Under a kind of possible application scenarios, after terminal 110 accesses WiFi network, i.e., speed is downloaded to WiFi network Test, and data relevant to test result are reported into server 130.Server 130 receives the number that each terminal reports According to rear, identify whether each WiFi network opens speed limiting function by speed limit testing mechanism, and further speed limit function is opened in identification Speed limit mode used by the WiFi network of energy.The speed limit mode that terminal 110 is used according to current WiFi network, using corresponding Acceleration strategy carries out network access, to evade WiFi network speed limit, improves the rate of network access.

It further include at least domain name system (DNS, a DNS) clothes under a kind of possible application scenarios, in the implementation environment Business device 140.Optionally, the corresponding relationship being stored in server 130 between each WiFi network and dns server, terminal 110 The corresponding target dns server of current WiFi network is obtained i.e. from server 130, and DNS request is sent to target DNS clothes It is engaged in device, wherein target dns server is delay and the minimum dns server of packet loss under current WiFi network connection status.

It further include transmission control protocol (Transmission in the implementation environment under other possible application scenarios Control Protocol, TCP) accelerate server 150 and network resource server 160, which accelerates server 150 and end End 110 is connected, and is connected with the requested network resource server 160 of terminal 110 (for providing network service).Optionally, TCP accelerates server 150 to accelerate service for providing, to improve the slow turn-on speed of TCP.

In the related technology, it after terminal access WiFi network, can be tested the speed by downloading, ping value assesses current WiFi net The Network status of network can also be cheated by such as address resolution protocol (Address Resolution Protocol, ARP) The detection modes such as detection and honey jar detection determine the safety of current WiFi network.But aforesaid way can not improve currently The availability of WiFi network.For example, terminal can not determine itself by the above method when WiFi network enables speed limiting function Whether by speed limit, and itself network access speed can not be improved by speed limit.

In order under the premise of not influencing other access terminals, improve the availability of WiFi network, in the embodiment of the present application, DNS accelerating module 111 is provided in terminal 110, speed limit evades module 112 and TCP accelerating module 113.Wherein, it is carrying out When dns resolution, terminal 111 by DNS accelerating module 111 locally realize domain name mapping, or, by DNS accelerating module 111 with Server 120 interacts, and determines the optimal dns server 140 under current WiFi network environment, is carried out by dns server 140 Domain name mapping, to reduce dns resolution time-consuming；After accessing WiFi network, terminal 110 evades module 112 and service by speed limit Device 120 interacts, and determines the speed limit mode that current WiFi network uses, thus using the corresponding speed-raising strategy of the speed limit mode Network speed-raising is carried out, WiFI network speed limit is evaded；In TCP slow start stage, terminal 110 passes through TCP accelerating module 113 and TCP Accelerate server 150 to interact, shortens TCP slow turn-on duration by the acceleration function that TCP accelerating module 113 provides, thus Improve the speed that network resource server 160 sends data.

Referring to FIG. 3, the flow chart of the WiFi network access method provided it illustrates the application one embodiment.This reality Example is applied to come applied to terminal 110 shown in FIG. 1 for example, this method may include following several with the WiFi network access method A step:

Step 301, when accessing target WiFi network, whether identification target WiFi network opens speed limiting function, speed limit function Access speed after capable of being used for limiting terminal access target WiFi network.

Optionally, terminal is using local speed limiting function detection mode, or, whether identifying target WiFi network by server Open speed limiting function.

WiFi network generallys use the speed limit mode based on terminal and carries out speed limit, for example, WiFi network opens IP address section The simple speed limiting function such as speed limit and MAC Address speed limit carries out speed limit to designated terminal.

In a kind of possible embodiment, dynamic host configuration is not forced in the routing device for providing target WiFi network In the case where agreement (Dynamic Host Configuration Protocol, DHCP), terminal is laggard using replacement static IP Whether the mode that row tests the speed, identification target WiFi network open speed limiting function.

Optionally, under different static ip address, the speed difference of target WiFi network is greater than threshold value, it is determined that target WiFi network opens speed limiting function.

In order to improve the accuracy and efficiency of speed limiting function detection, in alternatively possible embodiment, terminal access WIFi network and after being tested the speed, will test relevant data and reports to server, reported by server according to each terminal Data determine whether WiFi network opens speed limiting function.After subsequent other terminals access target WiFi network, by with server Interact the unlatching situation that can recognize target WiFi network speed limiting function.

