Strategy adjustment method, data transmission method and system, server and storage medium

The embodiment of the invention relates to the technical field of communication, and discloses a strategy adjustment method, which comprises the following steps of: acquiring a network state of a working node; if the change of the network state meets a preset condition, adjusting a topology strategy of the working node; the adjusted topology strategy is sent to each working node, and the working nodes comprise a global node, a plurality of local nodes and a plurality of common working nodes. The embodiment of the invention further discloses a data transmission method and system, a server and a storage medium. According to the strategy adjustment method, the data transmission method and system, the server and the storage medium provided by the embodiment of the invention, the data transmission scheme can be matched with the dynamically changed wide area network bandwidth, and the data transmission performance is improved. 本发明实施例涉及通信技术领域，公开了一种策略调整方法，包括：获取工作节点的网络状态；若网络状态的变化满足预设条件，则调整工作节点的拓扑策略；将调整后的拓扑策略发送至每一工作节点，
