摘要：The network-based mobility management is adapted to the OpenFlow architecture for mobility service at Software Defined Networking (SDN), and data structure for mobility service is proposed. SDN is a newly proposed Internet architecture which decouples the data and control planes, and mobility management is one of the most important issues in SDN. In order to provide mobility management service by utilizing the mobility scheme proposed earlier in a new network environment, the existing mobility schemes need to be modified. Particularly, the characters of the network environment need to be considered when designing the function of the network entities and data structure. Our proposed mobility management scheme is focused on the centralized control mechanism of SDN. We referred to Proxy Mobile IPv6 (PMIPv6) and OpenFlow-based PMIPv6 with a centralized mobility management controller (OPMIPv6-C). It has a merged data structure for the mobility service on SDN controller and minimizes the number of switches which need flow table modification at handover. At the performance analysis chapter, we compare the signaling cost at the registration and handover phase, packet delivery cost, and handover latency between the proposed scheme and OPMIPv6-C.
