Method and device for accelerating network video downloading

Abstract

The invention discloses a method and device for accelerating network video downloading. The method comprises the steps that fragmenting is carried out on the file code stream of a network video to be downloaded, and fragmentations are placed in a downloading queue according to a playing order from the front to the back, wherein the front fragmentations in the downloading queue are small, and the rear fragmentations are large; at least one fragmentation in the downloading queue is downloaded according to the mode of a preset strategy dispatching dot pair sever and a point-to-point mode. According to the technical scheme, the downloading of an on-line video can be accelerated, enough video data are cached, and smooth playing is ensured.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and device for accelerating network video downloading. Background technique [0002] One of the main applications of the Internet is resource sharing. Users can obtain the required information and data through the Internet, which leads to the concept of downloading, which is a network activity that transfers files through the network and saves the Internet to a local computer. [0003] Taking P2P (Peer to Peer) mode downloading as an example, each node has the same status and assumes the roles of server and client at the same time, that is, when the node acts as a server, it needs to occupy the upload bandwidth. When acting as a client, it takes up download bandwidth. [0004] Currently, many websites provide online videos for users to watch online. Watching videos online is a process of watching while downloading, but in many cases, due to poor network condi...

Problems solved by technology

[0006] On the user's computer, the network bandwidth of different applications is shared. If a program uses bandwidth resources unrestrainedly, the network behavior of other applications will be adversely affected.

In this way, when the download program is running, other network applications (such as browsers, online games, network video or video chat, etc.) also need to occupy network bandwidth, which causes the download program to seize too much network bandwidth, thereby affecting the experience of other network applications phenomenon; for example, when performing a download task, browsing the web will become very slow, online games or video playback will become very stuck, etc.

Existing video accelerators use a single acceleration method, and most of them use multi-threaded downloading from the video server for acceleration. This method has a poor acceleration experience when the network conditions between the local and the video server are limited.
