Embodiment 1

[0031] figure 2 Shown is the flowchart of the P2P downloading method provided by Embodiment 1 of the present invention, specifically including:

[0032] Step 201. Determine the time taken by the local node to download data of any data amount from each neighboring node.

[0033] That is, when the local node assigns the download task, the data volume of the data to be downloaded corresponding to each neighbor node is randomly allocated, and the time when the data download starts and ends is recorded, so that the time used by the local node to download the data can be determined.

[0034] Step 202, according to the time it takes for the local node to download data of any data amount from each neighboring node, determine the download speed of the local node to download data from each neighboring node respectively.

[0035] The speed at which a local node downloads data from a neighbor node is equal to the amount of data downloaded by the local node from the neighbor node divided...

Embodiment 2

[0042] image 3 Shown is the flowchart of the P2P downloading method provided by Embodiment 2 of the present invention, specifically including:

[0043] Step 301. Determine the time taken by the local node to download data of a preset data amount from each neighboring node.

[0044] That is, when the local node assigns the download task, the data volume of the data to be downloaded corresponding to each neighbor node is the preset data volume, and the downloading time of the local node can be determined by recording the start time and end time of the data download of the preset data volume. The time used by the preset amount of data.

[0045] Step 302 , according to how much time it takes for the local node to download data with a predetermined amount of data from each neighboring node, determine the ranking of download speeds for the local node to download data from each neighboring node.

[0046] The more time it takes for the local node to download the preset amount of da...

Abstract

The invention discloses a P2P downloading method and device. P2P downloading can be used effectively. The P2P downloading method includes the following steps of determining the sequence of downloading speeds at which a local node downloads data from neighbor nodes, and downloading the data from the neighbor nodes according to the determined sequence of the downloading speeds and a set downloading rule, wherein the downloading rule represents that the higher the downloading speeds corresponding to the neighbor nodes are, the higher the emergency degrees of the data download from the neighbor nodes are.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a P2P downloading method and device. Background technique [0002] In a P2P (peer-to-peer, point-to-point) network, each node is an equal peer node, and any node can act as a client or server to other nodes connected to the node, that is, the neighbor nodes of the node. Multiple forms of data, such as video data, audio data, etc., can be shared between nodes. [0003] Therefore, in a P2P network, data downloading methods can include P2P downloading and http downloading. P2P downloading means that the local node downloads and obtains data from neighboring nodes, and http downloading means that the local node directly downloads and obtains data from the server through the http protocol. Generally, the data to be downloaded in the P2P network is generally divided into urgent interval data and non-emergency interval data. For example, when playing a video, the data in a certain int...
