Below by specific embodiment, the embodiment of the present invention is described in detail.
Fig. 1 is a kind of flow diagram of resource share method provided in an embodiment of the present invention；The method can be applied
Resource identification information punishment corresponding with the corresponding relationship of node and node is previously stored in server, the server
Time cut off, the method may include steps:
S101: the resource request instruction that requesting node is sent is received, includes at least described ask in the resource request instruction
The identification information for the target resource for asking node to request and the identification information of the requesting node；
It will be appreciated by persons skilled in the art that so-called P2P network, i.e. peer-to-peer network, are one kind in fellow
(Peer) the Distributed Application framework that task and workload are distributed between, is one kind that P2P computing model is formed in application layer
Networking or latticed form.Therefore, peer-to-peer network (Peer-to-peer networking) or P2P computing be can be described as from literal
(Peer-to-peer computing), can be with is defined as: the participant of network shares a part of hardware that they are possessed
Resource (processing capacity, storage capacity, network-connectivity, printer etc.), these shared resources by network offering services and
Content can directly be accessed by other peer nodes (Peer) without being subjected to intermediate entities.Participant in this network is both
The supplier (Server) of resource, service and content, and be that resource, service and content obtain taker (Client).
In P2P network environment, all in the status of equity between the multiple stage computers that are connected to each other, each computer has
Identical function, no master-slave.Each computer in network can serve as network service requestor and other meters
The request of calculation machine responds, and provides resource, service and content.These usual resources and service include: the shared of information and hand over
It changes, computing resource (such as CPU computing capability is shared), storage shared (such as the use of caching and disk space), network share, printing
Machine is shared etc..
For any one node in P2P network, resource request instruction, commonly referred to as transmission resource can be sent
The corresponding node of request instruction is requesting node, for resource request instruction, includes at least request in resource request instruction
The identification information of the target resource of node request and the identification information of the requesting node；It is understood that in P2P network
In, each resource will correspond to an identification information, for example, resource A, resource B, resource C, resource D, resource E are respectively corresponded
Identification information is zy10000001, zy10000010, zy10000011, zy10000100, zy10000101；Likewise, for
For node in P2P network, each node also corresponds to an identification information, and identification information can be the corresponding link of node
Address, for example, node 1, node 2, node 3 and node 4 respectively correspond identification information be 192.168.1.101,
192.168.1.102,192.168.1.103 and 192.168.1.104；Certainly, it above are only provided in an embodiment of the present invention one
The example of kind specific resource identification information and node identification information, the application do not believe resource identification information and node identification
The form of expression of breath, which is done, clearly to be limited, as long as being able to achieve one-to-one relationship.
Requesting node sends resource request and instructs to server, and server receives the resource request that requesting node is sent and refers to
It enables, for example, the received resource request instruction of server is the request to target resource C that requesting node 2 issues, then asking at this time
It asks to include at least in instruction and has the corresponding mark letter of 2 corresponding identification information 192.168.1.102 and target resource C of requesting node
Cease zy10000011.It should be noted that the embodiment of the present invention does not do further limit to requesting node and requested resource
It is fixed.
S102: judge that the requesting node sends resource request and instructs whether corresponding time point is in the requesting node
Before corresponding Penalty time cut off；If not, executing step S103.
It is worth noting that being stored with a Penalty time cut off corresponding with P2P nodes in the server
Table, i.e., each node will correspond to a Penalty time cut off in P2P network, understandable to be, according to requesting node pair
The Penalty time cut off answered judges, if current point in time is in front of the corresponding Penalty time cut off of the node, then
Illustrate that the node is receiving punishment, at this point, the node, which is issued resource request instruction, will cannot get the response of server.Cause
This, server needs to judge that requesting node sends resource request and instructs whether corresponding time point is in this stored in server
Before the corresponding Penalty time cut off of requesting node.
S103: when according to the identification information of the target resource, the corresponding relationship and the corresponding punishment of the node
Between cut off, determine node to be contributed；
It is understandable to be, judge that requesting node sends resource request and corresponding time point is instructed not locate in above-mentioned server
When before the corresponding Penalty time cut off of the requesting node stored in server, server is asked according to the resource received
The identification information for seeking the target resource in instruction, corresponding relationship and node pair in server between the resource stored and node
The Penalty time cut off answered provides a node to be contributed for requesting node, specifically, server is according to the resource received
The identification information of target resource in request instruction is looked into the corresponding relationship of resource identification information and node that server stores
It looks for, finds out the node for including the requested target resource of requesting node and the corresponding Penalty time of the node is being requested by point
Node is sent before resource request instruction.
