Problems solved by technology

In addition, the system does not utilize the existing CDN system and cannot effectively protect the existing investment of operators
In the above scheme 2, the existing CDN has undergone a large-scale transformation, and the investment in transformation is large.
In addition, in order to provide streaming media services for original CDN users and P2PCDN users at the same time, in the backbone network, it is necessary to transmit both traditional streaming media and media content processed by P2P fragmentation, which consumes more backbone network bandwidth
In the above scheme three, each client needs to increase the fragmentation function, and for the same media content, fragmentation is performed on multiple clients, increasing the delay

Embodiment Construction

[0049] The technical solutions of the embodiments of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0050] Figure 4 It is a system general framework diagram of an embodiment of the streaming media information distribution system of the present invention, such as Figure 4 As shown, in the new P2P streaming media content distribution system suitable for operators provided by the embodiment of the present invention, the architecture and functions of the original CDN system are retained at the backbone network level, and multiple autonomous, The mutually independent P2P streaming media networks are P2P autonomous domains; users (Users) in each P2P autonomous domain interact through P2P. At the edge of the network, the traditional media stream is fragmented according to the P2P protocol, and the fragmented media information is sent to the user.

[0051] Figure 5 It is a media stream transmission ...

Abstract

The invention provides a streaming media information distribution system and a method thereof and a user end. The system comprises a content distribution network central node, a content distribution network fringe node and a point-to-point autonomous domain; and the system conducts fragmentation processing to streaming media information requested by a user by a zone central server in the point-to-point autonomous domain or a point-to-point fragmentation module in the content distribution network fringe node and distributes to a user node. The invention takes a content distribution network as core content and point-to-point as the framework of service edge and conducts fragmentation processing to streaming media; and the framework of the system can effectively improve the service capability of the content distribution network without transforming the existing content distribution network or by slightly transforming the existing content distribution network.

Description

technical field [0001] The embodiments of the present invention relate to the field of streaming media communication, in particular to a streaming media information distribution system and method and a client. Background technique [0002] Streaming Media (Streaming Media) refers to the continuous audio / video data stream transmitted and played in chronological order on the data network. Different from traditional playback methods, streaming media does not download the entire file before playing, but only caches part of the content, so that the streaming media data stream can be played while being transmitted, which saves download waiting time and storage space. Currently, streaming media distribution mainly adopts two technologies of content delivery network (Content Delivery Network; hereinafter referred to as: CDN) and peer-to-peer network (Peer-to-Peer Network; hereinafter referred to as: P2P). [0003] A CDN is a distributed media service technology platform based on a ...
