Peer-to-peer computer network (Peer to Peer, P2P) system is made of numerous P2P nodes, and each node can Resource can also be published on Resource Server after downloading complete resource by P2P network download resource, saved to other Point provides upload service.

In P2P network system, since network data abduction is distorted, small operator is redirected, and the bad card of disk leads to local The various problems such as data corruption, cause to will appear wrong data in data transmission procedure.If there is error number in video resource According to, will lead to user and occur Caton during playing video, various broadcasting such as flower screen extremely, strong influence user's body It tests.

In addition, P2P network is a divergence form network, once the wrong data of P2P node, it will be in a short time Rapidly throughout whole network, entire P2P network system is caused to be paralysed.

In order to guarantee that the correctness of resource data, general solution are after resource downloading completion, to entire text Part does a MD5 verification, judges whether there is wrong data, detailed process is as follows for scheme:

Before starting to download resource, the MD5 value A of the resource is first requested to Resource Server, after downloading completes, to whole A resource file calculates a MD5 value B.Judge whether A and B is equal, if unequal, illustrates that current file and original document have Difference, there may be wrong data for the inside.Resource can neither be supplied to player use in this case, it can not be by resource Other nodes are uploaded to, need to delete entire resource at this time, then re-download.If check results are that two MD5 values are consistent, say Bright the inside does not have wrong data, and this document can be used normally.

But existing solution, entire resource is needed all to delete after there is wrong data.This For big resource file (such as: video, generally for several MB to several GB etc.), because the wrong data of part, causes The deletion of entire file, then re-download, it will result in the huge wasting of resources.

In addition, existing solution can not solve the case where local data is destroyed.For example, after downloading completes, Passed through using MD5 verification, but file data is destroyed during being locally stored, when uploading resource, directly to right Side provides data, still can introduce wrong data to network.

Specific embodiment

Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure It is fully disclosed to those skilled in the art.

The scheme of traditional resource sharing, mainly using complete resource file as the resource object shared, in P2P net Resource downloading or resource publication are carried out in network.As shown in Figure 1, being the logical architecture figure of traditional resource sharing scheme.Such as Fig. 1 Shown, the main body in traditional P2P network mainly includes server 110, CDN (content distributing network) 120 and P2P node 130, Wherein:

Server 110, for storing the resource information that each P2P node 130 is issued in P2P network, it should be noted that only The resource information can just be issued to server by having the P2P node for the complete content for possessing a certain resource；The resource being published It include: the resource ID for being published resource, resource size information, MD5 value and the resource node information structure for issuing the resource in information At resource node list；

CDN120, the networked storage units of the complete content for storing a certain resource, uniquely being specified by resource URL should The storage location of CDN120；

P2P node can be illustrated as logging in the terminal device (can be multiple) in P2P network, each P2P from the angle of broad sense Resource sharing can be carried out between node, wherein request the P2P node of resource downloading to can be described as requesting node, downloading resource is provided P2P node can be described as resource node, to server 110 issue resource information P2P node can be described as publisher node, each P2P node can switch role according to behavior during resource sharing.Each P2P node may include two parts, client App and accelerator, client App is mainly used for responding the resource playing request of user, and is downloaded from P2P network by accelerator Requested resource in playing request, therefore a P2P can be illustrated as from the accelerator in the angle of narrow sense, each terminal device Node.

Specifically, when requesting node is intended to download a certain resource, can first in local according to unified resource ID create-rule, And the resource URL of requested resource generates the corresponding resource ID of the resource (the corresponding unique resource ID of each resource). Then the resource ID is sent to server 110, whether to store the information of the resource comprising the resource ID on query service device； If it is not, downloading the resource from CDN120 (if requesting node thinks that publication should according to the resource URL of requested resource Resource need to download complete resource from CDN120), if so, then obtaining the corresponding resource information of requested resource；From acquisition Resource information in take issue the resource resource node, and to the resource node send resource download request, the request In include resource ID and resource MD5 value, to download the resource from resource node.