In order to facilitate understanding, first assume that requesting node 2 asks target resource C what time point am11:10:25 was issued
It asks, has requesting node 2 corresponding then server includes at least in the resource request instruction that time point am11:10:25 is received
Identification information 192.168.1.102 and the corresponding identification information zy10000011 of target resource C, by the money stored in server
Source identification information Penalty time cut off corresponding with the corresponding relationship of node and node is it is known that node 1
It include resource A (zy10000001), resource B (zy10000010), resource C (zy10000011), section in (192.168.1.101)
1 corresponding Penalty time cut off of point is am11:10:05；It include resource A in node 2 (192.168.1.102) i.e. requesting node
(zy10000001), resource B (zy10000010), resource D (zy10000100), the corresponding Penalty time of node 2 are by point
am11:10:00；It include resource B (zy10000010), resource C (zy10000011), D in node 3 (192.168.1.103)
(zy10000100), the corresponding Penalty time cut off of node 3 is am11:10:30；Include in node 4 (192.168.1.104)
Resource A (zy10000001), resource D (zy10000100), resource E (zy10000101), the cut-off of the corresponding Penalty time of node 3
Point is am11:10:20.
Requesting node 2 send resource request instruct corresponding time point the corresponding Penalty time of requesting node 2 by when
Between put after, server receive requesting node 2 transmission resource request instruction, according to resource request instruct in include target
The corresponding identification information zy10000011 of resource C is looked into the corresponding relationship of resource identification information and node that server stores
It looks for, can obtain the node comprising target resource C has node 1, node 3, but the corresponding Penalty time of node 3 is by point
Am11:10:30 is sent after resource request correspond to time point in requesting node 2, and node 3 is also receiving punishment, cannot function as to
Resource node is contributed, therefore node 1 is determined as node to be contributed by server.
S104: it sends to the node to be contributed for inquiring whether the node to be contributed is ready to the requesting node
The inquiry instruction of the target resource is provided；
Server to node 1 to be contributed send inquiry instruction, inquiry instruction for inquire node 1 to be contributed whether be ready to
Requesting node 2 provides target resource C.In practice, server includes two choosings into the inquiry instruction that node 1 to be contributed is sent
, respectively " receive " and " refusal ", for example, mobile terminal device (such as mobile phone) is actually a node, server can
Inquiry instruction is sent to node 1 (mobile phone) to be contributed by network, two buttons " receiving " and " refusal " on mobile phone are provided and come
Realize the process of inquiry, naturally it is also possible to it is asked whether to be ready the resource that shared node includes to node by other forms,
The application does not do the concrete form of inquiry and clearly limits.
S105: whether judgement receives the node to be contributed for the inquiry instruction feedback within a preset period of time
Response instruction executes step S106 if be not received by；Wherein, if be not received by within a preset period of time it is described to
Node is contributed for the response instruction of the inquiry instruction feedback, indicates that the node to be contributed is reluctant requesting node described in intention
The target resource is provided；
In practice, it is contemplated that the response time of network, the embodiment of the present invention preset a period to judge wait contribute section
Whether point responds for the inquiry instruction that server is sent, it is to be understood that if within a preset period of time, wait contribute
Node is made that response for the inquiry instruction that server is sent, then a response instruction will be sent by being somebody's turn to do node to be contributed, and is used to
The tell the server node to be contributed is ready to provide target resource to requesting node.If node to be contributed is reluctant intention request section
Point provides target resource, that node to be contributed does not send response instruction.
For example, preset time period is 2 seconds, the calculation delay of server is not considered, it is corresponding that requesting node 2 sends resource request
Time point be am11:10:25, then server receive resource request instruction with to node to be contributed send inquiry instruction pair
The time answered is considered am11:10:25, then server will judge be in period am11:10:25-am11:10:27
The no response instruction for receiving node 1 to be contributed and feeding back.It is worth noting that for the embodiment of the present invention, if when
Between in section am11:10:25-am11:10:27, node 1 to be contributed both did not had " to receive " or did not had " to refuse ", at this time wait contribute section
Point does not send response instruction yet, and server is not received by the response that node 1 to be contributed is fed back, it also hold that node to be contributed
1 is reluctant that intention requesting node 2 provides target resource.
