A conflict detection and solving method and device, which relate to the technical field of communications, are suitable for the scenario where a data stream is transmitted in a network, and are used for blocking the data stream from an overall perspective of a path of the data stream in the entire network. The conflict detection method comprises: acquiring, by a controller, a stream path of a data stream in a network, wherein the stream path is used for representing a path in which the data stream passes at least two intermediate nodes in the network and then reaches a destination address range from a source address range, a first stream table rule is added into or deleted from a stream table of each of the at least two intermediate nodes, and the first stream table rule is any stream table rule; and determining, by the controller, whether a conflict exists or not according to the address range of the stream path and the address range of a security policy. |