If target WiFi network opens speed limiting function, terminal executes following step 302；If target WiFi network does not open limit Fast function, terminal directly carry out network access by WiFi network.

Step 302, if target WiFi network opens speed limiting function, it is determined that the speed limit mode that target WiFi network uses, Speed limit mode includes at least one of IP sections of speed limits, MAC Address speed limit, port speed constraint and agreement speed limit.

In order to know which kind of speed limit mode target WiFi network uses, carried out so as to subsequent using corresponding acceleration strategy Evade, after identifying that target WiFi network opens speed limiting function, terminal further determines that its speed limit mode used.

Optionally, when terminal identifies that target WiFi network opens speed limiting function using local speed limiting function detection mode When, terminal determines the speed limit mode used according to local recognition result；When terminal is opened by server identification target WiFi network When opening speed limiting function, terminal further obtains the speed limit mode that target WiFi network uses from server.

Step 303, network access is carried out according to the corresponding acceleration strategy of speed limit mode.

According to the speed limit mode that target WiFi network uses, terminal carries out net after evading speed limit using corresponding acceleration strategy Network access.Optionally, which is stored in advance in terminal, or, being issued by server.

In conclusion in the present embodiment, when accessing WiFi network, by identifying whether current WiFi network opens speed limit Function, and when current WiFi network opens speed limiting function, further determine that speed limit mode used by current WiFi network, from And network access is carried out based on the corresponding acceleration strategy of the speed limit mode；Due to using acceleration strategy can evade IP sections of speed limits, MAC Address speed limit, port speed constraint or agreement speed limit, thus terminal carry out when internet access the bandwidth that can use will not be by The limitation of WiFi network speed limit strategy, and then improve the internet access speed of terminal.

Under a kind of application scenarios, terminal to server reports the mode of test data, is based on a large amount of tests by server Data identify that the speed limiting function of each WiFi network is opened situation and stored.In subsequent process, terminal by with server Interacting can quickly determine whether current WiFi network opens speed limiting function.It is said below using schematical embodiment It is bright.

Referring to FIG. 4, the flow chart of the WiFi network access method provided it illustrates another embodiment of the application.This Embodiment is applied to terminal 110 shown in FIG. 1 with the WiFi network access method and comes for example, this method may include following Several steps:

Step 401, when accessing target WiFi network, speed limit inquiry request is sent to server, in speed limit inquiry request Mark comprising target WiFi network.

After terminal accesses target WiFi network, i.e., the speed limit inquiry of the mark comprising target WiFi network is sent to server Request, wherein target WiFi network be identified as Basic Service Set Identification (Basic Service Set Identifier, ) or service set (Service Set Identifier, SSID) BSSID.

In the present embodiment, server is stored with the corresponding relationship between WiFi network and speed limit marker, the corresponding relationship The Test data generation reported after each (access WiFi network) terminal is tested is based on by server, which uses In the open state of characterization speed limiting function.Wherein, terminal carries out test and the process of server generation corresponding relationship will be rear It is described in detail in continuous step, details are not described herein for this step.

Optionally, server is that corresponding numerical value is arranged in the speed limit marker of WiFi network, to pass through numerical representation method The unlatching situation of WiFi network speed limiting function.For example, for the WiFi network for opening speed limiting function, server identifies its speed limit The value of position is set as 1；For not opening the WiFi network of speed limiting function, the value of its speed limit marker is set as 0 by server；For limit Fast function open WiFi network in confused situation (such as it is less according to the test data that terminal reports, can not determine speed limiting function Open situation), the value of its speed limit marker of server is set as empty (null).

Schematically, the corresponding relationship between WiFi network and speed limit marker is as shown in Table 1.

Table one

The mark of WiFi network	Speed limit marker
		WiFi001	0
WiFi002	1
		WiFi003	null

As shown in figure 5, terminal 52 sends inquiry to server 53 and asks after the target WiFi network that couple in router 51 provides It asks.

Step 402, the query result of server feedback is received, includes speed limit marker in query result.

