Evaluation of Flexible Name Autoconfiguration for IoT Devices in IPv6 Network

摘要

Internet of Things (IoT) devices that are directly connected to IP networks are becoming popular, and it is expected that the use of IPv6 will increase in the future. Therefore, in order to communicate with IoT devices of various communication standards from remote locations using IPv6, it is considered that the setting of Fully Qualified Domain Name (FQDN) is indispensable. However, generally, existing IoT devices do not have a function of set FQDN dynamically, and it is necessary for users to set the FQDN of IoT device by themselves. We have proposed Flexible Name Autoconfiguration (FNAC) that automatically generates FQDN based on information obtained from IoT devices by utilizing existing communication protocols. In this paper, we develop a prototype system of FNAC, and measure the processing time from IoT device discovery to FQDN registration in IPv6 network. As a result, it was confirmed that FNAC could complete the series of processing immediately.