After resource node receives the resource download request of requesting node, found from local information bank according to resource ID Corresponding resource information entry, and the MD5 value carried in the MD5 value of resource therein and request is compared, if identical Requested resource is then extracted from local storage unit, verification then is carried out to resource, check value is calculated, and again will The MD5 value of resource is compared to realize and verify to the integrality of the resource with the check value, if two values are identical, Determination verifies successfully and sends resource to requesting node.

After the completion of requesting node downloads a certain resource, for the integrality of Support Resource, master gage can be carried out to resource Calculation obtains check value, and is compared to the MD5 value of resource and the check value to realize the integrality progress to the resource again Verification, if two values are identical, it is determined that verify successfully, and retain the resource to local storage unit.

It, can be first right when requesting node changing role is intended to issue the information of the resource to server 110 as publisher node Resource carries out verification and check value is calculated, and is compared to realize to the money by the MD5 value of resource and the check value again The integrality in source is verified, if two values are identical, it is determined that is verified successfully and is disappeared to the transmission resource publication of server 110 Breath, completes the publication of resource；If verification failure does not send resource to server 110 for Current resource and gives out information.

It can be learned from Fig. 1, share the behavior of resource between each P2P node 130, P2P node 130 is obtained from server 110 The behavior of the resource information taken is premised on the resource of publisher node publication is complete resource.It is downloaded in requesting node Resource requires the MD5 value pair using resource during resource node provides resource and publisher node publication resource information Corresponding resource carries out completeness check, to guarantee the integrality for the resource propagated in P2P network.But requesting node Complete resource is downloaded from resource node, the especially biggish full resource of file is highly difficult, and reason is to download node The resource requested every time may not be inherently complete resource, or in downloading and during storage resource it is possible that Wrong data, and these situations may cause resource and not passed through when carrying out completeness check, and once verify and do not pass through, Requesting node can not just judge the correctness of resource data, even if there are mistakes for the data content of only small part, also will Entire resource is deleted, and from newly downloaded, to reduce resource, the P2P of especially big file resource shares efficiency.

Logical architecture of this programme based on the sharing scheme in traditional P2P network introduces new to resource file Checkschema.As shown in Fig. 2, the logical architecture based on the sharing scheme in traditional P2P network, in the present solution, being saved in each P2P Unified resource segmentation rules are increased in point, so as to the piecemeal resource after same resource file cutting on each P2P node Content is identical.Meanwhile the checking algorithm of built-in identical piecemeal resource, guarantee that the corresponding check value of identical piecemeal resource is identical, To guarantee that the corresponding piecemeal check information of same resource is identical.After so-called piecemeal check information is carries out cutting to resource, Each piecemeal resource of formation is carried out that check value is calculated respectively by default checking algorithm, and will be after the splicing of these check values It is formed by character string.

This programme is when verifying resource file, by the way of piecemeal resource checksum.Resource node is providing money During source, during downloading resource, only piecemeal resource checksum to be shared passes through requesting node, so that it may share or Store corresponding sub-block resource.But there is still a need for when issuing message related to resources to server 110 with publisher node local for publisher node It is stored with premised on complete resource.It include resource ID, piecemeal check information (or piecemeal in the resource information of publisher node publication The MD5 value of check information, piecemeal check information is stored on resource node at this time, and requesting node need to pass through the piecemeal check information MD5 value obtain piecemeal check information from resource node), resource node list and other resource informations such as: resource size, MD5 value of resource etc..

This programme can be related to following side when verifying to resource file by the way of piecemeal resource checksum The problem of face: the problem of resource that the acquisition problem of piecemeal check information, resource node treat sharing is verified, requesting node The problem of the problem of resource downloaded is verified, publisher node publication resource information.

Firstly, the acquisition problem of piecemeal check information, refers to how requesting node gets the piecemeal school of resources to be downloaded Testing information, (resource node has locally been stored with the piecemeal check information of resource when issuing resource information, therefore this problem relates to And main body is requesting node) the problem of.

