Description
Technical field
The present invention relates to content distribution techniques, relate in particular to a kind of point-to-point (P2P, Peer to Peer) method of content distribution and system.
Background technology
The basic framework of P2P content delivering system is made up of tracking server (tracker) and content distribution nodes (peer), and tracker is also referred to as location-server; Wherein, peer is a peer node, and whole or most of peer are user nodes usually, and tracker is management peer and the server that carries out the peer location.Common P2P content delivering system has BT (BitTorrent), PPLive etc. to adopt the P2P system of proprietary protocol.At present, the standard agreement of P2P content distribution has the Internet engineering duty group (IETF, Internet Engineering Task Force) just at standardized P2P stream media protocol (PPSP, Peer to Peer Streaming Protocol).
P2P content distribution flow has occupied the flow of the Internet significant proportion; Its big flow has brought the network congestion problem; Network congestion influences user P2P content distributing service and other business, the limited service quality that also limits the distribution of P2P content of user uplink bandwidth.The distribution of P2P content combines storage server to address the above problem.Usually such storage server is provided by third party's (normally Virtual network operator), also is called as P2P buffer memory (P2P cache).The distribution of P2P content combines storage server that dual mode is arranged, and a kind of is the Initiative Inventory Management mode, and storage server is supported the P2P agreement, initiatively participates in the content distribution; Another kind is passive storage mode; The utilization of P2P content delivering system is not supported the storage server storage of P2P agreement and is transmitted content; The representative of this type storage server has irrelevant data relaying (DECADE, the Decoupled Application Data Enroute) working group of the application of IETF just at standardized DECADE server.Wherein, passive storage mode does not need storage server to support multiple P2P agreement, does not need storage server to change along with the P2P agreement and revises.
As shown in Figure 1, adopt the P2P content delivering system that utilizes storage server of passive storage mode, comprise content distribution nodes (peer), tracking server (tracker), do not support the storage server of P2P agreement.Wherein, content distribution nodes is used to upload and/or download content; The peer address that the content distribution participated in the tracking server record can also be write down each peer and had which content segments; Storage server is storage of P2P content delivering system and distributing contents.With system architecture shown in Figure 1 is example, and the content distribution operation under the passive storage mode comprises:
S1, content distribution nodes C pass through the distribution crowd that tracking server adds certain content, and report content/content segments that it had to tracking server;
S2, content distribution nodes B pass through the distribution crowd that tracking server adds certain content, and report content/content segments that it had to tracking server;
S3, content distribution nodes B upload content/content segments that it has to the storage server that it connected;
S4, content distribution nodes A inquire about the peer tabulation of downloadable content/content segments to tracking server;
S5, tracking server return the peer tabulation to content distribution nodes A, comprise Downloadable content/content segments information and corresponding peer address thereof in this peer tabulation;
S6, content distribution nodes A are to content distribution nodes C request content/content segments;
S7, content distribution nodes C are to content distribution nodes A returned content/content segments;
S8, content distribution nodes A are to content distribution nodes B request content/content segments;
S9, content distribution nodes B return storage server information (comprising address, authentication information of storage server etc.) to content distribution nodes A;
S10, content distribution nodes A upload the storage server requests content/content segments of content/content segments to content distribution nodes B;
S11, this storage server are to content distribution nodes A returned content/content segments.
Adopt the distribution of P2P content to combine the mode of storage server, make fast, the short time delay of speed that the user downloads content from storage server, the service quality that can obtain; And the same content of storage server can supply repeatedly to download, thereby reduced the flow of user's uploading content.Yet, to adopt in the prior art of passive storage mode, the information transmission of storage server is slow, can not make full use of storage server.As shown in Figure 1; Content distribution nodes (peer) is not knowing that which peer has under the situation of storage server to other peer request contents; If requested peer do not have to be the storage server of its service, then can only obtain content from requested peer, and can not be from other opposite ends the storage server of peer obtain content; This is unfavorable for improving service quality, and this also is unfavorable for reducing the flow of uploading by request peer.This shows that prior art can't make full use of storage server and reduce flow and improve service quality.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment technical scheme of the present invention is further set forth in detail.
Utilize the P2P content delivering system of storage server to comprise among the present invention: at least one tracking server (tracker), at least two content distribution nodes (peer), at least one storage server.
Wherein, tracking server is used for record and has the peer address that maybe possibly have content/("/" expression or) content segments, writes down the said information whether each content distribution nodes that maybe possibly have content/content segments has the storage server of use that has; Tracking server can also the required authentication information of record access storage server.In addition, tracking server also is used to supply the content distribution nodes inquiry can provide or possibly be able to provide the peer tabulation of content/content segments, and indicates the address of each peer and the storage server whether use is arranged in the peer tabulation.
Content distribution nodes is used to upload and/or download content; A content distribution nodes can only be uploaded content, perhaps only downloads content, perhaps not only uploads content but also download content.Content distribution nodes can be uploaded content/content segments to storage server, also can download content/content segments from storage server; Also can directly transmit content/content segments between Peer.
Storage server is used to supply content distribution nodes to upload and download content, and storage server is not supported the P2P agreement.