After receiving inquiry request, server is the mark according to target WiFi network, is inquired from above-mentioned corresponding relationship The corresponding speed limit marker of target WiFi network, and the query result comprising speed limit marker is fed back into terminal.

As shown in figure 5, mark of the server 53 according to target WiFi network in inquiry request, from database 531, inquiry The corresponding speed limit bit identification of target WiFi network, and corresponding query result is fed back to terminal 52.

Step 403, if the value of speed limit marker is not sky, identify that target WiFi network is according to the value of speed limit marker No unlatching speed limiting function.

For the query result received, whether the value of speed limit marker is sky in terminal detection query result, if speed limit The value of marker is sky, indicates that server can not temporarily determine whether target WiFi network opens speed limiting function, under terminal executes State step 406；If the value of speed limit marker is not sky, terminal further according to the value of harness marker, determines target WiFi net Whether network opens speed limiting function.

In a kind of possible embodiment, in conjunction with the example in step 401, when the value of speed limit marker is 0, terminal Determine that target WiFi network does not open speed limiting function；When the value of speed limit marker is 1, terminal determines that target WiFi network is opened Speed limiting function.

Optionally, server can also be according to the value of the speed limit marker inquired, directly to terminal feedback target WiFi The speed limiting function of network opens situation (including open, do not open, is unknown), and the present embodiment is defined not to this.

Step 404, if target WiFi network opens speed limiting function, it is determined that the speed limit mode that target WiFi network uses.

Optionally, the speed limit mode that target WiFi network uses includes at least one.

In a kind of possible embodiment, when server receives the test data that each terminal reports, end is also received The associated data reported is held, when determining the unlatching situation of WiFi network speed limiting function based on test data, further according to pass Connection data determine speed limit mode used by WiFi network.Correspondingly, speed limit mode of the server to WiFi network and its use Be associated storage, and when target WiFi network opens speed limiting function, the speed limit mode that target WiFi network is used as Query result feeds back to terminal together.

Schematically, the corresponding relationship of WiFi network and speed limit mode is as shown in Table 2.

Table two

The mark of WiFi network	Speed limit marker	Speed limit mode
			WiFi001	0	-
WiFi002	1	IP sections of speed limits
			WiFi003	null	-

Correspondingly, terminal can obtain the speed limit mode of target WiFi network use from query result.

Wherein, terminal reports associated data and server to determine that the process of speed limit mode will be described in detail in the next steps, Details are not described herein for this step.

Step 405, network access is carried out according to the corresponding acceleration strategy of speed limit mode.

Since WiFi equipment can be directed to heterogeneous networks level, using different speed limit means, therefore, for different limits Fast mode, terminal needs to evade speed limit using different acceleration strategies, and in a kind of possible embodiment, this step includes such as Lower step.

One, when speed limit mode is IP sections of speed limits, setting carries out network visit after belonging to non-throttling IP sections of static ip address It asks, non-throttling IP sections is downloaded the associated data reported after velocity test according to each terminal by server and generated.

When determining target WiFi network using IP sections of speed limits, due to the speed limit mode only to specified IP sections of terminal into Row speed limit, therefore, terminal pass through the static ip address for modifying itself, so that modified static ip address belongs to non-throttling IP Section, and then carry out network access.

For non-throttling IP sections of method of determination, in a kind of possible embodiment, each terminal is downloaded speed After test, the test data identified comprising speed of download and WiFi network is reported to server, and include static ip address Associated data, server are determined by the speed of download of the terminal under the identical WiFi network of analysis, different static ip address WiFi network is speed limit IP sections corresponding, and then is determined according to IP sections of speed limit IP sections non-throttling, wherein IP sections of speed limit lower terminals Speed of download is less than the speed of download of non-throttling IP sections lower terminal, and IP sections of speed limit of accuracy is in the data volume that terminal reports Positive correlation.

Optionally, IP sections non-throttling (or IP sections of speed limit) is sent to terminal by server.Terminal detects current IP address It is no belong to it is IP sections non-throttling, if belonging to, directly progress network access；If being not belonging to, set itself static ip address to Some IP address in IP sections non-throttling, and carry out network access.

For example, it is 192.168.1.10-192.168.1.20 that terminal, which gets target WiFi network to correspond to non-throttling IP sections, And the static ip address of itself be 192.168.1.22 when, carried out after the static ip address of itself is revised as 192.168.1.15 Network access.

