CDN network quality detection method and system, server and storage medium

The embodiment of the invention relates to the technical field of Internet, and discloses a CDN network quality detection method and system, a server and a storage medium. The method comprises the following steps: constructing a plurality of detection data packets, wherein each detection data packet carries a line identifier of one of a plurality of BGP lines from a CDN node to a target autonomous system AS; according to a line identifier carried in the detection data packet, sending the detection data packet to the target autonomous system from the CDN node through a BGP line corresponding to the line identifier; and respectively testing the plurality of BGP lines on the basis of the sent detection data packet to obtain network quality parameters of each BGP line so as to evaluate the quality of each BGP line between the CDN node and the target autonomous system AS, thereby providing support for related operation based on the network quality of each BGP line. For example, the optimal BGP line serving each ar
