Description

A kind of method that realizes the P2P stream media system based on the bandwidth guarantee technology
Technical field
The present invention relates to a kind of implementation method of Streaming Media, more particularly, relate to a kind of mode that relies on the optimization server data to provide and improve the method that the P2P technology realizes stream media system.
Background technology
1.P2P the stream media technology introduction
The stream media technology of current P2P is paid attention to by people, and its main occupation mode comprises software loading, the registration of server end information, obtains media resource information, and realizes interconnection, transfer of data and further buffered play.This technology has two aspect advantages:
A, do not need the support of internet router and network infrastructure, so cost performance is high and be easy to dispose;
B, Streaming Media user be downloads of media stream just, but also upload Media Stream to other users, therefore, and can the extend one's service scale of group of this method, and bring more resources by more demand.
The network configuration of P2P stream media system, most of system can classify as method or the notion of setting in the computer theory.In this method, node is organized into the topology (normally tree is as shown in Figure 1) of certain transmission data, and each packet all is transmitted on same topology.Node on the topological structure (peer) has the clearly relation of definition, for example, and " father node-child node " relation in the tree structure.This method is typical method for pushing, receives packet when node (peer) that is:, and it just is forwarded to the copy of this packet its each child node.
Among Fig. 1, above father node in the network structure, the just top of whole tree; We are referred to as the father node server; Remaining child node, the branches and leaves part of just setting, we are referred to as peer or peer server; Each peer is that the mode by " c/s pattern " client-server coexistence exists, and has not only downloaded but also provide download.
2.P2P the key technology in the Streaming Media
Because there is unsteadiness in node in the P2P stream media system, so the P2P stream media system need be selected to have breakthrough aspect technological, fault-tolerant and the security mechanism at Media Stream location technology, node.
A, Media Stream location: based on the P2P demand stream media system of catalogue, the mode of searching of its media file is to safeguard all media server information and customer information (comprising IP address, buffer size etc.) through LIST SERVER.When new client's request arrives, the media file of search request in catalogue, fast return candidate node, candidate node can be media servers, can be the clients that this filmstrip can be provided also, thereby have the characteristic of P2P.
The selection of B, node: in a typical P2P overlay network, the node in the network is from each different autonomous territories, and node can freely add or leave overlay network the time in office, causes overlay network to have very big dynamic and uncontrollability.Therefore, how when service conversation is initial, confirm that a metastable service node or a node set that provides certain service quality (QoS) to guarantee is the problem that the P2P stream media system presses for solution.
C, fault tolerant mechanism: because the dynamic of node in the P2P stream media system is providing the node of service may leave system, transmission link also possibly lose efficacy because of congested.In order to guarantee the continuity of the service that receives, must take some fault tolerant mechanisms to make the unaffected or recovery as early as possible of service ability of system.
D, security mechanism: network security is the basic demand of P2P stream media system, must carry out security control to P2P information through the technology such as identity identifying and authenticating, mandate, data integrity, confidentiality and non-repudiation of security fields.To the control of property right, present stage can be adopted the control of DRM technology; For can being installed based on the P2P Streaming Media broadcast system of enterprise-level, fire compartment wall stops disabled user's visit; P2P stream media system on the internet can guarantee safety through the packet cipher mode.In the P2P stream media system, can adopt the grading authorized way of user, stop unauthorized access.
