Description

A kind of P2P method of content distribution and system
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 EngineeringTask 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.
