Abstract
A method for virtual local area network fail-over management, a system therefor and an apparatus therewith are introduced herein. In the method for virtual local area network fail-over management in a hybrid software-defined network (SDN), a controller with a centralized management authority may manage some fail-over events that occur in each link or switch in a centralized manner. The controller may pre-calculate backup paths for each link or switch in case that fail-over events occur therefrom. Whenever the fail-over event occurs in some specific link or switch, the controller may deploy the pre-calculated backup path in response to the link down or switch down event, which may reduce the convergence recovery time for the VLAN path in case of fail-over events and improve the reliability of data transmission.
