Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a diagram of an application environment of a wireless network connection method according to an embodiment. Referring to fig. 1, the wireless network connection method is applied to a wireless network connection system. The wireless network connection system includes a terminal 110, an access device 120, a target domain name server 130, and a target server 140. The terminal 110 is in network connection with the target domain name server 130 and the target server 140 through the access device 120. Where access device 120 may specifically be a wireless network device. After the terminal 110 accesses the internet through the access device 120, selecting a target domain name server 130 with the highest response speed from the domain name servers; querying the target server for a first network address based on the target domain name server 130; sending a request packet to the destination server 140 according to the first network address; collecting feedback data of the target server and each gateway passing through the target server 140 when receiving the request packet; extracting the packet loss rate of the local gateway from the feedback data; and when the packet loss rate is greater than the packet loss rate threshold value, performing public network connection in a special network networking mode.
The terminal 110 may specifically be a desktop terminal or a mobile terminal, and the mobile terminal may specifically be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The target server 140 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.
As shown in fig. 2, in one embodiment, a wireless network connection method is provided. The embodiment is mainly illustrated by applying the method to the terminal 110 in fig. 1. Referring to fig. 2, the wireless network connection method specifically includes the following steps:
s202, selecting a target domain name server with the highest response speed from the domain name servers.
The domain name server (DNS server) stores a table of domain names and IP addresses (IP addresses) corresponding thereto to resolve the domain names of messages. Typically, to ensure high availability of services, DNS requires the redundant support of each zone using multiple domain name servers.
In one embodiment, the terminal acquires the network address of each domain name server, then acquires the response speed of each domain name server through a ping command according to the network address of each domain name server, and selects a target domain name server with the highest response speed from the domain name servers as a target domain name server for a curve (Command line Uniform Resource locator) request. The Ping command constructs an ICMP request packet with a fixed format during operation, and then the ICMP protocol delivers the packet to the IP layer protocol together with the destination address. The IP layer protocol constructs an IP data packet by adding a Destination Address (Destination Address) and a local Source Address (Source Address) and other control information, and then transmits the IP data packet to the next protocol layer, namely a data link layer. The data link layer obtains the MAC address of the destination host (i.e. the physical address of the network card, which is the necessary address for the data link layer protocol to construct the data frame) by querying the ARP cache table or broadcasting the ARP request, and then constructs and sends the MAC frame. And then, corresponding response information is returned according to actual network conditions such as whether the network is connected, whether the host is reachable, whether the route is available and the like.
The following table shows network addresses of the domain name servers currently and mainstream used by the terminal, where the network addresses may specifically be IP addresses. After acquiring the network address of the domain name server currently used in mainstream, the terminal acquires the response speed of each domain name server through the linux ping command line according to the network address of each domain name server, and selects the target domain name server with the fastest response speed from the domain name servers, as shown in fig. 3, the target domain name server is the response speed information of the DNS 114 acquired through the linux ping command.
