Patent attributes
A method, system, and computer program product for open flow connection between differing software-defined network controllers are provided. The method generates a networking interface between a first networking controller and a second networking controller. Networking information is exchanged between the first networking controller and the second networking controller using the networking interface. A logical switch is generated between the first networking controller and the second networking controller by matching at least a portion of the networking information of the second networking controller at the first networking controller. The method exchanges the matched portion of the networking information from the first networking controller with the second networking controller to create layer two open flow connection between the first networking controller and the second networking controller.