3.p2p the problem of Streaming Media transmission
Server comprises child node peer server and father node server in the P2P Streaming Media.What each server section adopted is the service mode of one-to-many, needs a large amount of child node peer data download request of concurrent processing, and the imbody of service is exactly that media stream data externally is provided; Very tight with the relation of local bandwidth; And when handling request, must consider the self-ability problem (mainly referring to upload bandwidth) of server, the self-ability of each peer server; When initial, all be unknown; The speed of department server divisional processing peer request has influenced the efficiency of service of server to a great extent.If the request of processing speed is slow, efficiency of service certainly will be lower; If that handles is fast, the corresponding accuracy of result will reduce.Under the self-ability condition of unknown, respond the request of data of each peer accurately, just become the key issue of the efficient service of server.Have only the sufficient own resources that utilized, realized the shared maximization of network data, and responded the peer request fast and accurately, just realized the high efficiency service.More difficult to manage here is exactly the detection problem of the upstream bandwidth of peer server.Common way is, at first accomplishes the detection of bandwidth, promptly goes to some addresses to download (uploading/downloads) a part of data, through the data volume and download (uploading/download) the consumption time computation bandwidth of download (uploading/download).As everyone knows; The stability of the network bandwidth is that everybody can't guarantee; The accuracy of so at first this way is exactly suspectable; Also existing problems on the ratio of next upstream bandwidth and downlink bandwidth, and start and just to go to download (uploading/download) so piece of data, bandwidth consumption also is bigger.Be directed to the peer end of p2p technology, bandwidth originally is just very limited, carries out this consumption that has little significance again, and the efficient of initial start stage should be poor.
4. notion gathers
Server, as shown in Figure 1, comprise child node peer server and father node server, promptly the two is referred to as server.
Streaming Media is meant the media formats of the mode of employing stream transmission in the Internet/Intranet broadcast, like audio frequency, video or multimedia file.
Receive data terminal, a certain node (peer) receives the data that other servers provide, and this node (peer) is called the reception data terminal.
Send data terminal, a certain server provides data for other peer nodes, and this server is called the transmission data terminal.Send data terminal among this paper and both comprised the node that is sending data, comprise that also relative reception data terminal can send the node of data.
Summary of the invention
Under the resource condition of unknown of server own, should make full use of this part unknown resources, make response again fast and accurately, this situation is optimal mode.But this also possibly accomplish hardly.For this reason, the objective of the invention is as far as possible to this desirable mode near.Abandon the step of at first accomplishing bandwidth detection in the prior art, but under bandwidth unknown condition, be that node provides data with maximum, the most direct mode, and confirm the state of bandwidth and the action of taking according to the speed of download of reality.Thereby it is the fastest to reach real-time response, and data transmission efficiency is the highest.
In order to achieve the above object; The present invention is a kind of to realize the method for P2P stream media system based on bandwidth guarantee technology, comprises the steps: a step that receives that data terminal confirms whether a plurality of transmission data terminals have its required file and send download request to the transmission data terminal with its required file; Sending data terminal is the step of the download request setting priority of a plurality of reception data terminals with time sequencing.Situation a is under the prerequisite of the data providing capability the unknown of sending data terminal, and the present invention comprises the steps: that also (a1) this transmission data terminal directly provides data for a reception data terminal of high priority; (a2) this transmission data terminal is V at the actual average transmission speed that 2-5 detects in second to this reception data terminal 1(a3) establish this transmission data terminal and guarantee that the required speed of download of this reception data terminal normal play files in stream media is T; When detecting V<T for continuous 2-4 time; This transmission data terminal is confirmed to have reached the maximum data providing capability and known this ability, and temporarily for the reception data terminal of this reception data terminal and littler priority data is not provided; When the situation of V<T is not detected by continuous 2-4 time; Then continue the transfer of data of this transmission data terminal and this reception data terminal; And should send data terminal is the reception data terminal transmission data of next priority; Step after the repetition (a2) is until confirming that this transmission data terminal has reached the maximum data providing capability and known this ability.
The present invention is based on the method for bandwidth guarantee technology realization P2P stream media system; Send under the prerequisite that the data providing capability of data terminal knows at situation b; Also comprise as follows step by step: (b1) this transmission data terminal is directly downloaded for the high reception data terminal of priority provides data, until reaching the maximum data providing capability; (b2) this transmission data terminal has reached the maximum data providing capability, then should send the download request of data terminal for the low reception data terminal of other priority, and data wouldn't be provided.