In the present solution, requesting node can go to obtain the piecemeal check information of resources to be downloaded by two kinds of approach, it is a kind of It is to be obtained from server, one is obtain from the resource node for providing resource.It is obtained from server, needs resource node When issuing resource information, the piecemeal check information of resource is sent to server and is saved.From the resource node that resource is provided It obtains, needs resource node when issuing resource information, the corresponding check value of piecemeal check information of resource is sent to service Device saves, so that resource node can get piecemeal check information by the check value from resource node.

Secondly, the problem of resource that resource node treats sharing is verified, refer to how resource node asks to being supplied to The problem of asking the resource part of node to be verified.

In the present solution, the full resource file that resource node by unified resource segmentation rules, can treat sharing carries out Cutting forms multiple piecemeal resources, then by requesting node request resource part be mapped in these piecemeal resources, and to The resource part of request has the piecemeal resource of coincidence to be verified using piecemeal check information.If verification passes through, to request Node sends corresponding resource.

Again, the problem of requesting node verifies the resource downloaded refers to requesting node how to from resource section The problem of resource part downloaded at point is verified.

In the present solution, requesting node can carry out full resource file to be downloaded by unified resource segmentation rules Cutting forms multiple piecemeal resources, then by actual request download resource part be mapped in these piecemeal resources, and to Piecemeal resource has the resource part of the request of coincidence to be verified using piecemeal check information.If verification passes through, phase is saved The resource answered is to local.

Finally, publisher node issues the problem of resource information, refer to that downloading node is downloaded to from resource node or from CDN After complete resource file, if the resource information of these resources is published on server.

In the present solution, publisher node can cut local full resource file by unified resource segmentation rules Divide and form multiple piecemeal resources, the check value of each piecemeal resource is then calculated separately using preset checking algorithm, then by this A little check value splicings, form the piecemeal check information of resource.Publisher node, can be by piecemeal when issuing resource information to server Check information is directly published on server, can directly be obtained from server side so as to call request and download the requesting node of the resource Get the piecemeal check information；Verification can also be carried out to piecemeal check information, check value is calculated, then send out the check value On cloth to server, it can be got by the check value from resource node side so as to call request and download the requesting node of the resource The piecemeal check information.

The technical solution of the application is further illustrated below by multiple embodiments.

Embodiment one

Based on the logical thought of resource sharing scheme shown in Fig. 2, as shown in figure 3, it is shown in the embodiment of the present invention The acquisition methods flow chart one of resource checksum information, the main request section in P2P node shown in Fig. 2 of the execution of this method Point.As shown in figure 3, the acquisition methods of the resource checksum information include the following steps:

S310 sends resource information request to server, to obtain the resource information of resources to be downloaded；

For example, when user's one video file (resources to be downloaded) of click play on client App, client App can be to Accelerator sends the playing request of file, and the form of playing request can be hypertext transfer protocol (Hyper Text Transfer Protocol, HTTP) request, such as http: // 127.0.0.1:7878/www.youku.com/xxxxxx.flv.HTTP's In header, fooled corresponding block information in requested resource part of meeting band, such as [15MB, 25MB), that is, it requests requested Data in resource between 15MB to 25MB.

Above-mentioned HTTP request is to be used to download existence anduniquess in the resource URL, each resource URL of requested resource The critical field information an of resource is identified, such as " xxxxxx.flv " in above-mentioned resource URL.Requesting node is being connected to client App send for downloading the resource URL of requested resource after, extracted from resource URL it includes critical field information.

Accelerator is to the keyword extracted from the resource URL parsed in the HTPP request that client App is sent Segment information does MD5 operation, generates a MD5 value.On the basis of MD5 value, some auxiliary informations are added, such as resources to be downloaded Description information (this refers to type, the media content names of the particular content of resource, such as media content), and provide under The customer information of resource is carried (if provide resource is youku.com, then can be using youku.com's title or specified character string identification as visitor Family information) spliced, ultimately form a resource ID such as the character string with 40 bytes as resources to be downloaded, form It can be as follows:

20010211AAAAAAAAAAAAAAAAAAAAAAAAAAAA。

The request of the resource information of resource ID comprising above-mentioned resources to be downloaded is sent to server by requesting node, with from clothes Business device obtains the resource information of resources to be downloaded, and the resource information obtained here is primarily referred to as the piecemeal verification letter of resources to be downloaded The resource node information of breath and offer resources to be downloaded.

