The invention provides a data transmission method and device based on an organizational structure, routing equipment, a server and a storage medium, and relates to the technical field of the Internet.The method is applied to a routing node in a data transmission system. The data transmission system further comprises at least one service cluster. Each service cluster comprises a plurality of service nodes; each service node included in the same service cluster corresponds to different service organization types, wherein the at least one service cluster is connected with the routing node through a service bus. The method comprises the steps of receiving a service request sent by a first service node, sending the service request to a second service node in at least one service cluster, receiving service data fed back by the second service node according to the service request, and sending the service data to the first service node, wherein the service request carries an identifier of thesecond service node. According to the invention, data intercommunication between each service cluster and each service node in the data transmission system can be realized, the utilization rate of resources is improved, and the cost is reduced.
