OPENFLOW CONTROLLER FOR SUPPORTING HANDOVER IN PROXY MOBILE IPV6 BASED ON SOFTWARE DEFINITION NETWORK AND CONTROL METHOD THEREOF

摘要

According to an embodiment of the present invention, an openFlow controller for supporting a handover of a mobile node in a proxy mobile IPv6 environment based on a software definition network comprises a storage unit in which a handover policy is stored; and a processor which performs the handover policy. At this time, the processor determines the handover of the mobile node which is connected to a first mobile connection gateway according to the handover policy, selects a second mobile connection gateway as the handover target, and respectively sends a message to the first mobile connection gateway, the second mobile connection gateway, and a local mobility anchor, according to the handover policy so that the data packet is delivered through the second mobile connection gateway, instead of the first mobile connection gateway when the local mobility anchor connected to the openFlow controller delivers a data packet to the mobile node.;COPYRIGHT KIPO 2015
