Fig. 2 is a flow diagram of a method for network access in one embodiment. As shown in fig. 2, the network access method includes steps 202 to 205.
Specifically, the domain name server set may be a domain name server list or a domain name server array, and the domain name server set is generated by one or more domain name servers configured by the electronic device according to the Wi-Fi network after the electronic device connects to the Wi-Fi network. Different Wi-Fi networks are connected, and the number of domain name servers acquired by the electronic device may be different, for example, when the connected Wi-Fi network is a home network, the electronic device may acquire one domain name server, and when the connected Wi-Fi network is a network in a public place, the electronic device may acquire a plurality of domain name servers.
And step 204, adding an alternative domain name server in the domain name server set when the judgment result shows that the network access can not be carried out through the domain name server.
In this step, when the electronic device has a network access requirement, the electronic device traverses the domain name servers in the domain name server set until an available domain name server is found, and performs a website query according to the domain name server. When it is determined that the electronic device cannot perform network access through the domain name servers in the domain name server set, an alternative domain name server may be added to the domain name server set, and the electronic device may acquire the alternative domain name server in a process of traversing the domain name server set.
Step 205, network access is performed through the alternative domain name server.
For step 205, the alternate domain name server may select a public network domain name server. The public network domain name server is a domain name server system used by a network operator as a basis, and a professional third-party high-reliability domain name server service platform is built through expansion, and is generally placed according to administrative regions, such as provinces. The platform can be composed of a large number of high-end Central Processing Unit (CPU) cores, and a user can set the public network domain name server as an alternative domain name server within a range covered by a delivery area of the platform and perform network access through the public network domain name server.
Different alternative domain name servers can be selected for network access according to different geographic locations. For example, different alternative domain name servers may be selected in china and non-china, where the alternative domain name server may be set to "114.114.114.114" and the alternative domain name server may be set to "8.8.8.8". The alternative domain name server set as '114.114.114.114' has nodes in China provinces, can satisfy telecom, Unicom, mobile and other operators, and is a safe and reliable alternative domain name server in China. The alternative domain name server set to "8.8.8.8" is a public network domain name server issued by google, which has no node in china, and can be set as an alternative domain name server in a non-chinese area for network access through the alternative domain name server.
In the Chinese area, besides "114.114.114.114", other reliable public network domain name servers can be set as alternative domain name servers, and the reliable alternative domain name servers can be selected for network access according to the geographic position and the network evaluation result released by each public network domain name server. Similarly, in non-Chinese areas, other reliable alternative domain name servers can be selected for network access according to the geographic position and the network evaluation result released by each public network domain name server.
In the network access method in this embodiment, when it is determined that network access cannot be performed through the domain name servers in the domain name server set, the alternative domain name servers are added to the domain name server set, and network access is performed through the alternative domain name servers, so that when the domain name servers acquired by traversing the domain name server set are all unavailable, the electronic device can perform network access through the alternative domain name servers.
In one embodiment, step 202 may determine whether network access is possible through a domain name server in the set of domain name servers by: acquiring historical query success rates corresponding to all domain name servers in a domain name server set; the historical query success rate is obtained according to the number of times of successfully querying the website in the website query record of the domain name server and the total query number; and when the historical query success rates are all smaller than the query success rate threshold, judging that the network access cannot be carried out through the domain name servers in the domain name server set.
In the above embodiment, the domain name server website query record is a record of performing website query through each domain name server in the domain name server set, where the record includes a record of whether each domain name server succeeds in querying each time. The historical query success rate can be the ratio of the number of times of successfully querying the website in the website query record of the domain name server to the total number of times of querying, and can also be the percentage of the number of times of successfully querying the website to the total number of times of querying. Before the domain name server queries the website, the historical query success rate of the domain name server can be obtained, and if the historical query success rate of the domain name server is smaller than a success rate threshold value, the domain name server can be judged to be unavailable; if the historical query success rate of each domain name server in the domain name server set is smaller than the success rate threshold, it can be determined that network access cannot be performed through each domain name server in the domain name server set.
In the above embodiment, before the domain name server performs the website query, it is first determined whether the domain name server is available through the historical query success rate threshold of the domain name server, and when it is determined that the domain name server is not available, the website query is not performed through the domain name server. The method and the device can avoid the electronic equipment from carrying out website query work through the unavailable domain name server, and reduce unnecessary query work.