Wherein, The situation of above-mentioned steps (b1) mostly occurs when sending data terminal and receiving the transfer of data disconnection of data terminal; At this moment; Know owing to send the data providing capability of data terminal, therefore directly download, get final product until reaching the maximum data providing capability for the high reception data terminal of priority provides data.And the situation that transfer of data is broken off comprises that required file download finishing disconnection connects or data transmission fault breaks off connection.
In addition, the present invention is based on the method that the bandwidth guarantee technology realizes the P2P stream media system, it further improves and is, also comprises step: each receives data terminal and detects the actual download speed V from a certain transmission data terminal in second at 3-6 2, when The time, this receives data terminal meeting active disconnection and sends being connected of data terminal, looks for data source again.
The present invention is based on the bandwidth guarantee technology and realize that the method for P2P stream media system mainly realizes that through following three phases data are sent and reception.
A, ability value is unknown: when initial, the self-ability value is 0 certainly; This moment, we can think that the ability of this node (peer) or server is very big, during processes data requests, all adopted sure answer mode, and the detecting self ability value.The purpose of this moment is exactly to reach maximum capacity own in the data of asking before the high efficiency service can be provided externally.
B, ability value is unknown: constantly accepting request, sending in the process of data, the data volume of transmission has been closed on self maximum capacity, and the part of surveying can not detect and reached maximum capacity, also can continue to accept request, and data externally are provided.Will take place this time; The ability of self can not satisfy the data conditions of external request; And peer that causes asking afterwards and first peer contention bandwidth; Reach the standard grade in a large number and roll off the production line if very serious peer will take place the bandwidth that tied up peer first, make whole unstable networks.We way herein are to send data according to prioritization and (according to the order of accepting the request of child node peer data download, distribute priority from high to low; When data are provided; Being preferably the high child node peer of priority provides), ensure peer before reaching the maximum capacity value with this with regard to having begun to download, can normally send data; Can not receive the influence of peer finally, the situation of unstable networks more can not occur.The purpose of this moment is exactly in the peaked decline of detectivity, avoids bandwidth contention situation, ensures the stable transfer of peer data, ensures stability of network, and can the high efficiency service.
C, ability value is known: when the generation self-ability can not satisfy all request of data, just can confirm to have reached maximum capacity, through the mode of data statistics, calculate the maximum capacity value.This moment is just relatively simple, only need simply calculate just can make accurately to have responded; The purpose of this moment is in the known situation of ability value, to respond the peer request fast and accurately, the service of realization high efficiency.
The present invention is based on the method for bandwidth guarantee technology realization P2P stream media system; Characteristics to the P2P technology are constantly externally providing in the service process, and surveymeter is calculated the maximum capacity value of itself; Do not have the insignificant consumption of bandwidth, stability also guarantees to some extent.Specifically, the present invention has following beneficial effect:
1, child node peer data download velocity-stabilization is for the Streaming Media stable playback of peer provides strong guarantee.
2, can control the behavior of rolling off the production line of frequently reaching the standard grade of child node peer, the influence to other child nodes peer of association is caused is controlled at influence within the very little scope, can not impact whole data sharing network.
3, self accomplish the maximum capacity value and calculate, saved the resource of outside detection, and more accurate, be of value to band-limited maximum using.
4, server is answered the data download request of child node peer fast and accurately, has significantly shortened the time of peer searching consumer of data, has improved efficiency of service.

Embodiment
The present invention at first satisfies the condition of " quick and precisely handling request ", secondly is the treatment effeciency that guarantees in the detection process of maximum capacity value, is exactly that the influence that the maximum capacity value is surveyed is reduced to minimum once more.Processing after the maximum capacity value survey to be accomplished is just fairly simple, will more than several promises good, just can bring into play the maximum capacity of client basically, under the self-ability condition, the high efficiency service that provides is provided.
Realize the above object, need three parts to coordinate to accomplish:
A, server end are accepted in the process of child node peer data download request, accomplish self-ability and survey.
The priority that b, server end distribute when accepting " request of child node peer data download " is that peer sends data.
C, peer client downloads speed detect.
