The embodiment of the invention discloses a service network node configuration method under a district end-based network. The method comprises the following steps: detecting the average demand of each street in a region in a time period, and judging whether the average demand of each street in the time period is larger than a preset threshold or not; when the average demand of a certain street in the region in the time period is larger than the preset threshold, setting a service network node server for the certain street; when the average demand of the certain street in the region in the time period is smaller than the preset threshold, calculating to determine which streets in the region need to be served by the service network node server according to the genetic algorithm; and after calculating a plurality of the streets and configuring the service network node server, calculating the position of the center point of the plurality of the streets according to the absolute center point algorithm in the graph theory, wherein the position of the center point is the position for configuring the service network node server. By adopting the algorithm of the embodiment, service network nodes can be rapidly calculated and configured.
