Embodiment Construction

[0044] Figure 1 ~ Figure 3 is an embodiment of the present invention. The technical solution proposed by the present invention will be further described below in conjunction with the accompanying drawings.

[0045] Such as figure 1 As shown, a P2P network-based FBStream streaming media live broadcast model adopts a mesh topology, and the FBStream model is divided into a server end 1 and a client end 2.

[0046] A kind of server end 1 based on the FBStream model of P2P network described in the embodiment of the present invention coordinates the control information between nodes by the node management module 11, mainly completes the following functions:

[0047] (1) Maintain and update the list PeerList of all nodes, in which the node list PeerList (Node_ID, Info, time) is mainly composed of three parts: Node_ID marks the node as unique, node information Info (including node IP) and node joining time time;

[0048] The maintenance node list PeerList information described in ...

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 ...