Ginseng specifically describes the entire process process according to embodiment below:
Identical with prior art P2P stream media system and other P2P software, which the reception data terminal of waiting to receive data need confirm is sent data terminal and has its required file, and sends data terminals to these and send download request.The a certain files in stream media that wherein alleged " required file " is meant broadcast among the present invention is through splitting a plurality of small documents that form.Concrete fractionation mode can be joined the Chinese invention patent of applying on the same day according to the applicant and the present invention " a kind of method based on data disassemble technique realization P2P stream media system ".Certainly the present invention is not limited to file and splits, but is conceived to split the transmission of back file, so the present invention is applicable to that various P2P stream media systems need the situation of file transfer (no matter which kind of fractionation mode, even do not split file).
When a plurality of reception data terminals when same transmission data terminal request msg is downloaded, this sends data terminal and receives the download request setting priority of data terminals with the sequencing of time for these; Time, more early priority was high more.Flow process as shown in Figure 3 is following:
1, program initialization; It is unknown state (this ability is called the maximum data providing capability) certainly that a peer server perhaps send data terminal to provide the ability of service; Add a peer download request (the reception data terminal request of high priority) this moment; Send data terminal and can't guarantee to satisfy the other side's downloading request, but must make response immediately and data are provided.
Countermeasure: courageously hypothesis, and detection maximum capacity value.Suppose oneself can satisfy the other side's downloading request, directly download the peer affirmative answer.The meaning in other words, the data that I can provide you to require to you, you at me down.Because the ability that data are provided of itself is not clear, can not guarantee speed, send the data speed detection so need download peer this moment to this.With the fixed time is the standard detection time, and the time specified in 2 to 5 seconds, counts the total amount of the data of sending in the standard time, obtains the in fact data volume of transmission each second, is called the actual average transmission speed.Can confirm according to the state of peer for the speed of the transmission data of each peer, be referred to as normal transmission speed, promptly should send data terminal and guarantee that this receives the required speed of download of data terminal normal play files in stream media.
If the actual average transmission speed, obtains testing result " normally " more than or equal to normal transmission speed, and continue transfer of data.At this moment; This transmission data terminal is with ability " counting adds "; And be set to and send data for the reception data terminal of next priority; Thereby the download of adding next priority according to the priority of request connects, and peer of every interpolation need detect, till detecting the maximum capacity value.Wherein, This transmission data terminal its objective is ability " counting adds ", sends data terminal through counting mode and counts at following maximum number that can connect of download capabilities performance maximum rating; Thereby for follow-up phase (as breaking off the process of connection/data reconstruction passage/transmission data) provides reference; Utilize this maximum number, do and subtract one-plus-one counting, can determine the transmission state of some passage as reference.
If the little and normal transmission speed of actual transmission speed obtains testing result " slowly "; Need carry out number of times accumulative total in the time of " slowly ".And the examination criteria of arrival maximum capacity value is that the child node peer that continuous detecting goes out for specify number (number is specified) in 2 to 4 provides data speed " slowly ".Noting, is continuously several, and the reason of so doing is, if middle occurred downloading slow, and back can normal downloading, this situation has nothing to do with the providing capability of self, belongs to network problem, or the other side's problem.If be consecutively detected several slowly, explain that the current service ability that provides has reached maximum, and override capability scope.Confirm that the maximum capacity value produces this moment, and begin to calculate concrete data, confirm the maximum capacity value through the total amount of the transmission data in statistics a period of time.And usually, receiving data terminal this moment can connect in the active disconnection.
