Abstract

The invention discloses a method and a system for shortening time delay in a peer-to-peer network streaming media live broadcast system. The system is provided with a media source node and a cache routing server, wherein the media source node is used for the media resource management of the whole system; the cache routing server is used for media resource management, routing calculation and peer client end management in a local domain; the cache routing server is used for selecting a proper peer client end from other managed peer client ends and establishing streaming media data interaction with a request peer client end; when needed media streaming data does not exist in the peer client end managed by the cache routing server, the cache routing server is used for requesting needed streaming media data information from other cache routing servers and transmitting the needed streaming media data information to the request peer client end; and when the cache routing server is failed forobtaining the needed streaming media data from other cache routing servers, the cache routing server is used for obtaining the needed data from the media source node and transmitting the needed data to the request peer client end.

Description

technical field

[0001] The invention relates to the technical field of network streaming media, in particular to a method and system for reducing delay in a peer-to-peer network (P2P, peer-to-peer) streaming media live broadcast system. Background technique

[0002] With the development of the Internet, it has become a hotspot to use the network for streaming media playback. Streaming media refers to multimedia that uses streaming technology on the Internet (Internet) / Intranet (Intranet).
