Problems solved by technology

Since the step of searching network files is generally time-consuming, about 30 seconds to 1 minute, or even more
The client must wait until the search returns the results to determine the address of the obtained file and then download the file. During this period of time, the user can only wait. For applications that require real-time playback, especially network video files, users hope to reduce Start-up time, the start-up time of the existing P2P system affects the user's experience and acceptance of online video file playback, which in turn hinders the development of online video applications

Embodiment 1

[0030] Assume that the upper limit of the number of predictive searches set by the system in this embodiment is 5, such as figure 1 As shown in , the user browses the webpage containing the video file and views the video of interest. At this time, the computer system of the client side performs the following predictive search work;

[0031] a) analyze the HTML language content of the webpage, and utilize the HTML language markup feature to analyze the link information included. This embodiment only obtains the links of all playable video data files existing in the webpage, and these links form a link set L.

[0032] b) In the link set L, extract the video file information in the link to obtain the set F; the video file information includes the name, format, server address, etc. of the video file.

[0033] c) In the set F, do predictive analysis, select some links in the webpage to form a predictive request set S for searching in advance;

[0034] In this embodiment, the numbe...

Embodiment 2

[0048] Embodiment 2: Other steps are the same as Embodiment 1, the difference is that the video files for prediction search and transmission are audio files.

Embodiment 3

[0049] Embodiment 3: Other steps are the same as Embodiment 1, the difference is that the video files for prediction search and transmission are streaming media files.

Abstract

The related network file transmission method based on predictive search comprises: in P2P system, before sending request, taking predictive analysis according to current client feature information; when sending request, matching predicted result to locate and acquire file. This invention can reduce user download time.

Description

technical field [0001] The invention belongs to the field of network transmission, and in particular relates to a network file transmission method based on predictive search. Background technique [0002] With the development of network bandwidth and network applications, network files, especially media files with large data volume, are becoming more and more popular in the network. For example, many websites provide a large number of video-on-demand, live broadcast applications, multimedia magazines and newspapers, flash animations, Even online games, software distribution and other applications. Among them, the development of network video applications is the fastest, and a large number of network TVs such as IPTV are being built, and podcasting is a more extensive network application for netizens to exchange video files. [0003] In the existing technology, users want to play video files in the network smoothly in real time and download network files quickly. The traditi...
