Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] In order to achieve the purpose of building an optimized P2P streaming network topology, the present invention needs to include two devices, namely: a streaming manager, deployed in each host that joins the P2P streaming network, and these hosts are also called nodes ; and index servers, discretely deployed in the P2P streaming media network, its IP address is fixed, and each node in the P2P network can access these index servers according to the required streaming media files.

[0026] figure 1 is a diagram showing the relationship of devices in the P2P streaming network of the present invention. The two devices are described below.

[0027] Such as figure 1 As shown, the streaming media manager on each host (ie, each node) includes three units, which are respectively a playback unit, an interaction unit and a download unit. exist figure 1 I...

Abstract

The invention discloses a topological construction method of a P2P streaming media network, an indexing server, a streaming media management device and a P2P streaming media network. In order to construct an optimal low latency P2P streaming media network topological structure, the invention provides two methods, i.e. a dynamic neighbor adjusting method and a candidate node selecting method. Meanwhile, the invention comprises two devices, i.e. the indexing server and the streaming media management device at the client terminal, wherein a mainboard of the streaming media management device is arranged to form nodes in the P2P streaming media network. Through communication with the nodes in the P2P streaming media network, the indexing server can collect the present playing positions and loading situations of all nodes so as to assist all nodes to construct the topological structure based on the present playing positions and the loading speed.

Description

technical field [0001] The present invention mainly relates to the P2P streaming media technology, in particular to the topology construction method of the P2P streaming media network, and also relates to the corresponding index server and the streaming media manager in the node. Background technique [0002] P2P streaming media refers to the use of peer-to-peer network (Peer-to-Peer, referred to as P2P) technology, data is transmitted on the network in chronological order and video and audio data streams are continuously played on each host. P2P technology is a technology that directly exchanges information between terminal devices without going through intermediate devices. These terminal devices are nodes, and the relationship between them is equal and directly connected, and each node has the function of information processing and provision. [0003] P2P streaming media technology solves the server and bandwidth bottleneck that traditional client / server (C / S) mode strea...