Two, when speed limit mode is MAC Address speed limit, network access is carried out after modifying MAC Address.

Similar with IP sections of speed limits, when own MAC address belongs to speed limit MAC Address, terminal modifies own MAC address To access after non-throttling MAC Address.

For the method for determination of speed limit MAC Address, in a kind of possible embodiment, each terminal is downloaded speed After test, the test data identified comprising speed of download and WiFi network, and the association comprising MAC Address are reported to server Data, server determine WiFi network by the speed of download of the terminal under the identical WiFi network of analysis, different MAC Address Corresponding speed limit MAC Address.

Optionally, speed limit MAC Address is sent to terminal by server.Whether terminal detection own MAC address belongs to speed limit MAC section, if being not belonging to, directly progress network access；If belonging to, set own MAC address to other than speed limit MAC Address MAC Address, and carry out network access.

Speed limit can not be evaded in order to avoid because of the ARP table stored, leading to only to modify IP address or MAC Address in WiFi equipment The problem of, optionally, terminal modifies itself static ip address and MAC Address simultaneously.

Three, when speed limit mode is port speed constraint, the port numbers in network request is modified and carry out network access.

In a kind of possible embodiment, when target WiFi network is by the way of based on port speed constraint, limitation is certain When the well known port of application, the port numbers being sent in the network request of well known port are revised as standby port by terminal, and are sent Modified network request realizes network access.Optionally, it is corresponding to obtain well known port from the configuration file of application for terminal Standby port.

For example, terminal is being sent when target WiFi network limits well known port http://sz1-7.xxx.com:8000 When network request, port numbers 8000 are revised as standby port number 8001, i.e., network request are revised as http://sz1- 7.xxx.com:8001。

Four, when speed limit mode is agreement speed limit, network request is forwarded to proxy server, proxy server is used for will Network request is forwarded to the corresponding network resource server of network request, and the data for forwarding network resource server to send.

When WiFi equipment is by the way of agreement speed limit, and limitation uses the service of certain agreements, terminal passes through agency's Network request is sent to uncurbed proxy server by mode, and network request is forwarded to network money by proxy server Source server, and the data of Receiving Agent server forwarding, to evade agreement speed limit.

Other than above-mentioned four kinds of speed limit modes, target WiFi network can also carry out terminal speed limit using other modes, than The speed of download of download tool is such as limited by TCP connection number, the embodiment of the present application is defined not to this.

Step 406, if the value of speed limit marker is sky, it is downloaded velocity test, obtains speed of download.

Initial stage is identified in speed limit mode, since the test data that terminal reports is less, causes server can not be based on test Data determine the unlatching situation of WiFi network speed limiting function, at this point, the value of the speed limit marker of server feedback is sky.

In order to improve the coverage and accuracy of the identification of WiFi network speed limit, when the value of the speed limit marker received is When empty, terminal is downloaded velocity test under target WiFi network, obtains corresponding speed of download.

In a kind of possible embodiment, in order to ensure testing consistency, different terminals use identical downloading mode Same resource file is downloaded, to obtain corresponding speed of download.Optionally, which is to download being averaged for resource file Speed.

For example, when terminal is downloaded velocity test, the resource file time-consuming 10s that downloading size is 1M is calculated down Load speed is 0.1M/s.

Optionally, in order to improve the accuracys of data, terminal executes multiple speed of download test in different moments, and according to Repeatedly downloading result calculates speed of download.

Step 407, test data is reported to server, test data includes speed of download, the mark of WiFi network and survey Timestamp is tried, server is used for pair established between WiFi network and speed limit marker according to the test data that each terminal reports It should be related to.

Further, after completing speed of download test, terminal to server reports test data, in the test data at least It is stabbed including speed of download, the mark of WiFi network and testing time.

Optionally, in order to avoid the accuracy that WiFi quality of connection and/or network fluctuation influence test data, terminal is reported Test data in further include the data such as signal strength (being used to indicate quality of connection) and Ping value (being used to indicate network delay). Correspondingly, server, that is, trap signal intensity is lower than intensity threshold, and/or, Ping value is higher than the test data of threshold value.

Schematically, the test data that terminal reports is as shown in Table 3.

