Abstract:
Full deployment of IPv6 addressing fails because nowadays Network Address Translation (NAT) devices are commonly used to extend internal private addressing from the global public IP addressing. The existing phone system uses the vertical model to solve issues relating to the NAT and mobility management. Also, the horizontal model has been studied, where a centralized Software-Defined network (SDN) controller is in charge of handling network functions such as NAT and mobility management. The goal of this paper is to propose a blockchain-based NAT management (BNATM) scheme to overcome the limitation that both the horizontal model as well as the vertical model face in relation with NAT and mobility management. Our proposal focuses on the idea that, if we use the blockchain technologies, each peer can easily obtain the necessary parameters required to handle the complicated NAT and mobility management procedures. Finally, this paper analyzes the latency comparisons among the proposed BNATM scheme, existing vertical model and centralized controller-based horizontal model.
