Conflict detection and resolution methods and apparatuses relate to the field of communications technologies, and are applicable to a scenario in which a data flow is transmitted on a network, and are used to block a data flow from an overall perspective of a path of a data flow on an entire network. The conflict detection method includes: acquiring, by a controller, a flow path of a data flow on a network, where the flow path is used to indicate a path along which the data flow reaches a destination address range from a source address range through at least two intermediate nodes on the network, a first flow table rule is added to or deleted from flow tables of the at least two intermediate nodes, and the first flow table rule is any flow table rule; and determining, by the controller, whether a conflict exists according to an address range of the flow path and an address range of a security policy. |