Table three

BSSID	Speed of download	Signal strength	Ping value	Testing time stamp
					WiFi003	0.1M/s	-75dbm	20ms	2018-1-18 14:27:20

During actual implementation, as shown in figure 5, great amount of terminals 53 (accessing identical or different WiFi network) by itself Test data reports to server 53, and server 53 analyzes a large amount of test datas, so that it is determined that different WiFi networks Speed limiting function open situation.

When inactive speed limiting function, the terminal downloads speed for accessing WiFi network can reach network maximum bandwidth and (not deposit In the case of contention)；And when enabling speed limiting function, the speed of download of the terminal of WiFi network is accessed there are a upper limit value, And the upper limit value is less than network maximum bandwidth.Therefore, server is by analyzing under same WiFi network, the downloading speed of different terminals Degree, that is, can determine whether the WiFi network opens speed limiting function.

In a kind of possible embodiment, server is obtained under same WiFi network, the test number that different terminals report According to, and according to the testing time stamp filter out target detection data, include: in the target detection data first terminal report first Speed of download a1 and the first testing time stab t1, and the second speed of download b1 reported by the second terminal and the second testing time stab t2, Third speed of download a2 that first terminal reports and third testing time stab t3, the 4th speed of download b2 reported by the second terminal and 4th testing time stabbed t4.Wherein, the time difference of the first testing time stamp t1 and the second testing time stamp t2 are greater than time threshold Value, i.e. the first speed of download a1 and the second speed of download b1 are that different terminals are tested to obtain in different moments；The third testing time The time difference for stabbing t3 and the 4th testing time stamp t4 is less than time threshold, i.e. third speed of download a2 and the 4th speed of download b2 It is that different terminals are tested to obtain at the close moment, optionally, which is arranged to 5s.

Further, server determines whether the WiFi network enables speed limiting function according to target detection data.Due to opening After opening speed limiting function, the speed of download of different terminals upper limit value having the same, and the sum of different terminals speed of download upper limit value Less than network total bandwidth, therefore, server detect the first speed of download a1, the second speed of download b1, third speed of download a2 and Whether the 4th speed of download b2 meets preset relation, and determines that WiFi network opens speed limiting function when meeting preset relation.

Wherein, the preset relation are as follows: the speed difference of the first speed of download and the second speed of download is less than threshold speed, and The speed difference of third speed of download and the 4th speed of download is less than threshold speed, and third speed of download and the 4th speed of download The sum of be greater than threshold speed with the speed difference of the first speed of download.It can be indicated with mathematic(al) representation are as follows: | a1-b1 | < k&& | A2-b2 | < k&& (a2+b2)-a1 > k.I.e. two terminals are close in the speed of download of different moments, and two terminals are in same a period of time The speed of download at quarter is close, and two terminals are greater than the speed of download of single terminal end in the sum of speed of download of synchronization.It can Choosing, threshold speed k can be 10k/s.

Optionally, when detecting the above-mentioned preset relation of target detection data fit, server determines that WiFi network is opened Speed limiting function, to set 1 for the value that the WiFi network corresponds to speed limit marker；When detecting that target detection data are not inconsistent It closes when stating preset relation, server determines that WiFi network does not open speed limiting function, so that the WiFi network is corresponded to speed limit mark The value for knowing position is set as 0.

As shown in figure 5, the test data that server is reported according to great amount of terminals 54, constructs WiFi net in database 531 Network and speed limit be identified as between corresponding relationship.

Step 408, associated data is reported to server, associated data includes IP address, MAC Address, packet loss and application At least one of information, server are used to determine the speed limit side that WiFi network uses according to the associated data that each terminal reports Formula.

When terminal initiates network request, dns resolution can be done to the domain name in network request first, if in local cache not There are the corresponding IP address of domain name, terminal needs to initiate to request to distal end dns server, obtains the corresponding IP address of domain name.It obtains After getting IP address, terminal can locally do domain name-IP address association caching, have the analysis request of same domain name again next time When, terminal can directly return to IP address.

However, distal end dns server may be WiFi equipment default configuration, it is also possible to manual setting, but after being arranged It cannot dynamic mapping in the request；Also, there is delay in the request of terminal to dns server, and dns server carries out recurrence and looks into It askes there is also delay, these delays are time-consuming by the feedback for increasing network request；In addition, although being stored with portion in terminal local caching The corresponding relationship of point domain name and IP address, but cache-time and buffer memory be it is uncontrollable, after local cache understands, and need Distal end dns server is re-requested, it is time-consuming to increase request.

