Living broadcast model for FBStream flow medium based on P2P network

Abstract

The present invention discloses an FBStream streaming medium live broadcast model based on the P2P network. The invention relates to the technical field of live broadcast of P2P streaming medium. The invention adopts a meshy topological structure which comprises a server 1 which relies a node management module 11 for coordinate the control information between the nodes and a client 2 that is composed of a data buffer zone 21, a caching mapping 22, a data scheduling module 23, a partner management and optimization module 24 and a network interface 25. The transmission of data of P2P streaming stream which has advantages of low time delay and high usage factor of bandwidth of network is realized by optimizing three aspects of node management, data scheduling strategy and partner management on the base of DONet model.

Description

technical field [0001] The invention relates to the technical field of P2P streaming media live broadcasting, in particular to a P2P network-based FBStream streaming media live broadcasting model. Background technique [0002] In recent years, Peer-to-Peer Network (P2P for short) has gradually become one of the hot topics in computer research. P2P technology combines many users into a network, shares bandwidth, and processes information together. Each node in the P2P network is not only a resource or service requester, but also a resource or service provider. The rights and obligations of each node in the P2P network are equal, including communication, service and resource consumption. Introducing P2P into streaming media services can solve the problems of large I / O load pressure, poor scalability and high system deployment costs caused by the traditional C / S model, thereby reducing server load and supporting a wider range of streaming media releases . [0003] Under the ...

AI Technical Summary

Problems solved by technology

In the P2P streaming media on-demand service, users can choose any program in the program list to watch. In the field of on-demand broadcasting, the development of P2P technology is relatively slow. It is the copyright factor of the program source that hinders the P2P on-demand technology

[0005] Although the research on the P2P streaming media live broadcast model has achieved certain results, due to the complexity and dynamics of the network, the streaming media distribution effect of the P2P streaming media live broadcast system has not reached a satisfactory level.
