Abstract
The invention provides a method, a device and a system for acquiring media content in a P2P network. The method comprises the following steps: transmitting a request for acquiring node capacity information to one or more peer nodes in a node list capable of providing specific media content; receiving the node capacity information returned by the one or more peer nodes; selecting peer nodes of which the node capacity meets the current downloading requirement as neighbor nodes from the peer nodes which returns the node capacity information; and downloading the media content through the neighbor nodes. The method solves the problem that the starting time delay is long due to extremely long time for looking up the neighbor nodes capable of providing media downloading in the P2P network so as to improve the system service quality and the user experience.
Description
Technical field
The present invention relates to the network technology of the communications field, specifically refer to obtain in a kind of P2P network method, the Apparatus and system of media content.
Background technology
Peer-to-peer network (being Peer to Peer network) is a kind of technology of extensive use on the present the Internet, and it can make full use of the terminal spare capacity is the whole system service.Peer-to-peer network has the multiple network framework, is mainly two kinds of network architectures of structuring and destructuring.In Unstructured Peer-to-Peer Network, comprise LIST SERVER, equipment such as peer node.In the LIST SERVER record network just in shared content, and the peer node tabulation of downloading certain content.Peer node is obtained all or part of download list of object content by LIST SERVER, therefrom chooses to can be used as neighbours and help oneself to finish the node that content is downloaded, and sets up peering session with it and connects.
The P2P Streaming Media claims streaming video again, is a kind of new medium load mode, is specially to adopt the P2P mode to finish the transmission of content in network.P2P Streaming Media transmission means is divided into compressed package one by one with multimedia files such as whole A/V and 3D through special compress mode,, in real time transmission continuous to subscriber computer by video server.The user only need can play behind the multimedia file decompress(ion)s such as A/V, 3D that utilize decompression apparatus to compression on the user's computer and watch through the startup time-delay of seconds or tens of seconds.This transmission means that multimedia file is play while downloading not only makes and starts time-delay shortening significantly, and the demand of system cache capacity is also reduced greatly.
At present new node add request in the P2P network download content 1 start-up course be: new node obtains channel list to channel server, and the sign node starts and begins; New node obtains the part or all of node listing of the same program of request to tracking server; New node is each node acquisition request buffer memory mapping table Buffer Map in node listing respectively; New node is according to the Buffer Map of each node that obtains, and one or more nodes of therefrom selecting at random to have own desired data piece are as neighbor node, and initiates download request to neighbor node, attempts connecting the beginning downloading data block; New node has been downloaded enough number of data blocks, and video playback begins.
In research and practice process to prior art, the inventor finds that there is following problem in prior art: because new node selects the neighbor node request msg to download according to Buffer Map at random, can't guarantee the success rate selected, the neighbor node that causes new node to be asked may be downloaded for it provide data; At this moment, new node connects with regard to needing repeated attempt and the neighbor node that has own desired data piece, can be the neighbor node that oneself provides data to download until finding.Repeat to select to seek in the process of service available neighbor node at new node, consumed the plenty of time, increased to start and delayed time, reduced the system service quality, thereby influenced user's experience with constantly attempting.