S106: determine that the node to be contributed does not feed back the number of response instruction continuously；
If it is anti-that server is not received by node 1 to be contributed in preset period am11:10:25-am11:10:27
The response of feedback instructs, then server will record its frequency n for not feeding back response instruction continuously for node 1 to be contributed, specifically
, may exist a counter in server, it is now assumed that when server receives the response instruction wait contribute node 1 to feed back,
Counter low level resets, when server is not received by the response instruction wait contribute node 1 to feed back, counter high level meter
Number；Certainly there can also be many specific implementations to count the number that node to be contributed does not feed back response instruction continuously, originally
Embodiment is not to determining that node to be contributed do not feed back the specific implementation of number of response instruction continuously and further limit.
S107: it according to the number, calculates and is directed to the corresponding Penalty time of the node to be contributed；
Server is according to the above-mentioned fixed frequency n for not feeding back response instruction continuously for node 1 to be contributed, Ke Yiji
It calculates wait contribute node continuous n-th to correspond to the Penalty time of n-th, understandable, punishment when not feeding back response instruction
Time can be the product of preset time and frequency n, and Penalty time can also be the exponential function about frequency n.The application is not
Its specific manifestation form is further limited.
In practical application, calculates and is directed to the corresponding Penalty time of the node to be contributed, comprising:
According to formula: Penalty time=preset time * bn, calculate and be directed to the corresponding Penalty time of the node to be contributed；
Wherein, b > 1, n are the number that the node to be contributed does not feed back response instruction continuously.
Under normal conditions, Penalty time TBWith indicating, preset time T0It indicates, the calculation formula that can obtain Penalty time is
TB=T0*bn, in formula, n is the number that the node to be contributed does not feed back response instruction continuously, and b is the truth of a matter, and the size of b is very big
Penalty time T is influenced in degreeBVariation tendency between frequency n, it is understandable to be, in order to motivate node to be contributed to asking
It asks node to provide target resource, needs that b > 1 is arranged, so that the Penalty time T of node to be contributed 1BWith the increase of frequency n
It is increasing；If when b < 1, Penalty time TBAs the increase of frequency n is smaller and smaller instead, it is clear that cannot in b < 1
It plays and node to be contributed is motivated to provide the purpose of target resource to requesting node.
For example, preset time T0=5 seconds, b=1.19, it is assumed that node 1 to be contributed refers to for continuous 4 times without feedback response
It enables, then, by Penalty time calculation formula TB=T0*bnIt is not difficult to calculate the continuous the 4th of node 1 to be contributed and does not feed back response
Instruct corresponding Penalty time TBIt is 10 seconds, here presetting at time and number and the truth of a matter certainly all is a kind of specific example, needle
Difference also can be set to each node truth of a matter to be contributed, the embodiment of the present invention does not further limit it.
S108: it according to the Penalty time and current point in time, determines and stores that described node to be contributed is corresponding punishes
Time cut off, and the resource that the node push resource price to be contributed described in the forward direction of the Penalty time cut off is high are penalized,
To reduce the corresponding Penalty time cut off of the node to be contributed.
It is not difficult to obtain Penalty time by above-mentioned, it is understandable to be, contribution node 1 is treated since current point in time to be made
Punishment, Penalty time terminates corresponding Penalty time cut off=current point in time+Penalty time, by calculated Penalty time
Cut off stores Penalty time cut off position corresponding with node to be contributed in the server, and Penalty time before is ended
Point deletion.For example, having determined that the continuous the 4th of node 1 to be contributed does not feed back response to instruct corresponding Penalty time is 10 seconds,
Current point in time is am11:10:27, then being not difficult to calculate the corresponding Penalty time cut off of node 1 to be contributed to be am11:
Am11:10:37 is stored Penalty time cut off position corresponding with node to be contributed in the server by 10:37, will be wait contribute
The last corresponding Penalty time cut off am11:10:05 of node 1 is deleted.
When actually treating contribution node punishment, in the corresponding Penalty time cut off am11:10:37 of node 1 to be contributed
Before, server can give the high resource supplying of P2P resources in network price to node 1 to be contributed, and node 1 to be contributed can be at this time
Reduce the corresponding Penalty time cut off of node 1 to be contributed by the resource of download server push.For example, current point in time
The high resource E of resource price is pushed to node 1 to be contributed by am11:10:30 server, if node to be contributed 1 receives push
The high resource E of resource price after, when having selected downloading, server will the corresponding time cut off am11:10 of node be contributed:
37 reduce 5 seconds, become am11:10:32, and by the Penalty time cut off am11:10:32 storage after reduction in the server with
The corresponding Penalty time cut off of node to be contributed position, will the last corresponding Penalty time cut off of node 1 be contributed
Am11:10:37 is deleted.If node 1 to be contributed does not select to download, the corresponding Penalty time cut off of node to be contributed

In the case that the node to be contributed that requesting node is sent has shared the message of the target resource, changed according to default credit value
Become rule, changes the credit value of the requesting node and the node to be contributed.
