Abstract
The embodiment of the invention discloses a method, a system and a device for realizing content supply. The method comprises the following steps: receiving a content request from a requesting node bya super node; judging whether content requested by the content request is transmitted just now or not by the super node; if so, copying the content, and sending the copied content to the requesting node; if not, searching the content, and sending the searched content to the requesting node. The embodiment of the invention solves the problem of insufficient content supply nodes by arranging the super node which can copy and search the content in an ISP network; in addition, the super node obtains the requested content by copying and searching the requested content and sends the obtained contentto the requesting node, thereby realizing the content supply in the ISP network.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of mthods, systems and devices of realizing that content provides.
Background technology
P2P (Peer to Peer, point-to-point) framework is each side's pattern of client/server each other in a kind of communication network.Because this pattern has reduced the dependence to centralized server, thereby has load balancing, the reliability advantages of higher.Typical P2P uses and comprises file-sharing, and voice sharing and video are shared etc.
The target of P4P is to optimize the utilization of P2P to ISP (Internet Service Provider, Internet service provider) Internet resources, promotes the performance that P2P uses simultaneously.The core concept of P4P is to dispose iTracker (carrier server) in the ISP network, uses reflection network foundation information, for example network topology to P2P, link cost, ISP strategy or the like, the network information that P2P applications exploiting iTracker provides is provided with the P2P session, and for example the source is selected or the like.
In realizing process of the present invention, the inventor finds to exist in the prior art following shortcoming:
In the prior art, at ADSL (Asymmetric Digital Subscriber Line, Asymmetrical Digital Subscriber Line) under the condition of large-scale application, the download bit rate of node is much larger than uploading bit rate, and therefore the node of a request content needs a plurality of nodes that content is provided usually.Great deal of nodes exhausts uplink capability very soon, even meaningfully also can't provide service, and the service ability bottleneck that causes P2P to use.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention provides a kind of method that realizes that content provides, and as shown in Figure 1, may further comprise the steps:
Step 101, super node receives the content requests from requesting node.
Step 102, described super node judge whether to transmit the content that described content requests is asked, if, then duplicate described content, the described content of duplicating is sent to the described request node, if not, then search described content, the described content of searching is sent to the described request node.
The beneficial effect that the technical scheme of the embodiment of the invention is brought is as follows: super node obtains requested content and the content that obtains is sent to requesting node by duplicating and searching, and has realized that content provides.
The another kind that the embodiment of the invention provides is realized the method that content provides, and as shown in Figure 2, may further comprise the steps:
Concrete duplicating with lookup method can occur in the application scenarios of the embodiment of the invention as shown in Figure 3, S1, S2, S3 are super node, U1, U2, U3, U4, U5, U6 are ordinary node, super node and ordinary node all have the topology location information that obtains from iTracker, and super node also has high priority P.
User U5 request content X, at first to appTracker requesting node tabulation, appTracker according to the flow optimization rule of requesting node U5 and with reference to priority P to U5 return node address list, comprise the super node S3 nearest in the tabulation with the U5 physical distance; U5 is to the S3 request content, supposes that S3 is transmitting this content (obtain content and transmit to U4 from U1 and U6), and then S3 is with content replication and be transmitted to U5.
If super node S3 does not transmit requested content, then super node S3 is responsible for seeking content source, and content is transmitted to the user.Super node is sought content source multiple mode, below provides wherein two kinds, notes should not being construed as limiting the invention.
1.S3 to appTracker requesting node address list, appTracker according to the flow optimization of S3 rule and with reference to priority P to S3 return node address list, comprise in the tabulation other super nodes S1 and S2 and with the near ordinary node U1 of S3 physical distance, U2, U3, U4, U5; S3 is to super node S1 and S2 request content, supposes that S1 is transmitting this content (obtain content and transmit to U6 from U1 and U3), and then S1 is with content replication and be transmitted to S3, and S3 is transmitted to U5 with content again.
If S1 and S2 do not transmit requested content, then S3 is to ordinary node U1, U2, and U3, U4, the U5 request content supposes that S3 obtains content from U1 and U2, then S3 is transmitted to U5 with content.
2.S3 to appTracker requesting node address list, appTracker according to the flow optimization of S3 rule and with reference to priority P to S3 return node address list, comprise other super nodes S1 and S2 in the tabulation; S3 to particular super node S2 request content, supposes that S2 is transmitting this content (obtain content and transmit to U2 from U1 and U3) according to the index search algorithm, and then S2 is with content replication and be transmitted to S3, and S3 is transmitted to U5 with content again.
If S2 does not transmit requested content, then S2 is to the tabulation of appTracker requesting node, and appTracker to S2 return node address list, comprises the ordinary node U1 near with the S2 physical distance, U2, U3, U6 according to the flow optimization rule in the tabulation; S2 is to U1, U2, and U3, the U6 request content supposes that S2 obtains content from U1 and U2, and then S2 is transmitted to S3 with content, and S3 is transmitted to U5 with content again.
Receive the node listing request of more users as appTracker after, preferentially return the super node of corresponding optimum and give the user, super node is after receiving these users' content requests, judge oneself whether (or be about to) transmit requested content, if, then with content replication and be transmitted to a plurality of users.
Gradually, super node converges increasing user's request, for wherein identical request, super node only need be sought content source one time, after obtaining content from content source, super node is with content replication and be transmitted to a plurality of users that need this content, thereby has effectively saved the upstream bandwidth of content source (service node).
The beneficial effect that the technical scheme of the embodiment of the invention is brought is as follows:
This programme is disposed the super node that can carry out content replication and forwarding in the ISP network, by cooperating of super node and appTracker, converge and handle the content requests of a plurality of requesting nodes, obtain content from super node or service node, reproducting content, and the content of duplicating is transmitted to all needs this requests for content node, thereby effectively saved the upstream bandwidth of service node, when many more to same requests for content number of nodes, the upstream bandwidth of saving is also just many more, and the uplink capacity of service node is exaggerated many more in other words.On the other hand, because the quantitative requirement of service node is reduced,, optimized utilization to the ISP Internet resources so content replication has also reduced the generation of striding the ISP flow in the up service ability that improves the P2P application.
