Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] In the embodiment of the present invention, the transmission of real-time video data is realized through P2P, the nodes in the P2P network system are managed hierarchically, the nodes are divided into transmission nodes, distribution nodes and browsing nodes, and nodes with good network conditions are selected as transmission nodes , provide temporary real-time video data to the browsing node through the distribution node, and the node that has just entered the network is used as the browsing node, and does not provide data sharing services to other video application terminals.

Abstract

The invention is applicable to the field of network communication and provides a P2P (Peer-to-Peer) network system applied to real-time video data transmission. The system comprises a transmission node layer, a distribution node layer and a browsing node layer, wherein the transmission node layer comprises a plurality of transmission nodes, and the transmission nodes are used for transmitting real-time video data in a P2P trunk line, acquiring real-time video data from a video server or upstream transmission nodes and providing branch flow to the distribution node layer; the distribution node layer comprises a plurality of distribution nodes used as downstream child nodes of the transmission nodes, and the distribution nodes are used as the downstream nodes of the transmission nodes and are used for temporarily providing real-time video data to the browsing node layer; and the browsing node layer comprises a plurality of browsing nodes used as downstream child nodes of the distribution nodes, and the browsing nodes are used for being connected with the upstream distribution nodes and acquiring temporary real-time video data. By using the P2P network system applied to real-time video data transmission, the stability and the real-time property of P2P network data transmission and the processing ability for concurrent accesses can be enhanced.

Description

technical field [0001] The invention belongs to the field of network communication, in particular to a P2P network system applied to real-time video data transmission. Background technique [0002] The distribution of existing video data generally adopts the architecture of client / server (C / S). The video collection terminal is responsible for the collection of video data and the encoding of video data, and the video server is responsible for the management of video information collected by the video collection terminal and the video data. For forwarding, the video application terminal communicates with the video collection terminal through the video server, obtains the video data by transferring the video data through the video server, and decodes and plays the video data. The disadvantage of this architecture is that the data source of the video application terminal depends on the data transfer of the server, so the number of concurrency is limited by the processing capacit...
