Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A controller and a switch for network failure relieving from a software-defined networking (SDN) is provided. A method for operating the controller includes: transmitting, to the switch, path information for at least one packet and a session establishment message to establish a session for detecting a link failure of the at least one packet based on information regarding a capability of detecting a link failure of the switch. The method also includes receiving, from the switch, a session status message regarding a status of the session. If the status of the session is identified as the link failure, updated path information for the at least one packet based on information of the session is transmitted to the switch.

Abstract: A method of estimating an optical flow includes processing, using an image processing pass, a first image and a second image separately, and estimating the optical flow based on a second image attention feature map of the first image and a second image attention feature map of the second image. The processing using the image processing pass includes extracting a feature map by encoding an image, outputting a first image fusion attention feature map by fusing row relationship information of the image with the image feature map, outputting a first image attention feature map of the image based on the first image fusion attention feature map and the image feature map, outputting a second image fusion attention feature map by fusing column relationship information of the image with the first image attention feature map, and generating a second image attention feature map of the image based on the second image fusion attention feature map and the first image attention feature map.