S320 receives the resource information that server returns, which includes: the piecemeal check information of resources to be downloaded And resource node information；

Wherein, piecemeal check information is after carrying out cutting to resources to be downloaded, to press respectively to each piecemeal resource of formation Default checking algorithm carries out that check value is calculated, and will be formed by character string after the splicing of these check values；Piecemeal verification letter Breath is that server searches acquisition according to resource ID in local information library, each piecemeal resource for being included to resources to be downloaded It is verified；The position of node where resource node information indicates resources to be downloaded, such as resources to be downloaded can be to provide Resource node IP address list.

Wherein, it is identical, such as right for carrying out segmentation rules used by cutting to same resource file on each P2P node Video resource can carry out resource cutting according to dimensions such as play time, data flow length when carrying out cutting, to be formed multiple Piecemeal resource.What needs to be explained here is that the resource being split must be complete resource file, complete resource is cut Divide the size for being formed by each piecemeal resource may be the same or different, but is advised for same resource file using the cutting When then carrying out cutting, the size of each piecemeal resource formed every time is corresponding identical.

For example, when carrying out cutting using fixed-length data stream mode, the length of each piecemeal resource be it is identical, walked with cutting For a length of 10MB, then carrying out the length of each piecemeal resource that cutting obtains to some resource file is 10MB, and each point The corresponding length of interval of block resource be respectively [0MB, 10MB], (10MB, 20MB], (20MB, 30MB] ... ....

Publisher node is published the resource of resource may include into the resource information for the full resource that server is issued ID, piecemeal check information and resource node information (public network address of such as resource node, the public network port of node, node The address Relay, the port Relay of node, address of node type etc.).Therefore, requesting node can be got from server side to Download the piecemeal check information of resource.

Certainly, if the resources to be downloaded of requesting node current request are not published on the server, server is returned Resource information back to resource node is sky.At this point, requesting node can be according to the resource URL of resources to be downloaded from providing resource CDN downloads respective resources content.

Further, it may also include the whole check information of resources to be downloaded in above-mentioned resource information, for to be downloaded Resource carries out whole verification.

Whole verification is carried out for the ease of resource of the requesting node to downloading or requesting node requests to provide to resource node When source, resource node checks requesting node requested resource, in resource node as publisher node publication resource letter When breath, the whole check information for the resource currently issued is also added in the resource information of publication, which uses In the whole verification of resource progress to publication.

The acquisition methods of the resource checksum information of the embodiment of the present invention, requesting node is by sending resource information to server Request, to obtain the piecemeal check information of resources to be downloaded, and then using the piecemeal check information to locally downloading later Resource is verified respectively by each piecemeal resource, to improve the sharing rate of resource.

Embodiment two

Based on the logical thought of resource sharing scheme shown in Fig. 2, as shown in figure 4, it is shown in the embodiment of the present invention The acquisition methods flowchart 2 of resource checksum information, the main request section in P2P node shown in Fig. 2 of the execution of this method Point.As shown in figure 4, the acquisition methods of the resource checksum information include the following steps:

S410 sends resource information request to server, obtains the resource information of resources to be downloaded, the resource information packet It includes: the first check value and resource node information of piecemeal check information；Piecemeal check information is used for the multiple of resources to be downloaded Piecemeal resource is verified；For first check value for verifying to piecemeal check information, resource node information instruction is to be downloaded It may also include the resource ID of resources to be downloaded where resource in the location resource information request of node；

Wherein, the generating process of the resource ID of resources to be downloaded can be found in the corresponding contents in step S310.

The request of the resource information of resource ID comprising above-mentioned resources to be downloaded is sent to server by requesting node, with from clothes Business device obtains the resource information of resources to be downloaded, and the resource information obtained here is primarily referred to as the piecemeal verification letter of resources to be downloaded First check value of breath and the resource node information of offer resources to be downloaded.

