IP flow mobility enables selected traffic to offload among various access networks. However, until now, only flow mobility schemes in the centralized architecture were considered. In this paper, we propose a flow mobility-enabled scheme based on the distributed mobility management networks to address the scalability issue and single point failure problems(More)
In recent years, service function chaining (SFC) has been developed besides software-defined networking (SDN) and network function virtualization (NFV), which open new opportunities for flexible provisioning and composition of network services. However, the adoption of SFC requires various security considerations to protect sensitive information in context(More)
In this paper, we provide a gap analysis to apply an IP-based distributed mobility management architecture that is standard in IETF to a 3GPP mobile core network. The IP distributed mobility management deployment model is obtained from the five models defined by the IETF DMM WG, and the 3GPP mobile core network is a 4G-based extended architecture and 5G(More)