2, when surveying the maximum capacity value, when only providing data volume to exceed providing capability own, can detect the maximum capacity value.How should data outside the override capability solve so? For example itself can provide the data of 1M a second; And the data of need sending be one second 1.2M; This moment, whom the data of that 1M should send on earth, and how remaining 0.2M data should be handled has just become the key here.The way of taking is: under the situation that reaches the maximum providing capability of data, send data terminal and temporarily for the reception data terminal of low priority data are not provided.Concrete countermeasure is following:
In order to ensure stability of network, carry out with the principle of " peer does not afterwards influence peer first "; According to the time sequencing of request, give the peer corresponding priorities that each comes request msg here, the priority afterwards of priority ratio first is high.When sending data to peer, directly data are not sent in the network, but send in the priority query, priority query can arrange according to the priority of peer under the data.The meeting that the priority of peer is the highest comes the top of whole formation, at first is sent out.Each downloads peer all has a thread to travel to and fro between between priority query and the network, sends data, and each thread all only can send the data that come the top of priority query.As shown in Figure 2 have six peer just in data download, and the transmission speed of each peer is the 0.2M per second, be total to the 1.2M per second, but the transmitting capacity of bottom remote peer (transmission data terminal) has only the 1M per second, and this moment, the height of priority was just most important.Sort according to sequence number; It is the highest to download peer1 priority; It is minimum to download peer6 priority, and each peer sends data in priority query, will find that so the data of peer1-5 can both normally send this moment; The data of peer6 but exist in the priority query always, can not send.Send not meet when data and send when requiring; Each all peer all can produce second group of data and be placed on and carry out " occupy-place " behavior in the priority query; Send thread and only understand the highest data of transmit queue medium priority; So just guaranteed that the data of the peer that priority is high send stability, avoided being influenced by afterwards peer.
3, through top processing, can find to have at last a download peer can't obtain data, can exert an influence to this peer so equally.To this, server section (transmission data terminal) is powerless, but can not let go unchecked.
Countermeasure: each downloads peer (reception data terminal) originally after obtaining affirmative answer; The capital receives data speed and detects, with the set time (time is selected in second at 3-6) be one detection period, begin from the time that receives a reply; How many data have been received altogether in the statistics set time; If be lower than the half the of normal downloading speed, directly being connected of disconnection and server, seek data source in addition.Arrive here, the state of server just should be maximum performance, has just reached self efficient resource that makes full use of of saying above us basically, and the state of efficient service is provided.
Above-mentioned normal downloading speed is identical with normal transmission speed; For example concrete: as suppose that 30 transmission data terminals (server) are one and receive the video file that data terminal peer provides per second 30 frames, and each to send the data that data terminal correspondence provides video file different frame each second.At this moment; Each sends data terminal as long as guarantee the speed sending data of 1 frame/second; And the reception data terminal guarantees that the speed of 1 frame/second receives each data in server; Can guarantee to receive the data terminal video file normal play of 30 frame/seconds, be exactly normal downloading speed or normal transmission speed this 1 frame/second of this moment.
4, come this moment the peer request to download again, should how to handle;
Countermeasure: the maximum capacity that can confirm to provide the ability of data to reach self this moment, but the concrete numerical value of maximum capacity does not also calculate.Next in a period of time of calculating maximum capacity, can not accept any child node peer data download request.But not serious because used in the current time by maximum in ability in fact, can not be again for other child node peer provides data to download, can think does not temporarily have ability that data externally are provided again.Can give negative reply this moment, tells the other side that I can not offer you.That is to say that at this moment, this sends data terminal for the low reception data terminal download request of other priority, and data wouldn't be provided, refusal is downloaded; Detect the half of actual download speed less than normal speed and receive data terminal in second at 3-6, this receives data terminal meeting active disconnection and sends being connected of data terminal, looks for data source again.
In addition, concrete maximum capacity value (" maximum number of connections ") is calculated after the completion; Also to directly add up once current transmission data summation; Speed of download through all being downloaded peer adds up, and obtains the current speed summation that data externally are provided, and is called " current linking number ".Each peer of download adds, and deletion all will be upgraded once current linking number.When receiving request again, just can directly compare, data just are provided, less than data just are not provided greater than speed of download with the difference of maximum number of connections and current linking number and the speed of download of request.For example download and finish or during data transmission fault at required file; A certain connection is broken off; This moment is owing to the data providing capability of sending data terminal knows; Sending data terminal is that the high reception data terminal of priority provides data to download with the maximum data providing capability directly, gets final product until reaching the maximum data providing capability.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