Received server return resource information in include: resources to be downloaded piecemeal check information first verification The resource node information of value and offer resources to be downloaded；

Wherein, piecemeal check information is after carrying out cutting to resources to be downloaded, to press respectively to each piecemeal resource of formation Default checking algorithm carries out that check value is calculated, and will be formed by character string after the splicing of these check values；First check value For the check value that character string is calculated by default checking algorithm, first check value can for server according to resource ID at this It searches and obtains in ground information bank, each piecemeal resource that piecemeal check information is used to be included to resources to be downloaded verifies.

Wherein, cutting is carried out to a full resource to be formed used by process and the dicing process of multiple piecemeal resources Segmentation rules are detailed in the corresponding contents in step S320.

Publisher node is published the resource of resource may include into the resource information for the full resource that server is issued Information (public network address of such as resource node, the section of ID, the first check value (such as MD5 value) of piecemeal check information and resource node The public network port of point, the address Relay of node, the port Relay of node, address of node type etc.).Therefore, requesting node The first check value of the piecemeal check information of resources to be downloaded can be got from server side.

S420 sends the request of piecemeal check information to resource node, obtains resources to be downloaded according to resource node information Piecemeal check information, the piecemeal check information request in include: the first check value；

Requesting node extracts resource node information from receiving in the resource information sent by server, and to money Source node initiates the connection request, establishes network connection.Requesting node sends piecemeal verification letter to the resource node that connection has been established Breath is requested, the first check value obtained from server before including in the request, can also include the resource of resources to be downloaded ID。

Later, requesting node can receive the piecemeal check information of the resources to be downloaded of resource node return, the piecemeal school Testing information can search in local information library for resource node according to resource ID, and send out after being verified using the first check value Out.

After resource node receives the piecemeal check information request of requesting node transmission, respective resources pair can be found from local Second check value of the piecemeal check information answered, and second check value is compared with above-mentioned first check value, if the One check value is identical as the second check value, then shows the piecemeal resource checksum information that resource node is locally stored for resource node institute The piecemeal check information of request.At this point, the piecemeal check information being locally stored can be sent to requesting node by resource node.

Wherein, the second check value is after resource node carries out cutting to the full resource being locally stored, to each of formation Piecemeal resource is carried out that check value is calculated respectively by above-mentioned default checking algorithm, and will be formed by after the splicing of these check values Character string.

Specifically, resource node is searched in local information library, and using the first check value verifying piecemeal check information Step specifically may include following content:

Resource node can search whether there is the resource comprising the resource ID according to resource ID in local resource information library Data entries may include resource ID, the piecemeal check information of the announced resource of resource node in each resource information entry The store path of second check value and piecemeal check information；

If there is the resource information entry comprising resource ID, then resource node is by the first check value and the resource information item The second check value is compared in mesh, if identical, it is determined that issues the piecemeal check information under store path.

For example, resource node from the piecemeal check information request that requesting node is sent, parses resource ID, piecemeal verification After first check value of information, searched whether from local information bank in the presence of the resource information entry for including the resource ID. Wherein, resource node, can be using the resource information of publication as resource when issuing resource information value server as publisher node Data entries are stored in local information bank, i.e., a plurality of similar this resource letter is stored in the local information library of resource node Cease entry.The second verification of the resource ID, piecemeal check information of announced resource is contained in every resource information entry The store path of value and piecemeal check information.

If resource node does not find the resource information comprising the resource ID from local information bank according to resource ID Entry then returns to the local feedback information that institute's request content is not present to requesting node.

If resource node finds the resource information item comprising the resource ID from local information bank according to resource ID Mesh, then resource node further extracts the second check value in the resource information entry, then by above-mentioned piecemeal check information The first check value in request is compared with second check value, if two values are identical, according in the resource information entry The store path of the piecemeal check information of record reads out corresponding piecemeal check information and is sent to requesting node；If two Value is not identical, then returns to the local feedback information that institute's request content is not present to requesting node.

After requesting node receives the piecemeal check information of the resources to be downloaded of resource node return, so that it may under subsequent It is downloaded to the verification that local resource carries out piecemeal resource.

It further, further include the whole check information of resources to be downloaded in above-mentioned resource information, for money to be downloaded Source carries out whole verification.

