Ethernet address resolution in the context of dynamic IP address changes

While developing dynamic IP address changing techniques under current TCP/IP protocol cluster, the ARP request and reply messages of dynamic IP addresses must be carefully and effectively handled. In this paper, we propose a novel algorithm based on current ARP protocol and switch's self-learning algorithm to address the Ethernet address resolution problem in the context of dynamic IP address changes, which is designed to be deployed in the SDN environment. To evaluate the effectiveness of proposed algorithm, an experimental network was constructed by mininet. The hosts' ARP tables and OpenFlow switches' corresponding mapping tables in the experiment demonstrate that the proposed algorithm could fully satisfy the need of Ethernet address resolution in the context of dynamic IP address changes.
