METHOD AND APPARATUS FOR MANAGING CONTROLLER IN SOFTWARE DEFINED NETWORKING ENVIRONMENT

摘要

A method and apparatus for managing a controller through status checking of a controller are disclosed. A controller management method performed by a controller state management apparatus in a Software Defined Networking (SDN) environment includes: setting a state report request to a controller to report state management information of the controller to the controller state management apparatus; And managing the controller based on the status management information of the controller included in the status report response, whether the status report response is received, which is a response of the controller for the set status report request. Therefore, in the multi-controller environment, it is possible to avoid the risk of failing to detect the failure state of the specific controller by performing the procedure of checking the status information of the entire controller from the center.