Therefore, other than optimizing the availability of WiFi network in terms of evading speed limit, terminal can also be in terms of DNS accelerates Optimize WiFi network.

Referring to FIG. 6, the flow chart of the WiFi network access method provided it illustrates another embodiment of the application.This Embodiment is applied to terminal 110 shown in FIG. 1 with the WiFi network access method and comes for example, this method may include following Several steps:

Step 601, DNS request, the application identities comprising target domain name and/or owning application in DNS request are obtained.

When application program or browse request obtain Internet resources, terminal obtains DNS request, wraps in the DNS request Containing target domain name to be resolved.

Optionally, it in order to which determination is that application requests obtains Internet resources, is also wrapped in the DNS request that terminal is got Program identification containing the application program for initiating DNS request.

For example, including target domain name www.xxx.com and application identities App1 in the DNS request that terminal is got.

Step 602, the corresponding target ip address of target domain name is searched from local mapping table.

In the present embodiment, terminal solidifies local cache, generates local mapping table, the local mapping table is in terminal Whole life cycle all exists, and not will receive terminal and restarts or the influence of the factors such as application crashes.

In a kind of possible embodiment, which includes that the mapping between high frequency domain name and IP address is closed System, and/or, the mapping relations between frequency applications and IP address, wherein the access frequency of high frequency domain name is greater than first frequency threshold Value, the frequency that frequency applications send DNS request are greater than second frequency threshold value.For example, the first frequency threshold value can be 10000 Times/day, second frequency threshold value is 20 times/day.

Optionally, server collects the mapping relations between the domain name and IP address that each terminal reports, and to domain name into The domain name that access frequency is greater than first frequency threshold value is determined as high frequency domain name, thus by high frequency domain name and IP address by row statistics Mapping relations be issued to each terminal, so as to terminal generate local mapping table.

Schematically, in local mapping table, the mapping relations between frequency applications and IP address are as shown in Table 4.

Table four

High frequency domain name	IP address
		www.xxx.com	119.75.217.109
www.yyy.com	119.75.217.110
		www.zzz.com	119.55.217.109

Optionally, since difference is liked in the access of different user, in order to make local mapping table be more in line with the access of user Hobby, terminal count the frequency that different application initiates DNS request, and the frequency for initiating DNS request is greater than second frequency threshold value Using being determined as frequency applications, and establish mapping relations of the frequency applications between IP address.

Optionally, when terminal searches target domain name corresponding target ip address, application belonging to detection DNS request is first No is frequency applications, if the application is frequency applications, terminal is searched in the mapping relations between frequency applications and IP address Target ip address；If the application is not frequency applications, or is found in the mapping relations not between frequency applications and IP address Target ip address, terminal then search target ip address from the mapping relations between high frequency domain name and IP address.

If thening follow the steps 603 there are target ip address (finding target ip address) in local mapping table；If local Target ip address (not finding target ip address) is not present in mapping table, thens follow the steps 604.

As shown in fig. 7, when existing in local mapping table 711, when arriving target ip address, terminal 71 directly acquires the Target IP Address；When in local mapping table 711 there is no target ip address is arrived, terminal 71 is further according to target domain name in local cache It is searched in 712.

Step 603, it if there are the corresponding target ip address of target domain name in local mapping table, is sent to target ip address Network request.

After finding the corresponding target ip address of target domain name, terminal directly sends network request to the target ip address, To obtain corresponding Internet resources.

Step 604, it if the corresponding target ip address of target domain name is not present in local mapping table, is looked into from local cache Look for the corresponding target ip address of target domain name.

Due to the data in local mapping table and non real-time write-in, the corresponding target ip address of target domain name may be simultaneously Local mapping table is not written, and is stored in local cache.

If thening follow the steps 605 there are target ip address (finding target ip address) in local cache；If local slow Target ip address (not finding target ip address) is not present in depositing, thens follow the steps 606.

Step 605, if there are the corresponding target ip address of target domain name in local cache, net is sent to target ip address Network request.

