Embodiment Construction

[0046] A robust point-to-point flow scheduling method proposed by the present invention is described in detail in conjunction with the accompanying drawings and embodiments as follows:

[0047] The networking structure embodiment of the method of the present invention is for example figure 1 As shown, 1 to 5 in the figure are all client nodes, wherein 1 is simultaneously a seed client node, a client node providing a media stream, and a client node receiving a media stream; 2 is simultaneously a seed client node and a multicast client End nodes, client nodes providing media streams and client nodes receiving media streams; 3 are multicast receiving client nodes; 4 are both client nodes providing media streams and client nodes receiving media streams; 5 are simultaneously The client node receiving the media stream and the underlying client node; 6 is the route for providing media stream data; 7 is the dispatching server's scheduling of the media stream.

Abstract

This invention belongs to information transmission technique field and relates to a robust flow dispatching method based on point to point. The method is to integrate dispatching server, flow media server and customer terminal points into one living broadcast network gives different definitions to functions in network of each customer points and gives different functions to each customer points in the network. The entrance and exit of the new customer point make changes of the network topological structure and realizes the flow dispatching through network topological form dynamic update and monitoring and part of changing customer point.

Description

technical field [0001] The invention belongs to the technical field of information dissemination, and in particular relates to a highly robust P2P flow scheduling method based on a live broadcast network environment. Background technique [0002] With the development of the Internet, especially the rapid popularization of broadband services, people are no longer satisfied with simple information such as text and images. And there are more and more demands for media services such as video and audio with richer content. Multimedia content in the network, especially continuous media content (video and audio), that is, streaming media content is increasing rapidly. Streaming media is an interdisciplinary subject of multimedia and network communication. In streaming media applications, the content provider splits and packages the compressed video data and transmits it to the receiver through the network in a "stream" manner. The receiver reassembles and decodes the received dat...
