As described in the background art, the ADNS server resolves the domain name of the Internet Service accessed by the user to the IP entry address with the fastest theoretical speed according to different geographic locations and access ISPs (Internet Service providers), but the network entry IP returned according to the configuration mode may have poor access quality for some users, or even be unreachable, and the ADNS server may continuously return the same address to the user due to lack of effective feedback, so that the user with poor access quality or even unreachable may not use the Service all the time.
In order to solve the above problems, the present invention creatively provides a DNS scheduling method, device, and computer device, which process network access quality data of a client accessing a service according to a configured IP address, and update the configured IP address according to the network access quality data, so as to ensure that an IP address with good service quality is returned to a user, thereby improving the network connectivity rate of the client.
The DNS scheduling method, device and computer apparatus provided in the present invention will be further described with reference to specific embodiments.
The first embodiment is as follows: the present embodiment provides a DNS scheduling method, which is shown in fig. 1 and fig. 2, and includes:
s110, receiving an inquiry request sent by the mobile APP and a domain name input by a user, and reading an IP address of the user, wherein the inquiry request comprises an A result inquiry request or an AAAA result inquiry request.
Specifically, the mobile APP of the client attempts to query the a result or the AAAA result corresponding to the user input domain name using the http dns service of the IP-connected ADNS. And after receiving the query request of the mobile APP and the user input domain name carried by the query request, the ADNS reads the IP (Internet protocol) of the mobile APP, namely the user IP address, and records the IP as uIP.
The ADNS is an authoritative GSLB DNS server of an internet company, and the HttpDNS interacts with a DNS (Domain Name System) server by using an HTTP protocol, so that Domain Name resolution efficiency is improved. The DNS is a distributed database on the internet as a mapping between domain names and IP addresses, enabling users to access the internet more conveniently without remembering IP strings that can be read directly by machines. The process of finally obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution).
The result of (a), (address) is used to specify the IP address record corresponding to the domain name, and at the same time, the sub-domain name of the domain name can also be set, and the target address of the result of a can only use the IP address.
The AAAA result is a DNS record used to resolve a domain name to an IPv6 address, otherwise the same as the a result.
And S120, acquiring an IP address list corresponding to the domain name input by the user based on the query request, the domain name input by the user and the IP address of the user.

s121, inquiring and acquiring user geographical position information and user ISP information based on the user IP address, wherein the user geographical position information comprises user country/province/city geographical position information.
And the ADNS maps the user IP address to the user geographical position information according to a preset database.
Specifically, ADNS uses a GeoIP database to map the user IP address to national/provincial/municipal geolocation information (denoted GeoInfo) and ISP information. GeoIP, or geocation IP, means the geographic location based on an IP query. ISP full name (Internet Service Provider), i.e. "Internet Service Provider".
Illustratively, the geographic location information and the ISP information of the corresponding user are "china/guangdong/guangzhou. china mobile" according to the user IP address and the user IP database.
And S122, mapping an A result or an AAAA result according to the query request, the user input domain name, the user geographic position information, the user ISP information and the current scheduling strategy to obtain an IP address list corresponding to the user input domain name.
Preferably, S122 includes:
preferably, the present step comprises:
s1221, mapping an A record list or an AAAA record list corresponding to the user input domain name according to the query request, the user input domain name, the user country/province/city geographical location information, the user ISP information and the current scheduling strategy.
S1222, according to the A record list corresponding to the domain name input by the user, obtaining the IPv4 address list corresponding to the domain name input by the user, or according to the AAAA record list corresponding to the domain name input by the user, obtaining the IPv6 address list corresponding to the domain name input by the user.
Since the a (address) record is used to specify an IP address record corresponding to a domain name, and a sub-domain name of the domain name may also be set, and the AAAA record is a DNS record used to resolve the domain name to an IPv6 address, it is necessary to process the a or AAAA record to obtain a corresponding IP address list.
Specifically, a domain name input by a user, GeoInfo and ISP information are input into an ADNS scheduling module, when an inquiry request comprises an A result inquiry request, the ADNS scheduling module reads an A record list corresponding to the domain name input by the user from a configuration database according to a current scheduling strategy, and then obtains a corresponding IPv4 address list according to the A record list; when the query request comprises an AAAA result query request, the ADNS scheduling module reads an AAAA record list corresponding to the domain name input by the user from the configuration database according to the current scheduling strategy, and then acquires a corresponding IPv6 address list according to the AAAA record list.
S130, reading the performance parameters of each IP address in the IP address list corresponding to the domain name input by the user from the database, and processing the IP address list corresponding to the domain name input by the user based on the performance parameters to obtain a configured IP address list.
Specifically, the performance parameter includes an available state and a connection establishment duration, specifically, an available state and a connection establishment duration from (user geographical location information, ISP information) to the server IP address, where the available state is available or unavailable.
Preferably, the processing the IP address list corresponding to the domain name input by the user based on the performance parameter to obtain the configured IP address list includes:
and sorting and filtering the IPv4 address list or the IPv6 address list based on the performance parameters to obtain a configuration IP address list.
More preferably, the method specifically comprises the following steps:
s131, reading the user geographical location information and the user ISP information from the database to the available state and the connection establishing duration of each IP address in the IPv4 address list or the IPv6 address list, wherein the available state is available or unavailable.
Specifically, the available state and the connection establishment time of the server IP address in the IP address list corresponding to the user input domain name are read (user geographical location information and user ISP information) from a database (a network quality database for storing network access quality data).