In one embodiment, step 202 may further determine whether network access is possible through a domain name server in the set of domain name servers by: when the historical query success rate is greater than or equal to the query success rate threshold, performing website query through the domain name server; and if the website query fails, judging that the network access cannot be carried out through the domain name server.
When the domain name server set is traversed to obtain the domain name server, if the historical query success rate corresponding to the obtained domain name server is larger than or equal to the query success rate threshold, the operation of performing website query through the obtained domain name server can be performed, and whether the website query is successful or not is judged.
The following describes how to determine whether the website query is successful in combination with an example. After the electronic device connects to the router, if two domain name servers are obtained, the addresses corresponding to the two domain name servers are "192.158.1.1" and "192.158.1.2", respectively, the electronic device may add the addresses of the two domain name servers to the domain name server set. In the domain name server set, the domain name server address represents the corresponding domain name server. When the electronic device needs to perform network access, for example, when the electronic device needs to access the domain name "www.baidu.com", the electronic device will sequentially send a website query request to each domain name server in the domain name server set. When the electronic device sends the website query request to the domain name server "192.158.1.1", if no reply is received or other wrong returns are received, it is considered that the website query by the domain name server "192.158.1.1" fails, and the electronic device will continue to send the website query request to the domain name server "192.158.1.2". If the domain name server "192.158.1.2" returns an Internet Protocol Address (IP Address) corresponding to "www.baidu.com", if "153.177.151.110", it is considered that the query of the website Address by the domain name server "192.158.1.2" is successful.
If the website query is successful, the electronic equipment can access the network through the domain name server; if the website query fails, the electronic device cannot perform network access through the domain name server, and the electronic device can continue to traverse the domain name server set to acquire other domain name servers. The success or failure of the query can also be added to the statistics of the historical query success rate.
In the above embodiment, before the domain name server performs the website query, it is first determined whether the domain name server is available through the historical query success rate threshold of the domain name server, and when it is determined that the domain name server is not available, the website query is not performed through the domain name server. The method and the device can avoid the electronic equipment from carrying out website query work through the unavailable domain name server, and reduce unnecessary query work.
In one embodiment, when the historical query success rate is greater than or equal to the query success rate threshold, after the domain name server queries the website, the duration of the domain name server querying the website may also be obtained, and if the duration exceeds a specified duration, it is determined that the network access cannot be performed through the domain name server.
In the above embodiment, the timeout interruption is added in the process of performing the website query by the electronic device through the domain name server, that is, if the electronic device does not receive the IP address returned by the domain name server within the specified time, the website query is considered to be failed, and the electronic device cannot perform the network access through the domain name server. The electronic device may add an alternative domain name server in the domain name server set, and perform network access through the alternative domain name server.
The embodiment can avoid the electronic equipment from performing website query work through the unavailable domain name server, and reduce unnecessary query work. And the failure of query or the overlong query time caused by the failure of response of the domain name server can be avoided.
In one embodiment, for step 204, an alternative domain name server may be added by: and when judging that the network access can not be carried out through each domain name server, forbidding each domain name server, and adding an alternative domain name server in the domain name server set.
After each domain name server in the original domain name server set is disabled, the electronic device skips the disabled domain name server sets during traversal of the domain name server set, and directly performs network access through the alternative domain name server. When the electronic equipment has network access requirements, the step of searching for the available domain name server can be skipped, and the alternative domain name server is directly adopted for network access, so that the network access speed is improved.
In one embodiment, for step 204, an alternative domain name server may also be added by: and when the domain name server is judged to be incapable of performing network access, deleting the domain name servers with the historical query success rate smaller than the query success rate threshold in the domain name server set, and adding the alternative domain name servers in the domain name server set.
In the above embodiment, all domain name servers with a historical query success rate smaller than the query success rate threshold are unavailable, and deleting the domain name servers can avoid time waste when the electronic device traverses the domain name server set to acquire the unavailable domain name servers. The number of the alternative domain name servers added in the domain name server can be one or more. The Global Positioning System (GPS) location of the electronic device may also be obtained before adding the domain name server. An appropriate alternative domain name server is selected based on the GPS location of the electronic device.
In one embodiment, step 205 may comprise: and inquiring the website through the alternative domain name server, and accessing the network according to the inquired website.
