The embodiment of the present application discloses a kind of network resource configuration method, it is possible to be applied in the scene that software defined network (SoftwareDefinedNetwork, SDN) as shown in Figure 1 communicates.More fit the purpose of user's request to realize network, SDN controller described in Fig. 1 not only maintains original function thus ensureing network proper communication, also need to regularly collect customer service service condition by northbound interface, and obtain optimum subgraph annexation by the algorithm in optimum subgraph determination module, and then issue stream list item with reconstructed network topology based on the guidance of openflow agreement to switch by southbound interface.
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described embodiment is only some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of the application protection.
The disclosed a kind of network resource configuration method of the embodiment of the present application, as in figure 2 it is shown, comprise the following steps:
S201: obtain first network path.
In the present embodiment, first network path is whole optional network paths.
S202: obtain Consumer's Experience and describe information.
In the present embodiment, Consumer's Experience describes the acquisition mode of information and describes information list particularly as follows: obtain Consumer's Experience from user.
It is for instance possible to use following three kinds of modes obtain Consumer's Experience and describe information list: the first, provide brief user investigation questionnaire frame, user fill in feedback.
The second, by collecting user's historical operation daily record, analysis mining potential user's behavioural habits and environmental characteristic.
Specifically, User operation log information can frequently use time period of computer by user and user uses the type of service application to excavate the daily schedule periodic characteristics such as acquisition user's working entertainment and the deduction of the sex of this user or age bracket or even occupation type characteristic information in different time sections；Historical operation daily record can be also used for analyzing the response time obtaining user in the process user operation frequency with this application that use certain application (such as browser), user for more flourishing city, network condition causes that well user is also high to the expection of network service quality, therefore for identical network performance, if certain zone user same action average operation is more frequent, then illustrate that this zone user is higher to network service quality average expectancy.In addition physical region can also be divided for it by the address of specific acquisition user access network router.
3rd, gather plug-in unit in client configuration information, obtain client network handling capacity, traffic delay information etc..Specifically, the particular plug-in with monitoring users computer internet port information is installed, can give this plug-in unit corresponding function according to predetermined collection information, for instance: can monitor and add up the data traffic of process in certain port statistics time quantum for throughput information；The information that postpones is then that the transmission for each packet obtains with feedback time difference, and the packet of different business can be identified differentiation with Table Header information, from the transport layer of coarseness to fine-grained application layer.
S203: according to the mapping relations preset, it is that network performance describes information that Consumer's Experience describes information MAP, and performance Network Based describes information, it is thus achieved that screening conditions set.
In the present embodiment, as shown in Figure 3, the mapping relations preset include N number of Consumer's Experience and describe information, wherein, any one Consumer's Experience describes correspondence M application performance of information, correspondence P network performance of any one application performance, and the application performance corresponding with any one Consumer's Experience described is the restriction condition that this Consumer's Experience describes information, the restriction condition that network performance be this application performance corresponding with any one application performance described, N, M and P are the integer being not less than 1.Such as, the service access in Consumer's Experience information, it is subject to the service delay in application performance and the restriction of service response time, and service delay is subject to the restriction of the time delay in network performance and packet loss.It is to say, the Consumer's Experience in 3 is progressively decomposed, it is finally decomposed to the parameters in network performance.
In the present embodiment, according to general international standard, the network performance parameter of the bottom shown in Fig. 3 specifically includes that handling capacity, packet loss, time delay, delay variation, link utilization and the bit error rate；Application performance parameter specifically includes that service response time, service delay, service transmission rate and business packet loss；Consumer's Experience describes information and includes: service access, business instantaneity, business integrity, business retentivity and quality of service.
It should be noted that the parameter of each layer is not limited to described above in Fig. 3.Different types of business, it is necessary to the service feature index that emphasis considers would be likely to occur certain difference.It is to say, every kind of business itself has some intrinsic attributes, and these attributes require over different service feature indexs and realize, for instance: for session service, itself there is real-time characteristic, so needing emphasis to consider the time delay of business；For stream class service, emphasis is it is considered that the transfer rate of business；For interaction service, the main quality considering business, so needing emphasis to consider the key element such as service response time and service delay；For background business, the main accuracy considering whole business, so emphasis considers business packet loss.