In practice, server can require requesting node to feed back a message after obtaining target resource, that is, if request
After the completion of node obtains target resource, the message that an identification request node has acquired target resource is sent, to remind clothes
Business device node to be contributed has shared target resource to it；In order to preferably motivate node can shared resource, the present embodiment
A credit value, the corresponding credit value of each node also are provided for each node, credit value is used to characterize its corresponding node letter
Reputation degree size.But when contributing resource and request resource is completed, corresponding credit value will change node, be easy reason
Solution, when completing resource request, the corresponding credit value of requesting node will reduce requesting node accordingly, and node to be contributed is in tribute
Offering the corresponding credit value of node to be contributed after resource will accordingly increase.For example, the initial credit value of node 1-4 is 0, if
Requesting node 2 from wait contribute in node 1 obtain target resource after, correspondingly, node 1 credit value increase by 1, the prestige of node 2
Value reduces 1, therefore the corresponding credit value size of node 1-4 is respectively as follows: 1, -1,0,0.Certainly, the above-mentioned credit value increase that is directed to subtracts
Few numerical value is a kind of specific example provided in this embodiment, increases and the size of reduction can also be a kind of relational expression, this
Application, which is not done its concrete form, clearly to be limited.
In practical applications, rule is changed according to default credit value, changes the requesting node and the node to be contributed
Credit value, comprising:
The credit value of the requesting node is reduced into C-, whereinIn formula, A
Coefficient is reduced to be default, K is resource base price, NA(m, t) is unit interval of the target resource m before current time t
Interior requested number, NE(m, t) is the number of nodes that current time t contains target resource m；
The credit value of the node to be contributed is increased into C+, whereinα > 0, formula
In, K is resource base price, riFor the shared resource number of the node i to be contributed, NA(m, t) is target resource m current
Requested number, N in unit interval before moment tE(m, t) is the number of nodes that current time t contains target resource m
Amount.
Under normal conditions, claimFor the well sold and in short supply degree of target resource m, indicated with b (m, t)；ClaimFor mesh
The resource price function for marking resource m is indicated with p (m, t), indicates target resource m in the corresponding resource price of moment t；ClaimFor the contribution coefficient of node to be contributed, with f (ri) indicate, work as riWhen=0, f (ri)=0.And work as riCertain journey is arrived greatly
F (r after degreei) tend to 1.The contribution coefficient function f (r under different parametersi) with the shared resource number r of node i to be contributediPair
It should be related to as shown in Figure 4.From the content that Fig. 4 is shown it is not difficult to find that when α value is smaller, such as α=1, functional image compare
Gently.I.e. contribution coefficient gradually increases as node contributes increasing for resource quantity.When α value is larger, for example, α=8, function
Image steeper.After contribution margin is greater than 1, the variation of contribution coefficient tends towards stability and moves closer in 1.It is reduced for default
Coefficient A can be adjusted according to the operating status of network, such as A=1/2, A=2/3 etc., the embodiment of the present invention be not right
The specific value of default reduction ratio A, which is done, clearly to be limited.
For example, the initial credit value of node 1-4 is 0, if requesting node 2 obtains target money from node 1 to be contributed
Behind source, reduce C using the credit value of above-mentioned requesting node 2-Formula calculates, and obtains the corresponding prestige of requesting node 2 and reduces C-=
0.8, increase C using the credit value of above-mentioned node to be contributed+Formula calculates, and obtains the corresponding prestige of node 1 to be contributed and increases C+=
1.0；So the corresponding credit value of node 1-4 is respectively as follows: 1, -0.8,0,0 at this time.
In embodiment provided by the invention, requesting node is the node that credit value is not less than preset threshold.
Understandable to be, in P2P network, each node corresponds to a credit value, if credit value very little, small
When a numerical value, generally it can be thought that this node is unworthy trusting, server no longer will provide request service for the node,
For example, preset threshold is -1, and the corresponding credit value size of node 1-4 at this time in P2P network is respectively as follows: -1, -1.5,0.5,
2, then when node 2 cannot send resource request instruction.It is only that the embodiment of the present invention provides that preset threshold among the above, which takes -1,
Example, the embodiment of the present invention do not do the specific value of preset threshold and clearly limits.
