Live broadcast system in peer-to-peer network, and node management method

Abstract

The invention discloses a live broadcast system in a peer-to-peer network. The live broadcast system comprises at least one node and a first server, wherein the first server is used for establishing a connection between the nodes, so that the nodes share node information; and the node is provided with an evaluation module and an elimination module, and the evaluation module calculates and analyzes a health value of the node according to the node information and feeds back the health value to the elimination module so as to select to continue to use or eliminate the evaluated node. According to the live broadcast system provided by the invention, the node with poor quality can be quickly screened and eliminated from numerous nodes, the nodes with good quality are connected to improve the sharing rate of the peer-to-peer network, and thus the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of Internet live broadcasting, in particular to a system and node management method applied to streaming media live broadcasting in a peer-to-peer network. Background technique [0002] Peer-to-peer network transmission technology, that is, P2P (peer-to-peer) technology, is a new type of communication network transmission technology emerging in recent years. It breaks the server / client (C / S) mode of the traditional network in terms of transmission mode, and establishes a direct communication mechanism from client to client. In a peer-to-peer network, each node acts as both a client and a server for others. In a sense, each node is in the same position. The peer-to-peer network is a successful extension of the distributed concept. It distributes the server burden in the traditional way to each node in the network, which can not only greatly reduce the server processing pressure, but also save a lot of CDN tr...

AI Technical Summary

Problems solved by technology

In the existing P2P-based live streaming applications, especially low-latency live streaming applications, the quality of the nodes is more demanding, and the current technology mainly relies on the node management server (tracker) to make recommendations, but the node management The nodes recommended by the server (tracker) cannot maintain good quality at all times. If the quality of a certain node is not high during the playback process, the live broadcast system cannot automatically recognize it and continue to use it, which will lead to a P2P sharing rate in live streaming applications. The overall level is not high, and the efficiency of resource allocation is low, which in turn affects the user experience
