OpenFlow-Based Mobility Management Scheme and Data Structure for the Mobility Service at Software Defined Networking

Abstract

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.

A novel optimized resource management model for software defined future mobile networks

“…Park et al 20 proposed OMMs and a data structure for mobility services. MMEs were incorporated into one scheme to manage mobility functions and to organize new data structures based on LMAs (local mobility anchors) and MAGs (mobile access gateways).…”

Survey on PMIPv6-based Mobility Management Architectures for Software-Defined Networking

“…Data is tunneled back to the home network, but SDN controllers can negotiate route optimization to avoid the home network when reaching a CN from the visited network. Pill-Won Park et al [55] proposed an OpenFlow-Based Mobility Management (OMM) implementation using the PMI-Pv6 manner to locate mobility management requirements. Their architecture proposal consists of Mobility Management Entity (MME), which existed in the SDN controller and handles all mobility management functions (Figure 29).…”

Future Trends in Mobile-Fixed Integration for Next Generation Networks

“…Moreover, these approaches are a suitable tool for mobility support by using OpenFlow protocol. OpenFlow-Based Mobility Management (OMM) (Park, Kim & Min, 2016) and OpenFlow-Based PMIPv6 with a centralized mobility management controller (OPMIPv6-C) (Kim, Choi, Park et al, 2014) are centralized approaches referred to PMIPv6. However, the mobility functions are developed through OpenFlow functionalities.…”
