Publication number: 20160315871Abstract: Disclosed is a method for processing a failure occurring in a network device. The method for processing the failure, performed in a network device connected to at least one controller, comprises the steps of: predicting the failure of the network device; and when the failure of the network device is predicted, notifying at least one controller that the network device will be down. Accordingly, by defining a processing mechanism for each type of router failure, all controllers concerned can quickly grasp the failure information of the router.Type: ApplicationFiled: December 11, 2014Publication date: October 27, 2016Applicant: KT CORPORATIONInventors: Eun Joo KWAK, Kwang Koog LEE, Young Wuk LEE
