METHOD AND DEVICE FOR MOBILITY MANAGEMENT BY SERVICEUSING MULTIPROTOCOL LABEL SWITCHING IN SDN ENVIRONMENT

摘要

A method for mobility management by a service using multiprotocol label switching (MPLS) in a software defined network (SDN) environment according one embodiment of the present invention may comprise: (a) a step of receiving, from an access point (AP), a Packet_IN message transmitted by a user terminal to the access point; (b) a step of determining whether there is a mobile node (MN) identifier matching the Packet_IN message by using data pre-stored in a server; and (c) a step of selecting one of a plurality of switches as an anchor to which the user terminal is connected, on the basis of whether there is a matching mobile node identifier.
