Description

A kind of data flow of P2P network and flow metering method

Technical field

The present invention relates to the data flow of a kind of P2P (point-to-point) network and the metering method of flow, particularly relate to the data flow of the P2P network that a kind of multi-source uploads and download and the real time measure method of flow.

Background technology

P2P is Peer to Peer, is called reciprocity connection, peer-to-peer network or point to point network, and the P2P technology mainly refers to form information Control technology after connecting by hardware, and its representative form is a software.P2P originates from initial connected network communication mode, and is interconnected by local area network (LAN) as PC in building, interconnected by the Modem remote dial between different buildings.Wherein be based upon the basis that communication pattern on the ICP/IP protocol has constituted the Internet today, so from the basic technology angle, P2P is not a new technology, but new application technology pattern.Now the Internet is that such application must be provided with a server in network based on the application model of S (Server)/B (Browser) or S/C (Client) structure, and information just can be transmitted by server.Information or concentrate earlier preservations of uploading onto the server, and then download (as the website) respectively, or information press on the server and just can be transmitted mobile (as mail) after proprietary rule (software) processing on network.Nowadays the PC (or operator) that has Napster and ICQ class software just can select another PC (or operator) that has this type of software equally to form interconnected (directly connect, do not pass through server), and both sides' shared resource is worked in coordination with and finished certain action.And have the equipment and the user of same P2P software, can also form one and be its own all P2P private network on the internet.

Nowadays mention the new types of data transmission technology that the P2P technology is meant that more multi-source is uploaded and downloaded.This technology has been utilized the advantage of P2P file transfer technology, the file division that will need automatically to transmit becomes plurality of small blocks, the user can download the different fritters of same file from a lot of individuals there simultaneously, and will " piece together " file that has become last on download person's machine from the blocks of files of various computing machine; When downloading or download finish after, user's computer also just becomes a server, can provide downloaded files piece to other download persons, can have a lot of other users to download same file here from this user simultaneously.In recent years, this technology has been widely used and has been proved to be and can alleviate the pressure of server end significantly and effectively utilize Internet resources, thereby make that downloading large-capacity data at high speed from the public network becomes possibility, the number by this P2P exchange of skills has surpassed 60% of the whole network data exchange in the whole world.

Software is uploaded and downloaded to the most widely used at present multi-source is eDonkey, BitTorrent and the various P2P group utilization that grows up based on DHT.With regard to the agreement of this P2P, the network of two levels is arranged.First level is the network that needs the center node, and the center node is as the information issue source.The needed tracker of BitTorrent agreement, the needed server of eD2k agreement all are the center nodes of first level.The existence of center node is for the tabulation of maintenance customer's information and information retrieval mode more efficiently is provided, yet this still unavoidably wants the technology of centralization.Second level of P2P is the DHT network.DHT is the abbreviation of distributed Hash table, and this is a class is searched node and node information in distributed network a algorithm.Utilize the DHT network, the user can obtain the distributed intelligence of neighbouring node, access network then by a plurality of " by force " node.As long as inserted in the network, or else any one node needs to link any center node or strong node, and only needs toward their neighbouring node to send the request of searching for and obtaining information, just can obtain corresponding information.Certainly, pure DHT web search efficient can be lower than the network that the center node is arranged, yet the DHT network has been represented a kind of more extensive and effective mode of intelligence transmission---according to " Six Degrees " theory, the people that we only rely on us to be familiar with just can find the information that needs.

Unconfined P2P download technology is a kind of double-edged sword, she brings when downloading fast to people and makes the network bandwidth become crowded, make other users be affected with traditional approach file in download or normal web page browsing bandwidth, therefore, Virtual network operator such as Netcom's telecommunications has been done certain restriction to this downloading mode in recent years.In addition, thisly propagate the infringement aggravated copyright easily, countless piracy software and audio-visual works are not added the propagation on the internet of restriction, so WinMX and eDonkey charge by RIAA and be forced to shut down web sites, and more the discussion also launched round copyright.

But, the P2P technology is as the effective solution of the particularly big capacity documents transmission of network file, the vitality that she must be arranged, BitTorrent raises risk investment and prepares to further develop, China home government promotes also to have set up P2P technological associations, and Guizhou Netcom also attempts releasing commercial P2P project.The a lot of businessmans of P2P media play platform are in exploitation at present, the stream media technology of bottom does not have problems, shortcoming is billing interface and management function at present, must accomplish the P2P that can run, this is the problem that operator is concerned about most, this invention is born and has been solved the data flow and the flow metering method of multi-source transmission P2P network just, thereby it is evidence-based to make commercial operation charge, and brings more network operation pattern.

Summary of the invention

The P2P network that the objective of the invention is to upload and download for multi-source provides the metering method of a reliable flow direction and flow.In order effectively to add up the pressure that the flow direction and flow also alleviate central server to greatest extent, the present invention includes:

Each terminal of uploading or downloading is added up the source and the whereabouts of specific file bag;

Each terminal of uploading or downloading uploads to central server to statistical report;

The central server combined data is also finished check and correction;

Central server feedback statistics.

Embodiment

Shown in each figure, there is a statistical server to be responsible for coordinating to download and the statistical system data in the system, the terminal of a series of equities is each users in the system, the carve information of each original document is by a Summary file record.

As Fig. 1, each terminal in the system regularly sends data block information on this terminal to statistical server, tells those data block resources that have which file on this terminal of server.When some terminals (as No. 3 among the figure) when needing file in download, just obtain distributed intelligence from server.

As Fig. 2, after system brought into operation, file was transmitted by being divided into some fritters according to summary, and data can be obtained (as 1,3, No. 5) from central server, and is more then be to obtain (as 1,3,4, No. 6) from other terminals that had related data.Terminal can be downloaded specially not provide and upload (as No. 6), can provide when downloading and upload (as 1,3,4, No. 5), also can provide upload function (as No. 2) when not downloading, even can transmit data (between 3,4) mutually.

As Fig. 3, in the middle of data transmission procedure, the real-time statistics of each terminal is uploaded the flow direction and the flow with the data downloaded bag, when the data download finishes, each data packet group is dressed up a complete file, and generate source, the whereabouts statistical report of packet.Each terminal is aggregated into central server to this statistical report in certain, server by download request, upload mode such as data download coupling contrast and carry out verification and these statisticss are distributed to each terminal.
