Method and apparatus for buffering and obtaining resources, resource buffering system

A resource buffering apparatus, comprising:

• a processor;
• and
• a memory, wherein the processor is configured to execute computer-executable instructions stored in the memory to perform operations of:
• obtaining an access popularity value of a resource, and obtaining first load values of cache servers where determining that the access popularity value reaches a preset first threshold;
• and
• determining one or more duplication cache servers from the cache servers for duplicating the resource according to the access popularity value and the first load values, and notifying the one or more duplication cache servers to duplicate the resource from a first cache server that stores the resource;
• when the access popularity value of the resource is lower than the first threshold, determining a second cache server among the cache servers that already buffers the resource according to second load values of all cache servers that buffer the resource and a required quantity of duplicates of the resource, and notifying the determined second cache server to delete the resource;
• wherein the determined second cache server has a load higher than other cache servers that already buffer the resource.

A non-transitory computer readable storage medium, storing computer instructions for buffering a resource, wherein the computer instructions when executed by a hardware processor instructs the hardware processor to implement following operations:

• obtaining an access popularity value of a resource, and obtaining first load values of cache servers when determining that the access popularity value reaches a preset first threshold;
• and
• determining one or more duplication cache servers from the cache servers for duplicating the resource according to the access popularity value and the first load values, and notifying the one or more duplication cache servers to duplicate the resource from a first cache server that stores the resource;
• when the access popularity value of the resource is lower than the first threshold, determining a second cache server among the cache servers that already buffers the resource according to second load values of all cache servers that buffer the resource and a required quantity of duplicates of the resource, and notifying the determined second cache server to delete the resource;
• wherein the determined second cache server has a load higher than other cache servers that already buffer the resource.