The embodiment of this step is similar to above-mentioned steps 603, and details are not described herein for the present embodiment.

Through the above steps 601 to 605, terminal can be in local mapping table or local cache with finding Target IP Location reduces domain name mapping time-consuming to avoid interacting with dns server.

Step 606, if the corresponding target ip address of target domain name is not present in local cache, DNS is sent to server Server inquiry request.

Under the same WiFi network, the network environment as locating for terminal is similar, and optimal dns server is relatively solid It is fixed, the corresponding relationship between WiFi network and dns server is stored in advance in the present embodiment, in server, wherein the correspondence is closed System reports (terminal reports WiFi network and the process of dns server corresponding relationship to be described in detail in following step) by each terminal.

Schematically, the corresponding relationship between WiFi network and dns server is as shown in Table 5.

Table five

The mark of WiFi network	Dns server
		WiFi001	DNS001
WiFi002	DNS002
		WiFi003	DNS001

As shown in fig. 7, including the mark of target WiFi network in dns server inquiry request, server 72 is i.e. according to mesh The mark of WiFi network is marked, the address of target dns server is searched in the corresponding relationship shown in table five, and look into terminal feedback Ask result.

If in the query result of server feedback include target dns server address, execute following step 607 to 608；If not including the address of target dns server in the query result of server feedback, following step 609 is executed.

Step 607, it if including the address of target dns server in the query result of server feedback, is taken to target DNS Business device sends DNS request.

Target dns server is under current network environment, delay and the minimum dns server of packet loss.Terminal is to target Dns server sends the DNS request comprising target domain name, by the corresponding target ip address of target dns server recursive query.

Step 608, the target ip address that target dns server is sent is received.

After receiving target ip address, terminal sends network request to target ip address, to obtain corresponding network money Source.

Through the above steps 606 to 608, terminal obtains optimal DNS under current WiFi network environment directly from server The address of server, to improve the success rate and efficiency of subsequent domain name mapping.

Step 609, if not including the address of target dns server in the query result of server feedback, parallel to extremely Few two candidate dns servers carry out delayed test.

In order to avoid reducing the probability of DNS pollution, it is stored in terminal and contains at least two candidate dns server address Configuration file, when the corresponding target dns server of target WiFi network not stored in server, terminal is i.e. parallel at least two A candidate's dns server carries out delayed test, and filters out target dns server based on delayed test result.

Optionally, terminal sends inquiry request to each candidate dns server parallel, and obtains each dns server Feedback time.

As shown in fig. 7, terminal 71 carries out ping test to each candidate dns server 73.

Step 610, minimum candidate dns server will be postponed and is determined as target dns server.

Further, the candidate dns server for postponing minimum (i.e. feedback is time-consuming most short) is determined as target DNS clothes by terminal Business device.

Step 611, the address of the mark of target WiFi network and target dns server is reported to server.

In order to improve other access target WiFi networks terminal domain name mapping rate, terminal is by target WiFi network The address of mark and target dns server reports to server, so that server stores the corresponding relationship.It is subsequent other The terminal of access target WiFi network can obtain the address of target dns server directly from server, avoid to candidate DNS Server carries out delayed test.

In other possible embodiments, terminal can be with the time-out time of customized DNS request and retransmission interval, and root Retransmission time is adjusted according to network condition, alternatively, terminal can send inquiry request using TCP connection, to guarantee stable connection And query safe, reduce the generation of DNS pollution.

In the present embodiment, terminal carries out domain name mapping by local mapping table and local cache, avoids terminal and DNS service Device interacts, to improve the rate of domain name mapping.

Further, when not stored target ip address in local mapping table and local cache, terminal is directly from service At device obtain target WiFi network environment under optimal dns server address, thus improve subsequent domain name mapping success rate and Efficiency.

Further, when optimal dns server under the not stored target WiFi network environment of server, from several candidates Dns server in filter out and postpone minimum target dns server and improve subsequent domain name mapping so that DNS be avoided to pollute Success rate.

Terminal carries out in network access procedure, when server is to terminal transmission data, in order to avoid there is network congestion, needs Data are sent by the way of slow turn-on.However, server is only receiving last consignment of data really during slow turn-on When recognizing packet, next batch data could be sent, and expands transmission window, slow turn-on needs is caused to take considerable time；Also, when clothes When business device and terminal room are connected using secure transport layer protocol (Transport Layer Security, TLS), since TLS is held Hand message consumes initial connection byte, and too long handshaking information needs piecemeal to send, and causes slow turn-on is time-consuming further to increase It is long.