Whole verification is carried out for the ease of resource of the requesting node to downloading or requesting node requests to provide to resource node When source, resource node checks requesting node requested resource, in resource node as publisher node publication resource letter When breath, also add the whole check information for the resource currently issued in the resource information of publication, the check information for pair The resource of publication carries out whole verification.

The acquisition methods of the resource checksum information of the embodiment of the present invention, requesting node first send resource information to server and ask Ask, to obtain the first check value of the piecemeal check information of resources to be downloaded, then, using first check value to provide resource Resource node send the request of piecemeal check information, to get resources to be downloaded corresponding piecemeal verification letter from resource node Breath, and then resource locally downloading later is verified respectively by each piecemeal resource using the piecemeal check information, to mention The sharing rate of high resource.

Based on the logical thought of resource sharing scheme shown in Fig. 2, as shown in figure 5, it is shown in the embodiment of the present invention The method of calibration flow chart one of piecemeal resource, the main resource node in P2P node shown in Fig. 2 of the execution of this method.Such as Shown in Fig. 5, the method for calibration of the piecemeal resource includes the following steps:

S510, receives the resource download request that requesting node is sent, and includes the of resources to be downloaded in resource download request One block information；

Wherein, first interval information is part resource in the resources to be downloaded requested every time of requesting node entirely under Carry the corresponding range information of resource.

Requesting node can be by whole resources of request point in multiple P2P tasks, then to resource as unit of P2P task The request of resource is downloaded in node starting, contains the resource ID for the resources to be downloaded that this subtask is downloaded in each P2P task, First interval information corresponding with the resource part that this needs is downloaded.If client APP is being sent to the HTTP of accelerator In header, fooled corresponding block information in requested resource part of meeting band, such as [15MB, 25MB), that is, it requests requested Data in resource between 15MB to 25MB.Accelerator can to block information [15MB, 25MB) corresponding resource downloading appoints Business is further decomposed, and is generated multiple P2P tasks, and form a P2P task pool, is stored in local memory.Each P2P The content information of task can include: the resource ID of resources to be downloaded, the initial position of data block of this request, data block it is big It is small etc..

Accelerator successively extracts a P2P task from task pool, and is sent and provided to resource node according to task definition Source downloading is requested, and includes the resource ID and first interval information of resources to be downloaded in the resource download request.Wherein firstth area Between information be the initial position of data block for corresponding to this request, the size of data block.For example, the data block of current request Initial position be 8KB, data block size be 9KB, then corresponding first interval be [8KB, 17KB).

S520, each piecemeal for being included with the resources to be downloaded found in local storage unit by first interval information The corresponding interval range of resource is compared, determining to have the first piecemeal resource for being overlapped section with first interval information；

For example, being 8KB, data when the first interval information in the received resource download request of resource node is initial position Block size is 9KB, then corresponding first interval be [8KB, 17KB).If forming the corresponding segmentation rules of piecemeal resource is to complete After resource file sequence cutting, each piecemeal resource size is 10KB, then this requested data block, fall in [0KB, 10KB) [10KB, 20KB) in two piecemeal resources.Wherein, [0KB, 10KB), [10KB, 20KB) corresponding to piecemeal resource be One piecemeal resource.

S530 carries out verification calculating using preset checking algorithm to each first piecemeal resource respectively, obtains third verification Value；

For example, to it is above-mentioned [0KB, 10KB), [10KB, 20KB) corresponding resource part using preset checking algorithm (such as MD5 algorithm) it carries out that two third check values (MD5 value) is calculated.

S540, same piecemeal resource in the piecemeal check information stored in each third check value and local information library is corresponding Check value be compared, if identical, the corresponding resource part of first interval information in corresponding piecemeal resource is sent To requesting node；

Wherein, the piecemeal check information is after carrying out cutting to resources to be downloaded, to each piecemeal resource point of formation It does not carry out that check value is calculated by above-mentioned default checking algorithm, and character string will be formed by after the splicing of these check values.

In the corresponding piecemeal check information of announced each resource stored in resource node local information library, comprising should The corresponding check value of the corresponding whole piecemeal resource of resource, and the check value is also using above-mentioned preset checking algorithm to each point What block resource generated after being calculated.

