|1. (WO2013123846) DISTRIBUTED NETWORK CONTROL METHOD AND DEVICE|
|Title:||DISTRIBUTED NETWORK CONTROL METHOD AND DEVICE|
Disclosed is a distributed network control method. A plurality of controller nodes form a distributed controller network, and each controller node manages one or more exchanger devices. The method comprises: controller nodes receiving information reported by an exchanger, synchronizing network topology change information in the information among all the controller nodes, and storing host position information in the information into a distributed controller network; and when receiving a data stream processing request, the controller nodes querying destination address information about a data stream in the distributed controller network, and establishing a data exchange path for the data stream according to locally stored global network topology information. Also provided is a distributed network control device. According to the technical solution of the present invention, the performance bottleneck problem of a network controller can be solved.
