order is uploaded, but as we all know, the speed of viewing network files is affected by factors such as bandwidth, file size, etc., causing customers to take photos and upload t...

Problems solved by technology

Because the business has strict requirements on the timeliness of evaluation, every second is very important when an evaluation order is uploaded, but as we all know, the speed of viewing network files is affected by factors such as bandwidth, file size, etc., causing customers to take pictures and upload them to the public network (Internet) high-definition files, downloaded and viewed through the existing HTTP (HTTP, Hyper Text Transfer Protocol) protocol network file server, affected by the bandwidth of the work network (LAN), the reading delay during business operations (calculated according to 8M high-definition pictures , more than 3 seconds)

Moreover, all the associated files under each business order cannot be loaded in batches at a time, and the access time of the entire business associated file exceeds at least 1 minute (calculated based on 20 files per order, 3 seconds delay for each access, and high-definition video), Appraisers look at tens of thousands of photos every day, which is completely unbearable, and the appraisal process is divided into three steps. Each photo needs three appraisers to read it separately before the results can be produced, resulting in a slow overall business

[0003] It can be seen that the above-mentioned existing methods and systems for viewing files such as pictures and videos on the Internet have the following defects: (1) the files uploaded to the Internet by the client terminal cannot be quickly synchronized to the local area network; (2) the local area network access file delay It takes more than 3000ms to read the content; (3) Seriously affects the efficiency of business operations
