CDN bandwidth resource planning method and device, electronic equipment and storage medium

The embodiment of the invention relates to the technical field of communication, and discloses a CDN bandwidth resource planning method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a target bandwidth waveform of a target customer in a target domain name region within a preset period; selecting i nodes as a target, traversing plannable nodes of a target client in the target domain name region to obtain (2N-1) node combinations, i = 1, 2,..., N, N being the total number of the plannable nodes, and the node combinations being different from each other; respectively determining the bandwidth cost generated by the node combination when the bandwidth represented by the target bandwidth waveform is averagely planned to i plannable nodes in the node combination; planning the plannable node in the node combination with the minimum bandwidth cost to a target client as a target planning node; and averagely planning the bandwidth represented by the target band
