METHOD AND SYSTEM FOR SENDING REQUEST FOR ACQUIRING DATA RESOURCE

The present disclosure describes a method and system for transmitting a data resource acquisition request, and relates to the field of data transmission technology. The method includes: when transmitting an acquisition request for a first data resource, obtaining, by a first node, locally-stored traffic scheduling policies of a plurality of secondary nodes associated with a resource server to which the first data resource belongs, wherein the traffic scheduling policies are generated by each of the plurality of secondary nodes based on a local traffic load status; selecting, by the first node, a target node among the plurality of secondary nodes based on the traffic scheduling policies of the plurality of secondary nodes; and transmitting, by the first node, the acquisition request for the first data resource to the target node. The present disclosure may mitigate the reduced back-to-source efficiency of a dynamic parent node caused by the continuous traffic overload, thereby improving the quality of the back-to-source acceleration service in the CDN service cluster.