Further, the sum of products of described M application performance and respective weighted value, represent that the Consumer's Experience that described M application performance is corresponding describes information.Described P network performance and the sum of products of respective weighted value, represent the application performance that described P network performance is corresponding.Conversion weight between the parameter at the two ends on the letter representation limit on each limit in Fig. 3.For same limit, different business can use different weighted values.
Can mutually change between information, application performance and network performance three from figure 3, it can be seen that Consumer's Experience describes.The information of known any one layer, all can obtain the parameter information of other layer of correspondence.The present embodiment obtain after Consumer's Experience describes information, according to Fig. 3, it is possible to be converted into network performance, each network performance parameter obtained, as screening conditions, form screening conditions set.
S204: based on screening conditions set, selects the second network path from described first network path.
Namely according to each network performance parameter, from first network path, the second network path is selected so that the second network path meets each network performance parameter.
Can be seen that from said process, in the present embodiment, by default mapping relations, it is possible to the information that described by Consumer's Experience is converted to concrete network performance parameter, and select network path according to network performance parameter, so that the network path selected meets the expection of Consumer's Experience.
The embodiment of the present application another network resource configuration method disclosed, compared with the embodiment shown in Fig. 2, one of difference is for after selecting the second network path, it is possible to according to the ruuning situation of the second network path, closed loop instructs the selection of the 3rd network path.
As shown in Figure 4, comprise the following steps:
S401: obtain first network path.
In the present embodiment, it is possible to use the mode of " doing one's best " of the prior art selects first network path in all possible network path from the Forwarding plane shown in Fig. 1.
Specifically, according to Network resource allocation and service condition, it then follows do one's best and service is sent to user and makes full use of the principle of Internet resources, select first network path from all possible network path.The first network path selected can be a plurality of.
S402: obtain Consumer's Experience and describe information.
In the present embodiment, unlike the embodiments above is, it is possible to according to being coated with the mapping relations preset shown in 3, calculates from network performance and/or application performance and obtains Consumer's Experience and describe information, namely first determine network performance, then foundation network performance simulation goes out Consumer's Experience and describes information.
S403: according to the mapping relations preset, it is that network performance describes information that described Consumer's Experience describes information MAP, describes information based on described network performance, it is thus achieved that screening conditions set.
The specific implementation of S403 may refer to S203, repeats no more here.
S404: according to the type of the business that described second network path will carry, distribute priority for each network performance in described screening conditions set.
S405: according to priority order from high to low, use each network performance described in described screening conditions set successively, select the second network path from described first network path.
When network performance parameter can not all be taken into account, it is possible to according to priority, pay the utmost attention to the network parameter that priority is high.
S406: detect and run the network service user experience information of business whether in default threshold range by described second network path, if it is, terminate or periodically perform S406, if it does not, perform S407.
Specifically, the calculation of the network service user experience information that the second network path runs business is: by calculating the sum of products of the proportion that the quality of each business takies in described network with each business described, obtain described network service user experience information.
Such as: in certain period, 80% user is using session service, 15% user is using stream class service, and 5% user is using background business, the network service user experience information=85%*Q in this time periodsession(Ai)+15%*Qstreaming(Ai)+5%*Qbackground(Ai)。
Wherein, Qsession(Ai) represent session service quality, Qstreaming(Ai) represent stream class service quality, Qbackground(Ai) represent background business quality.
Specifically, the quality of any one business thus business is relevant in described default mapping relations network performance and the sum of products of the respective weighted value of described relevant network performance calculate and obtain, for instance: business AiQuality Q uality (Ai)=r1*Qd(Ai)+r2*Ql(Ai)+r3*Qt(Ai)+r4*Qj(Ai), wherein
QdTransmission delay (transmissiondelay)
QlPacket loss (packetlossrate)
QtHandling capacity (throughoutput)
QjDelay variation (jitter)
Different types of application is for identical Consumer's Experience, and in delay, packet loss, handling capacity, shake, performance requirement stresses difference, therefore coefficient of utilization ri(i=1,2,3,4 and ∑ ri=1) represent map after each network performance for the weighing factor size of different business Consumer's Experience.Coefficient riIt is the weighted value shown in Fig. 3.
Such as, session service itself has real-time characteristic, so needing emphasis to consider the time delay of business, corresponding r4 should be maximum；In like manner stream class service emphasis is it is considered that the transfer rate of business, and corresponding r3 should be maximum；Background business emphasis is it is considered that the integrity of business, and corresponding r2 should be maximum, and concrete weights magnitude relationship can be determined after historical data learns.