After the corresponding third check value of above-mentioned each first piecemeal resource is calculated, can by these third check values, with The corresponding verification of same piecemeal resource in the corresponding piecemeal check information of the same resource stored in resource node local information library Value is compared, if third check value is identical as the check value size of same piecemeal resource affiliated in piecemeal check information, Show the content intact of the first piecemeal resource, resource node can be corresponding by first interval information in corresponding piecemeal resource at this time Resource part be sent to requesting node.For example, resource node to [0KB, 10KB), [10KB, 20KB) corresponding piecemeal provides After source verifies successfully, can by it is above-mentioned [0KB, 10KB) piecemeal resource in [8KB, 10B), it is above-mentioned [10KB, 20KB) piecemeal In resource [10,17KB) resource part be respectively sent to requesting node.

Further, it may also include money to be downloaded in the resource download request that above-mentioned requesting node is sent to resource node The whole check information in source, the entirety check information are used to carry out resources to be downloaded whole verification；

Corresponding, the above method may also include the steps of:

The whole check information there are resources to be downloaded is searched whether in local resource information library；

It, then will be in the entirety check information and resource download request if there is the whole check information of resources to be downloaded Whole check information is compared, if identical, it is determined that executes the operation of step S520.

Specifically, the resource ID that resource node can based on the received in resource download request, is first looked into from local information library It looks for the presence or absence of the resource information entry comprising the resource ID.It include the announced money of resource node in each resource information entry The resource ID in source and the whole check information of resource.If it is present resource node parses the resource in resource download request Whole check information (check value that such as entire resource is generated by above-mentioned default checking algorithm, such as MD5 value) with find The check information of whole resource in resource information entry is compared, if identical, resource node determines again executes step S520.If comparing resource there is no resource information entry or resource node comprising above-mentioned resource ID in local information library When the complete checks information of the complete checks information of the resource in downloading request and the resource in the resource information entry found, Two values are unequal, then resource node returns to the local message that resource node requested resource is not present to requesting node.

The method of calibration of the piecemeal resource of the embodiment of the present invention, resource node reflect requesting node requested resource data It is mapped in each piecemeal resource segmented in advance, then to the piecemeal resource of mapping hit using corresponding in piecemeal check information Check value is verified, and by corresponding sub-block resource if verifying successfully, requesting node requested resource data portion is distributed Requesting node is given, to realize in the case where not needing to carry out completeness check to entire resource, so that it may to each piecemeal Resource is verified and is shared, and the sharing rate of resource is improved.

Example IV

Based on the logical thought of resource sharing scheme shown in Fig. 2, as shown in fig. 6, it is shown in the embodiment of the present invention The method of calibration flowchart 2 of piecemeal resource, the main requesting node in P2P node shown in Fig. 2 of the execution of this method.Such as Shown in Fig. 6, the method for calibration of the piecemeal resource includes the following steps:

S610 sends resource download request to resource node, obtains in resources to be downloaded and be located in first interval information Resource data.

Wherein, it may also include the resource of resources to be downloaded other than including first interval information in the resource download request ID；The content of this step can be found in the content of step S510.

All first interval information of received resources to be downloaded are spliced to form second interval information by S620, and will Second interval information interval range corresponding with each piecemeal resource that resources to be downloaded are included is compared, and is determined and second Block information has the first piecemeal resource for being overlapped section；

When the playing request that requesting node is sent according to client App obtains resource from P2P network, it will usually under entire Load task is divided into multiple P2P tasks to complete the downloading of resource data.The data area downloaded every time, that is, correspond to said one Resource data in first interval information.The resource data for the first interval information that requesting node is downloaded each secondary P2P task Spliced, to complete the client App resource content to be played.Requesting node will be in each received first interval information Resource data spliced, so as to form resource data corresponding to a larger range of second interval information.Request Second interval information interval range corresponding with each piecemeal resource that resources to be downloaded are included is compared by node, and from Determine that there is the first piecemeal resource for being overlapped section with second interval information in each piecemeal resource.

