Embodiment Construction

[0015] The implementation of the present invention will be further described in detail with reference to the accompanying drawings and specific examples. Such as figure 1 Shown is the node join team flowchart.

[0016] A. Nodes join the team and build the team.

[0017] Set the upper limit of the number of team nodes according to the network environment and scale. Each team collaboration node establishes a team information list to store the IP address information of each team member including the IP address information of all members of the team. The request keyword only occupies 1 bytes without increasing network load. At the same time, non-team leading nodes can ignore this request keyword, and its structure is as follows image 3 As shown, the data packet includes an Ethernet header, an IP header, a protocol, a destination IP, a TCP header, and a payload data message format.

[0018] The node requests to join the team, the node adds the request to join the team keyword...

Abstract

The invention relates to a method for improving the downloading efficiency of P2P (peer-to-peer) downloading software by virtue of a teamwork mechanism. The method comprises the following steps of: forming a team by a plurality of P2P nodes for downloading a same file and with the same bandwidth; accumulating uploading traffics of a member node in the team; distributing an uploading traffic value to a node with a maximum uploading traffic value in the team; and in the case that the member nodes in the team upload information, distributing non-blocking to the node with the maximum uploading traffic value in the team, so as to enable the node to have the priority to obtain a downloading resource and enable the member nodes in the team to have the priority to be bon-blocked, to share the downloading resource with the other member nodes in the team by the member node which has the priority to obtain the downloading resource. The method can be widely applied to the existing P2P-type downloading software.

Description

technical field [0001] The invention relates to efficient resource distribution technology in the Internet, in particular to the technology for improving the download efficiency of a P2P file sharing system. Background technique [0002] In recent years, various network applications based on P2P have become more and more widely used, among which the application of file sharing systems with large data volumes such as video and images has the greatest impact, and thus has generated huge network traffic. Effectively improving the file transfer efficiency of the P2P protocol has extremely important practical significance for improving the performance of network services and reducing the load of the network. [0003] Previous studies have shown that strengthening the cooperation between network nodes and fully mobilizing the upload bandwidth of all nodes can effectively improve the download efficiency of the network. The existing main methods for strengthening the cooperation bet...
