Server node selection method and terminal device

A terminal device, comprising at least one processor and a memory, wherein the memory is configured to store one or more computer programs that, when executed by the at least one processor, enable the terminal device to perform operations comprising:

• sending a domain name resolution request to a DNS server, wherein the domain name resolution request carries a domain name, and the domain name resolution request requests an IP address corresponding to the domain name;
• receiving a plurality of IP addresses fed back by the DNS server in response to the domain name resolution request, wherein each of the plurality of IP addresses corresponds to a server node in a plurality of server nodes;
• sending a connection request to one server node in the plurality of server nodes at a first moment;
• determining whether the terminal device receives, before a second moment, response information fed back by the one server node in response to the connection request;
• upon determination that the terminal device receives, before the second moment, the response information fed back by the one server node, establishing a connection to the one server node;
• upon determination that the terminal device does not receive, before the second moment, the response information fed back by the one server node, sending another connection request to another server node in the plurality of server nodes at the second moment;
• receiving first response information at a fourth moment, the fourth moment being between the second moment and a third moment;
• establishing a connection to a server node that sends the first response information, wherein the server node that sends the first response information is the one server node or the another server node;
• sending, by the terminal device, a network resource request to the server node that sends the first response information, wherein the network resource request requests a network resource;
• determining whether the terminal device does not receive, within a second preset duration, the network resource fed back by the server node that sends the first response information in response to the network resource request;
• and
• upon determination that the terminal device does not receive, within the second preset duration, the network resource fed back by the server node that sends the first response information, sending, by the terminal device, a network resource request to the server node that sends second response information.

A non-transitory computer-readable storage medium, comprising one or more computer programs that, when run on a terminal device, enable the terminal device perform operations comprising:

• sending a domain name resolution request to a DNS server, wherein the domain name resolution request carries a domain name, and the domain name resolution request requests an IP address corresponding to the domain name;
• receiving a plurality of IP addresses fed back by the DNS server in response to the domain name resolution request, wherein each of the plurality of IP addresses corresponds to a server node in a plurality of server nodes;
• sending a connection request to one server node in the plurality of server nodes at a first moment;
• determining whether the terminal device receives, before a second moment, response information fed back by the one server node in response to the connection request;
• upon determination that the terminal device receives, before the second moment, the response information fed back by the one server node, establishing a connection to the one server node;
• upon determination that the terminal device does not receive, before the second moment, the response information fed back by the one server node, sending another connection request to another server node in the plurality of server nodes at the second moment;
• receiving first response information at a fourth moment, the fourth moment being between the second moment and a third moment;
• establishing a connection to a server node that sends the first response information, wherein the server node that sends the first response information is the one server node or the another server node;
• sending, by the terminal device, a network resource request to the server node that sends the first response information, wherein the network resource request requests a network resource;
• determining whether the terminal device does not receive, within a second preset duration, the network resource fed back by the server node that sends the first response information in response to the network resource request;
• and
• upon determination that the terminal device does not receive, within the second preset duration, the network resource fed back by the server node that sends the first response information, sending, by the terminal device, a network resource request to the server node that sends second response information.