Storage server can be that the stores service supplier offers the content distribution nodes use.Under this situation; The information that content distribution nodes is grasped the storage server of its use (comprises the address; Also possibly comprise like other information such as authentication informations), and can the information of storage server be offered the other guide distribution node, so that its storage server of other guide distribution node visit.
Need to prove, tracking server or accurately return the peer tabulation that has content/content segments, or return the peer tabulation that content/content segments possibly is provided.The so-called peer tabulation that content/content segments possibly is provided is meant the peer tabulation of participation content/content segments distribution.
For preceding a kind of situation (promptly accurately return have content/content segments peer tabulation), content distribution nodes needs the notice tracking server when the content of this locality storage/content segments increase and decrease, and tracking server is then noted;
For latter event (promptly returning the peer tabulation that content/content segments possibly is provided); Content distribution nodes does not need to report this locality to tracking server and has stored what content/content segments; Only need to report among the distribution crowd who joins certain content/content segments (having also not this content/content segments during report) to tracking server, content distribution nodes can only obtain to have the peer tabulation of this content/content segments from tracking server.Generally; Content distribution nodes obtains to have the peer tabulation of content (possibly not have content fully, have partial content, also have full content) from tracking server; Content distribution nodes is asked self content segments required and that the other side has after the chosen content distribution node inquires that which content segments the other side has from peer tabulation again.
Therefore, content distribution nodes can obtain to have the peer tabulation of (maybe possibly have) content/content segments from tracking server, obtains content/content segments from the other guide distribution node then.In addition, content distribution nodes can be whole contents/content segments, or the part of content/content segments just to certain content distribution nodes request, that is to say that the granularity of request of data is less than or equal to the granularity of data location.
A kind of P2P content delivering system framework that utilizes storage server that the embodiment of the invention provided; As shown in Figure 2, comprise in this framework: tracking server, first content distribution node and upload first storage server, second content distribution node, second storage server of content/content segments.Wherein, With the second content distribution node is the side that desire obtains content/content segments; The first content distribution node is for having required content/content segments one side of second content distribution node; But it will be appreciated by those skilled in the art that any one content distribution nodes in the practical application can both possess the function of first content distribution node, also possessed the function of second content distribution node.In addition, content can be film, music, text, picture etc.; Content segments is the part of complete content, such as a film, a first song a certain section.
In conjunction with system architecture shown in Figure 2, utilize the P2P content distribution method of storage server as shown in Figure 3, mainly may further comprise the steps:
Step 301; Tracking server writes down the address that has content/content segments or participate in the content distribution nodes of content/content segments distribution, and record has content/content segments or whether participation content/each content distribution nodes that content segments is distributed has the information of the storage server of use.
For example: the first content distribution node passes through the distribution crowd that tracking server adds certain content, and reports content/content segments that it had to tracking server; In addition; When the first content distribution node sends content/content segments that it had to first storage server; These content/content segments of first storage server storage; Tracking server writes down first storage server and has above-mentioned content/content segments, and the first content distribution node has first storage server of use.For the other guide distribution node, it can be carried out and first content distribution node similar operation.Thereby; The address that have content/content segments or participate in the content distribution nodes of content/content segments distribution is write down in meeting on the tracking server, and record has content/content segments or whether participation content/each content distribution nodes that content segments is distributed has the information of the storage server of use.
Wherein, Can be that the first content distribution node independently sends content/content segments that it had to first storage server; Also can be by tracking server order first content distribution node content/content segments that it had to be sent to first storage server, can also be that tracking server orders first storage server to ask for content/content segments that it has to the first content distribution node.
Step 302; The second content distribution node has the content distribution nodes tabulation of (maybe possibly have) given content/content segments to the tracking server inquiry; Tracking server returns respective list to the second content distribution node, and indicates that in the tabulation of being returned each has (maybe possibly have) content distribution nodes of given content/content segments whether the information of the storage server of use is arranged.Wherein, possibly have the content distribution nodes tabulation of given content/content segments, be meant the content distribution nodes tabulation of participation given content/content segments distribution.
In addition, the tabulation that tracking server returns to the second content distribution node can be the complete list of tracking server record, also can be the part of the complete list of record.That is to say; In the tabulation that tracking server returns; Can be the information that has a part of content distribution nodes of (maybe possibly have) given content/content segments, can return the information of the full content distribution node that has (maybe possibly have) given content/content segments.
Step 303; The second content distribution node preferentially has first content distribution node request given content/content segments of using storage server in this tabulation; Directly upload the first storage server download given content/content segments of content/content segments, perhaps download given content/content segments via second storage server from first storage server indirectly from the first content distribution node.About direct download or the concrete operations of download indirectly, will in follow-up embodiment, be elaborated.
Need to prove; Second content distribution node among the present invention is after receiving the content distribution nodes tabulation; Whether have the information of the storage server of use, have in the preferential selective listing and use the content distribution nodes of storage server to ask to download given content/content segments according to each that indicate in the tabulation if having (maybe possibly have) content distribution nodes of given content/content segments.Like this; Can guarantee that content distribution nodes is as far as possible from the required content/content segments of storage server download; Reduce the operation of directly downloading content/content segments from content distribution nodes as far as possible; Thereby help making full use of storage server more, and then reduce uploading flow, improving service quality of requested content distribution node.