When receiving a query request of the electronic device, the alternative domain name server may obtain a domain name to be queried carried in the query request, and analyze the domain name to be queried to obtain an IP address corresponding to the domain name. When the alternative domain name server is in website query operation, a domain name resolution database can be established on the electronic equipment or the alternative domain name server. The domain name and its corresponding IP address in the network access request may be stored in a domain name resolution database.
According to the embodiment, when the network access request is received, the IP address corresponding to the domain name to be inquired can be determined through the domain name resolution database, the frequency of sending the domain name resolution request to the alternative domain name server can be greatly reduced, the resource consumption and the network flow of the alternative domain name server can be saved, and the speed of obtaining the network access information can be improved.
In one embodiment, when the number of the alternative domain name servers in the domain name server set is multiple, the first location information of the electronic device and the second location information of each alternative domain name server may be obtained, and the first location information and each second location information may be matched. The location information may be GPS location information or network location information. And determining the successfully matched alternative domain name server as the optimal alternative domain name server, and performing network access through the optimal alternative domain name server.
The first location information may be matched with the respective second location information by: and comparing the first position information with each piece of second position information, and if the first position information is consistent with the second position information or the distance between the first position information and the second position information is within a specified range, determining that the first position information is matched with the second position information.
According to the embodiment, the speed of the alternative domain name server for responding to the network access request is increased by determining the optimal alternative domain name server, the network access speed is further increased on the premise of ensuring the successful network access, and the user experience is improved.
An embodiment of network access by an electronic device is described below in conjunction with fig. 3. When the electronic device is to perform a network access, a website query may be performed through a domain name server in the set of domain name servers, as shown in step 302 of fig. 3. When the website address is queried, step 304 may be executed, step 306 is executed by traversing the domain name server set, and step 308 is executed if the next domain name server exists in the domain name server set. If the next domain name server exists, the next domain name server in the domain name server set is obtained, step 310 is executed to obtain the historical query success rate of the domain name server, step 312 is executed, and whether the domain name server is available is judged according to the historical query success rate corresponding to the domain name server. If the domain name server is not available, returning to step 304, if the domain name server is available, executing step 314, performing website query through the domain name server, and updating the historical query success rate of the domain name server according to the success or failure of the query record. After the historical query success rate of the domain name server is updated, step 316 is executed to determine whether there is no available domain name server in the domain name server set and no alternative domain name server is included, if yes, step 318 is executed to add an alternative domain name server in the domain name server set, and network access is performed through the alternative domain name server.
According to the network access method, when no available domain name server exists in the domain name server set and the alternative domain name server is not included, the alternative domain name server is added in the domain name server set, and network access is performed through the alternative domain name server. The method and the device can avoid the electronic equipment from carrying out website query work through the unavailable domain name server, and reduce unnecessary query work.
As shown in fig. 4, in one embodiment, there is provided a network access method comprising the steps of:
In step 404, when the historical query success rates are all smaller than the query success rate threshold, it is determined that network access cannot be performed through the domain name servers in the domain name server set.
And 406, when the historical query success rate is greater than or equal to the query success rate threshold, performing website query through the domain name server. Step 308 and step 310 may be performed separately after step 305.
And step 408, if the website query fails, determining that the network access cannot be performed through the domain name server.
In step 412, if the duration exceeds the specified duration, it is determined that network access cannot be performed through the domain name server.
After determining that network access is not possible through a domain name server in the set of domain name servers, steps 414 and 416 may be performed.
And 414, when judging that the network access can not be carried out through each domain name server, forbidding each domain name server and/or deleting the domain name servers with the historical query success rate smaller than the query success rate threshold in the domain name server set, and adding the alternative domain name servers in the domain name server set.
And step 416, performing website query through the alternative domain name server, and performing network access according to the queried website.
Before the domain name server queries the website, the network access method judges whether the domain name server is available or not through the historical query success rate threshold of the domain name server, and judges whether the corresponding domain name server is available or not according to the website query duration when the website is queried. The method and the device can avoid the electronic equipment from carrying out website query work through the unavailable domain name server, and reduce unnecessary query work. When judging that the network access can not be carried out through the domain name servers in the domain name server set, forbidding each domain name server and/or deleting the domain name servers with the historical query success rate smaller than the query success rate threshold value in the domain name server set, adding the alternative domain name servers in the domain name server set, and carrying out the network access through the alternative domain name servers, so that the electronic equipment can carry out the network access through the alternative domain name servers when the domain name servers acquired by traversing the domain name server set are unavailable.
