The invention discloses a distributed network control method. A plurality of controller nodes form a distributed controller network, and each controller node manages one or more pieces of switch equipment. The method comprises the following steps that: the controller node receives information reported by a switch, synchronizes network topology change information in the information among all the controller nodes, and stores host position information in the information into a distributed control network; and when receiving a data stream processing request, the controller node queries the destination address information of a data stream from the distributed controller network, and establishes a data exchange path for the data stream according to locally stored global network topology information. The invention also provides a distributed network control device. According to the technical scheme, the problem of performance bottleneck of a network controller can be solved.