S132, filtering the IP addresses with unavailable states in the IPv4 address list or the IPv6 address list according to the available states to obtain an available IP address list.
And filtering unavailable IP addresses in an IP address list corresponding to the domain name input by the user, ensuring that all the IP addresses in the configuration IP address list fed back to the mobile APP are available, and preventing the unavailable IP addresses fed back to the mobile APP from being unavailable so as to cause the condition that the mobile APP cannot normally access services by using the unavailable IP addresses.
S133, sequencing the IP addresses in the available IP address list according to the connection establishing duration to obtain a configured IP address list.
Specifically, the connection duration refers to the connection duration from (user geographical location information, ISP information) to the IP address of the server.
And sequencing the IP addresses in the available IP address list according to the connection duration, sequencing from short to long according to the connection duration to obtain a configuration IP list, and selecting the IP address with the shortest connection duration by the mobile APP in front of the short connection duration.
And if the unavailable IP address is filtered out and then the unavailable IP address does not exist, feeding back the IP address list of the default configuration to the mobile APP.
S140, feeding back the configured IP address list to the mobile APP and receiving the network access quality information sent by the mobile APP when the mobile APP accesses the Internet service based on the configured IP address list.
Specifically, after obtaining the configuration IP list, the mobile APP selects an IP access service according to a preset rule, and illustratively, selects an IP address access service closest to the mobile APP in the configuration IP list, that is, an IP address with the shortest connection duration for access. And the mobile APP accesses the Internet service by using the IP address, and if the permission of the user agreement is obtained, the network access quality information is recorded and asynchronously uploaded to the data reporting service module. And the data reporting service module receives the network access quality information recorded by the mobile APP when the IP address is used for accessing the service.
Preferably, the network access quality information includes a client IP address and a server IP address during access, DNS resolution time, whether a connection is successful, TCP connection establishment time, and TLS negotiation time. The network access quality information is obtained by recording after the mobile APP obtains the client user agreement permission.
And the mobile APP asynchronously reports error information in a full quantity mode, and the successfully accessed network quality information is reported to the data reporting service module in a sampling mode, and the data reporting service module transmits the network access quality information to a real-time/offline data warehouse for storage. If the immediate reporting is unsuccessful, the uploading can be delayed. The time interval for delaying the uploading is preset.
S150, processing the network access quality information to obtain the real-time performance parameters of the IP address currently used by the mobile APP, and updating the performance parameters of the IP address currently used by the mobile APP stored in the database according to the real-time performance parameters.
Specifically, the data processing module reads and processes network access quality information from the real-time/offline data warehouse, and generates actual connection duration from (user geographical location information, ISP information) to the server IP address according to the client IP address.
Preferably, the present step comprises:
s151, triggering off-line task processing network access quality information in real time or at regular time to obtain performance parameters, wherein the performance parameters comprise the geographic position of a user and the connection duration from an ISP (internet service provider) to a server IP (Internet protocol) address;
s152, judging whether the current performance parameters are the same as the performance parameters read from the database at the previous time, and if not, entering S153.
Specifically, it is determined whether the performance parameter of the server IP address currently used by the mobile APP is the same as the available state and connection setup time from the server IP address (user geographical location information, user ISP information) read from the network quality database for storing the network access quality data in S131.
S153, updating the corresponding performance parameters in the database for dynamically updating and feeding back the configuration IP address list of the mobile APP.
Specifically, the performance parameters stored in the database are updated with the current performance parameters.
For example, in S133, a list of configured IP addresses with connection duration from short to long is obtained: IP1, IP2, IP3, IP 4. The performance parameters corresponding to the IPs 1, IP2, IP3, and IP4 stored in the database are the quality information from (GeoInfo [ guan zhou city, guangdong province ], ISP [ china mobile ]) to the 4 IPs in the past 1 hour (available, average connection duration is 0.01s), (available, 0.02s), (available, 0.04s), (available, 0.05s), and these data are aggregated from the number of accesses per minute and average connection duration of each IP in the 1 hour. The mobile APP selects the first IP address IP1 to access the service after receiving the configured IP address list, and records and asynchronously reports the network access quality information of its access to the real-time/offline data warehouse after obtaining the user agreement permission.
The data processing module acquires a large number of access times and connection establishment duration data of IP1, IP2, IP3 and IP4 corresponding to 1 minute of past (GeoInfo, Guangzhou, Guangdong province, ISP, China Mobile) from a real-time/offline data warehouse. And then obsolete access data, and the average connection time of the past 1 hour is recalculated according to the data. After updating, the IP address performance parameters of the domain name corresponding to the user location (GeoInfo [ guangzhou, guangdong province ], ISP [ china mobile ]) stored in the database may become: IP1 (available, 0.05s), IP2 (available, 0.03s), IP3 (available, 0.02s), IP4 (available, 0.04 s). The ADNS scheduling module sorts and filters the configuration IP addresses which are obtained in the list according to the performance parameters, wherein the configuration IP addresses are IP3, IP2, IP4 and IP 5. The server IP address used by the mobile APP will be changed from IP1 to IP 3.
In the DNS scheduling method provided in this embodiment, after the filtered and sorted configuration IP address list is configured for the mobile APP, the network access quality data of the mobile APP according to the configured IP address access service is stored and processed, and the performance parameter corresponding to the configuration IP address list is continuously updated, so that the ADNS returns to the network entry IP address with the best service for the mobile APP, the network connectivity rate of the mobile internet application is effectively improved, and the user experience of the application is improved.
