Method, system and device for adjusting load of resource server

A device for adjusting loads of a plurality of resource servers under a target domain name, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the computer program is executed by the processor to implement a method for adjusting loads of a plurality of resource servers;

• wherein the method comprises:
• for each respective resource server of the plurality of resource servers:
• recording operation data of the respective resource server through an access interface provided by the respective resource server located at a respective IP address of the respective resource server;
• determining a quality fluctuating value of the respective resource server in a current detection period in accordance with a historical feature value of the respective resource server and operation data of the respective resource server recorded in the current detection period, wherein the historical feature value is calculated based on operation data of the respective resource server, and the historical feature value indicates an average quality parameter of the respective resource server over the current detection period and one or more previous detection periods;
• and
• reading a load weight value currently used by the respective resource server, adjusting the load weight value based on the quality fluctuating value, and determining a new load weight value of the respective resource server after the current detection period according to the adjusted load weight value;
• and
• sending a scheduling policy characterizing the new load weight values of the plurality of resource servers to a DNS authoritative server which assigns access requests directed to the target domain name to the plurality of resource servers according to the scheduling policy.

A non-transitory computer storage medium storing a computer program, wherein the computer program is executed by a processor to implement a method for adjusting loads of a plurality of resource servers under a target domain name;

• wherein the method comprises:
• for each respective resource server of the plurality of resource servers:
• recording operation data of the respective resource server through an access interface provided by the respective resource server located at a respective IP address of the respective resource server;
• determining a quality fluctuating value of the respective resource server in a current detection period in accordance with a historical feature value of the respective resource server and operation data of the respective resource server recorded in the current detection period, wherein the historical feature value is calculated based on operation data of the respective resource server, and the historical feature value indicates an average quality parameter of the respective resource server over the current detection period and one or more previous detection periods;
• and
• reading a load weight value currently used by the respective resource server, adjusting the load weight value based on the quality fluctuating value, and determining a new load weight value of the respective resource server after the current detection period according to the adjusted load weight value;
• and
• sending a scheduling policy characterizing the new load weight values of the plurality of resource servers to a DNS authoritative server which assigns access requests directed to the target domain name to the plurality of resource servers according to the scheduling policy.
