Description
Technical Field
The invention relates to the technical field of network data processing, in particular to a data processing method and system in a weak network environment.
Background
Education informatization refers to a process of comprehensively and deeply applying modern information technology to promote education reform and development in the education field (education management, education teaching and education scientific research). The technology is characterized by digitalization, networking, intellectualization and multimedia, and the basic characteristics are opening, sharing, interaction and cooperation. The education modernization is promoted by the education informatization, the traditional mode is changed by the information technology, and most of the Internet education systems in the market at present are provided with real-time live broadcast classrooms by carrying software application platforms by hardware equipment such as computers, mobile phones or flat plates and the like. One of the live scenes is a flat classroom scene: the teacher and the students attend class in a flat classroom, the teacher starts live broadcast in the classroom, uploads teaching files and initiates real-time questions and answers or instant tasks, the students download the teaching files through a flat computer, receive the questions and answers tasks to answer instantly, and upload answer files.
The following problems arise in such teaching activities:
1. the problem of slow downloading caused by large downloading flow is as follows:
the PPT or the video needs to be played when a teacher live broadcasts courseware, student terminals need to be watched synchronously, when the teacher pages courseware or plays the video, a student end is triggered to download files simultaneously, the instantaneous flow is high, for example, one file is generally 10KB, 1000 students are 100MB, the corresponding bandwidth requirement is 800Mbps, however, most schools must use an education network, the private installation of broadband is not allowed, the broadband cost of part of areas is high (such as coastal cities like Shenzhe, Guangzhou and the like), therefore, the bandwidth of the schools is very limited, generally about 100 Mbps, the bandwidth is insufficient, the download failure or the download is slow, and the overall class effect is influenced.
2. Too much uploading flow leads to slow uploading and unstable classroom:
teachers can initiate some tasks of doing questions when they are in class, students can upload files such as answers (picture formats) after completing the tasks, and due to the fact that completion time is almost short, broadband uplink flow of schools is small, class connection is easily interrupted, and class taking is affected.
3. The problem of bandwidth waste due to repeated downloading of files is as follows:
as the answers uploaded by the N students are in the classroom, when the teacher cries, the teacher needs to check the answers of the students and needs to download N files, and at the moment, the students also need to synchronize the pictures of the teacher, so that the N x N files can be downloaded. The number of active files is only N, but the traffic of N x (N +1) files is used.
The main solutions to solve the above problems in the current market are 3:
1. the 4G card is used for increasing school bandwidth or mobile equipment. According to the scheme, more cost is required to be invested in bandwidth by a school side, and the threshold of the school hardware environment using the live broadcast platform is improved.
2. The file compression algorithm is researched, so that the file transmission bandwidth cost is reduced: however, file compression algorithms are not uniform, the file compression effect is limited finally, the smaller the compression is, the harder the compression is, and the higher the cost is, and when the number of files is too large, even if the compression algorithm is good, if hundreds of people access together, the flow rate is inevitably increased, the compression needs calculation, the calculation needs hardware support, and the cost is increased.
3. Regionalized deployment of a whole set of live broadcast system: enterprises need to deploy a plurality of servers in each city or area, and the cost investment of hardware, personnel, maintenance, management and the like is greatly increased.

Furthermore, the offline cache server downloads the file data to be used in a certain time from the remote network platform at regular time, and skips the downloaded file data.
The invention also discloses a data processing system, which is characterized by comprising:
the platform data preprocessing module is used for preparing file data required to be used within the stage time in advance; the offline cache agent module is used for downloading and caching the file data, and simultaneously provides a concurrency control function to prevent the same file data from being downloaded for multiple times; the offline uploading module is used for recording the content of the uploaded file data, continuously uploading the file data to a remote network platform at a low flow rate, and uploading the file data on a specified path by using the copy characteristic of the FASTDFS; the offline download management module is used for regularly pulling the prepared data in the platform data preprocessing module and downloading the file data in the data; the offline penetration program server is used for providing service for the offline penetration program client, and the service comprises the step of informing the offline penetration program client to upload specified file data; and the offline penetration program client module actively uploads the file data when receiving the notification of the offline penetration program server.
Furthermore, the offline uploading module records a file data list uploaded by a user, and uploads file data by using a thread pool background with a small number of threads, so that the situation that the file data uploading process does not occupy too much bandwidth is ensured.
The invention has the beneficial effects that: the method and the system for managing the live course application data in the weak network environment are used for classifying the application data, setting response rules, configuring the cache server and concurrently controlling to avoid the waste of bandwidth due to repeated downloading of files, so that a live course is more stable, the hardware cost is reduced and the practical effect is good.
