METHOD AND SYSTEM FOR SENDING REQUEST FOR ACQUIRING DATA RESOURCE

The present disclosure describes a method and a system for transmitting a data source acquisition request, which relate to the field of data transmission technology. The method includes: when there is a need to transmit an acquisition request for a first data source, acquiring, by a first node, traffic scheduling information of a plurality of secondary nodes stored locally corresponding to a source server to which the first data source belongs, wherein the traffic scheduling information includes traffic-to-be-split domain name level and traffic-to-be-split ratio; selecting, by the first node, a target node among the plurality of secondary nodes based on the traffic scheduling information of the plurality of secondary nodes; and transmitting, by the first node, the acquisition request for the first data source to the target node. By using the present disclosure, the occurrence of a reduced back-to-source efficiency of a dynamic parent node caused by the continuous overloading of the traffic may be avoid effectively, thereby improving the quality of the back-to-source acceleration service in the CDN service cluster.
