Abstract: The present invention relates to a software defined optical network controller deployment method based on multi-path survivability protection, and belongs to the technical field of networks, which is applied to the deployment of layer 2 SDN controllers.

The scheme contains redundant controllers, and the number of controllers needs to be further reduced. The present invention verifies whether the fault probability of each switch is lower than that required by the user by adopting the posteriori thought, that is, according to the deployment result.