Therefore, in addition to other than evading speed limit and/or DNS and accelerating the availability of aspect optimization WiFi network, terminal can be with Optimize WiFi network in terms of TCP accelerates.

In a kind of possible embodiment, as shown in Fig. 2, passing through between terminal 110 and network resource server 160 TCP accelerates server 150 to be connected.Include the following steps: when terminal carries out data transmission with network resource server

One, terminal accelerates server to send data acquisition request to TCP, and TCP accelerates server for asking data acquisition It asks and is forwarded to network resource server.

When obtaining Internet resources (i.e. data) from terminal needs from network resource server, first by data acquisition request It is sent to pre-set TCP and accelerates server, accelerate server that data acquisition request is forwarded to net source service by TCP Device.

Correspondingly, network resource server obtains corresponding Internet resources according to the Internet resources acquisition request, and will Internet resources are sent to TCP and accelerate server.

Two, terminal receives the data that TCP accelerates server to send, which is sent to TCP by network resource server and adds Fast server.

After the Internet resources that TCP accelerates server to receive network resource server feedback, i.e., Internet resources are forwarded to Terminal.

As shown in the left figure in Fig. 8, in the related technology, after establishing connection between terminal and network resource server, network Resource Server can send data first with a lesser transmission window (for 2 in figure), when the ACK for receiving terminal transmission is anti- When feedback, network resource server can just expand transmission window, and further send data, it is clear that due to initially send window compared with It is small, cause slow turn-on process slow.

In the present embodiment, TCP accelerates server to be not only used as the transmission medium between terminal and network resource server, can Choosing, in slow start stage, after the data for receiving network resource server feedback, in the ACK for receiving terminal feedback Before, TCP accelerates server to send pre- confirmation (ACK) packet to network resource server, and it is pre- that network resource server receives this After confirmation packet, know that current network does not occur congestion, to increase transmission window, continues to send data.

As shown in the right figure in Fig. 8, TCP accelerates server to receive the data that network resource server is fed back, thus will Data forwarding is to terminal, and at the same time, TCP accelerates server to send pre- ACK, instruction Internet resources clothes to network resource server Business device increase sends window, and continues to send next batch data.

Optionally, when the ACK for not receiving terminal feedback in scheduled duration, TCP accelerate server determining with terminal it Between network there is congestion, to stop sending pre- ACK packet.When receiving the ACK of terminal feedback in scheduled duration, TCP Server is accelerated then not say that the ACK is sent to network resource server.

Obviously, as shown in figure 8, by TCP server pre-determining mechanism, slow turn-on process is reduced, i.e., identical In time, network resource server sends the speed of data faster, has achieved the effect that optimize WiFi network.

It is intermediate transparent service since TCP accelerates service, is connected to terminal and network resource server, therefore TCP adds Fast server can perceive the variation of network rate.Optionally, TCP accelerates service to follow following several points: 1) when detecting end When locating network environment speed being held to be deteriorated, transmission rate is reduced；2) it when detecting that network environment speed locating for terminal improves, mentions High transmission rate；3) when slow turn-on has reached maximum bandwidth, current transmission rate is safeguarded.

Optionally, in order to realize that the dynamic of transmission rate adjusts, terminal also accelerates server to send current network speed to TCP Rate, so that TCP accelerates server to confirm according to current network speed adjust the transmission rate of packet in advance, wherein current network rate With the transmission rate correlation, i.e., when current network rate is lower than rate-valve value, it is pre- true that TCP accelerates server to reduce Recognize the transmission rate of packet, when current network rate is higher than rate-valve value, TCP accelerates server to improve (or holding) pre- confirmation packet Transmission rate.

In the present embodiment, accelerate the pre- affirmation mechanism of server by TCP, improves slow turn-on between server and terminal Process, so that the rate of speeding up data transmission, has achieved the effect that optimize network；Meanwhile TCP accelerates server according to terminal institute Locate the network state of WiFi environment, dynamic adjusts transmission rate, so that network be avoided congestion occur.
