Research on distributed mobile management of satellite network based on software define network

Abstract

Distributed mobility management (DMM) was an effective method to solve the mobile address handover.Therefore,it was considered to be a technology that can be applied to satellite network mobility management.A distributed mobile management scheme which based on software definition network (SDN) was proposed to solve the traffic redirection problem in satellite network.Different from the traditional DMM application scenario which was network-based or terminal-based,the SDN-DMM scheme implements location management and address handover in SDN controllers.Therefore,SDN-based satellite network distributed mobile management scheme can realize packet forwarding path optimization compared with traditional scheme,and it shows significant advantages in managementcost and traffic management.
