Distributed stream media order system based on P2P technology and implementation method for stream media program order

Abstract

The invention discloses a distributed flow medium order system and realizing method which are based on P2P technique. The invention includes content management subsystem, content exhibit subsystem, log server subsystem, authentication charging subsystem, data Stat. subsystem, P2P CDN network subsystem, flow medium player subsystem. The quantity of servers of system is distributed based on operation requirement to fit for expand and change of server; nodes inform each other data of itself in real time, and exchange online node information in P2P mode, so real time of online node can be increased greatly, burden of longing on server can be decreased.

Description

technical field [0001] The invention belongs to the field of computer multimedia technology and P2P technology, and in particular relates to a distributed streaming media on-demand system based on P2P technology and a method for realizing the on-demand streaming media program. Background technique [0002] Streaming media is a widely popular IP network transmission technology, which sequentially transmits and plays continuous data streams of multimedia content such as audio / video in real time on the Internet. Streaming media technology includes streaming media data collection, audio / video codec, storage , transmission, playback and other fields. [0003] The traditional on-demand system generally adopts the combination of C / S and B / S in the transmission mode. In the B / S mode, the web page is used to publish the movie profile information, and the C / S mode is used for real-time streaming media data transmission. When the user clicks on the specified movie on demand, it will b...

AI Technical Summary

Problems solved by technology

Therefore, the streaming media server and bandwidth that provide the service must increase as the number of users increases, which is undoubtedly a huge investment for operators

[0006] 2. The centralized streaming media server group will put great pressure on the central computer room, network outlet and backbone network, which may cause performance bottlenecks and lead to QOS decline

[0007] 3. The traditional centralized on-demand system is likely to cause a single point of failure, causing the user to pause the screen when ordering, or even fail to order

Although it is possible to avoid stand-alone failures by adding servers, the screen pause caused by large network bandwidth fluctuations still cannot be solved

[0008] 4. For popular movies, due to the large number of people ordering the same file at the same time, the on-demand server is likely to be full

Although the hardware investment is huge, the service capability of the system is always limited

Especially in some special cases, such as real-time broadcast of sports games, theatrical performances, popular movies, etc., it is easy for the streaming media server to be full, and it is difficult to meet the intensive and sudden on-demand requests of users.

[0009] 5. Expensive servers, bandwidth and content distribution system (CDN) lead to high cost of streaming media business, so it is difficult to reduce the cost of watching streaming media programs

This will lead to the rapid spread of online piracy represented by BT, which will hinder the further development and prosperity of the streaming media business to a large extent.