For example, second interval information be [8KB, 25KB), the size of each piecemeal resource is 10K, then [8KB, 25KB) just Fallen in [0KB, 10KB), [10KB, 20KB), [20KB, 30KB) in piecemeal resource corresponding to these three interval ranges.This three A piecemeal resource is designated as the first piecemeal resource.

S630 uses preset school to the resource part being located in each first piecemeal resource in received resources to be downloaded Checking method carries out verification calculating respectively, obtains the 4th check value；

By in the corresponding resource data of second interval information, the resource part in each first piecemeal resource is mentioned It takes, such as in above-mentioned example [8KB, 10KB), [10KB, 20KB), [20KB, 25KB) the corresponding resource data of this three parts. Preset checking algorithm is respectively adopted in this three parts resource data and carries out verification calculating, obtains three check values, each school It tests value and is denoted as the 4th check value.

S640, by each 4th check value and same piecemeal resource in the piecemeal check information for the resources to be downloaded being locally stored Corresponding check value is compared, if identical, is overlapped section for having in corresponding piecemeal resource with second interval information Resource part save to local.

Wherein, piecemeal check information is after carrying out cutting to resources to be downloaded, to press respectively to each piecemeal resource of formation The default checking algorithm carries out that check value is calculated, and will be formed by character string after the splicing of these check values.

Wherein, cutting is carried out to a full resource to be formed used by process and the dicing process of multiple piecemeal resources Segmentation rules are detailed in the corresponding contents in step S320, and this will not be repeated here.

By each 4th check value obtained above and same point in the piecemeal check information for the resources to be downloaded being locally stored The corresponding check value of block resource is compared, such as will [8KB, 10KB) corresponding 4th check value, in piecemeal check information [0KB, 10KB) the check value of piecemeal resource be compared；Will [10KB, 20KB) corresponding 4th check value, it is verified with piecemeal In information [10KB, 20KB) the check value of piecemeal resource be compared；Will [20KB, 25KB) corresponding 4th check value, with In piecemeal check information [20KB, 30KB) the check value of piecemeal resource be compared.If two values compared are identical, recognize It is complete for the resource data currently downloaded, and will have the resource for being overlapped section in corresponding piecemeal resource with second interval information Part is saved to local.If two values compared are different, then it is assumed that the resource data currently downloaded is imperfect, and will be corresponding With second interval information there is the resource part for being overlapped section to abandon in piecemeal resource.

In practical application scene, the resource data that requesting node request plays is usually continuous, but data start bit It sets and is not necessarily just fallen in data end position on the boundary of a piecemeal resource, therefore in second interval range of information Resource data when being verified, the resource data of initial and end part is likely to cannot be by the verification of piecemeal check information.Therefore Can resource data to initial and end part without verification.The corresponding resource data of the 4th check value are calculated, can be broadcast from requested It puts in resource data, the initial data point in first complete piecemeal scope of resource starts, and complete being located at the last one The data point of piecemeal scope of resource end terminates.For example, for it is above-mentioned [8KB, 25KB) resource data in range, only calculate it In [10KB, 20KB) resource data in range the 4th check value, and to [8KB, 10KB), [20KB, 25KB) range Verification of the interior resource data without piecemeal check information.

In addition, can successively download number of resources from front to back by Data flow direction when requesting node downloads resource data According to after the partial data that one piecemeal resource of every downloading is included in this way, so that it may be verified to the part resource data using piecemeal Information is verified.

The method of calibration of the piecemeal resource of the embodiment of the present invention, requesting node provide the whole of same resource belonging to downloading Source data is mapped in each piecemeal resource segmented in advance, is then come out the piecemeal Resource Access of mapping hit and is used as first Piecemeal resource, and preset checking algorithm is used to the resource part being located in each first piecemeal resource in the resource data of downloading Verification calculating is carried out respectively, and is verified using the corresponding check value of piecemeal resource same in piecemeal check information, if school Testing successfully then will accordingly download resource conservation in local, not need to carry out completeness check to entire resource to realize In the case of, so that it may storage is verified and downloaded to each piecemeal resource, improves the sharing rate of resource.
